A '''Tactical Doll''' (战术人形), also called ''T-Doll'', is an AI-piloted android originally designed to serve as an easily replaceable fire platform for military operations. Early generation Dolls were unmistakably robots, but the standard form of Tactical Dolls came to be that of humans as the need of easier human-machine interaction appeared. While [[Girls' Frontline]] only features female Dolls, male Dolls exist within the story and playable ones have been introduced by [[Project Neural Cloud]]. After seeing heavy use in [[World War Three]], Tactical Dolls were made available on the civilian market after the war and non-combatant dolls were made commercially available. As of 2062, most T-Dolls are manufactured by [[IOP]] and can be found in use by national armies, police forces, PMCs, security companies, civilian companies and private citizens. [[Griffin & Kryuger]] combat forces exclusively employs T-Dolls.

In modern times, the term “Doll” specifically designates robots who embark a [[Neural Cloud]],<ref name=G36C4>{{cite|gfl|{{doll name|G36C|SMG|6|costume=costume5}} Neural Upgrade story 4}}</ref> while androids with simpler programming like the [[Cyclops]] are called “[[Automaton|automatons]]”<ref>{{cite|gfl|iso|Beyond the Border II, also [[Polarized Light]] Reflector I and Polishing, {{doll name|SV-98|RF|4|costume=costume3}} Neural Upgrade story 3, {{doll name|M1897|SG|4|costume=costume3}} Neural Upgrade story and {{doll name|Makarov|HG|3|costume=costume2}}'s A Certain Unscientific Sunflower costume story.

Within the story of the game, most playable Dolls belong to the [[Griffin & Kryuger]] base directed by [[the Commander]]. They are either purchased from [[IOP]] (through [[T-Doll Production|Production]]), who refits civilian Dolls with a Fire Control Core, or recovered from the field after having been lost or abandoned by other commanders (through map drops). Starting with the events of [[Dual Randomness]], [[Sangvis Ferri]] Dolls, most notably Ringleaders, have been inducted into G&K through [[Protocol Assimilation]].

Dolls with key roles in the main story may not actually be under the Commander's orders, but only playable for gameplay reason. This is the case of [[Squad 404]], who only occasionally works for G&K, and [[Task Force DEFY]], who are not affiliated with G&K at all. Starting with [[Fixed Point]], Dolls that are not story-critical can be played while not being affiliated with G&K, such as {{doll name|SP9|SMG|5}} and {{doll name|Sterling|SMG|5}} who work for the [[Stasi]], or {{doll name|VP1915|SMG|5}} and {{doll name|Savage 99|SMG|5}} who work for [[Griffin Lyons]]. In [[Longitudinal Strain]], Dolls previously playable but never seen in the story have appeared for the first time under other factions. It is not explained if they are to be interpreted as merely the same model.

The game also doesn't restrict the use of Dolls who may not be canonically available at certain points in the story, such as members of [[AR Team]] or Task Force DEFY, or the majority of the Commander's Dolls after the [[Paldiski Incident]] of [[Polarized Light]].

Many Dolls in Girls' Frontline identify with the culture of origin of their assigned weapon. In the index, the background of Dolls who are not part of a story team depends on their weapon's country of origin:
*The background of American Dolls is an eagle with the motto from the Great Seal of the United States “E Pluribus Unum” (“One From Many”), and the United States Capitol with B-2 Spirit stealth bombers.
*The background of German Dolls is a cross with the West German motto “Einigkeit, Recht, Freiheit” (“Unity, Justice, Freedom”), and the Brandenburg Gate.
*The background of Russian Dolls is a raised fist in a five-pointed star (both Soviet symbols) and “УРА!!!” (“Ura”), the traditional battle cry of Russian militaries, and the Spasskaya Tower with a line of what could be T-90 tanks.
*The background of Chinese Dolls is an Asian dragon with the stylized character 武 (wǔ, “military”), and a part of the Great Wall of China.
*The background of Italian Dolls is a centurion helmet with GPNVG-18-like night vision goggles, the motto of the Italian military “Una Vis, Una Vox” (“One Strength, One Voice”) and the Coliseum.
*The background of Belgian Dolls is a roaring lion with the national motto “L'union fait la force” (“Unity Makes Strength”) and the Gravensteen Castle.
*Dolls of other nationalities display a [[Griffin & Kryuger]] background.

For a detailed list, see the [[PNC:Doll Index]]. There are 70 playable Dolls as of 29 July 2023.

There are five Dolls classes in this game: 
*Warriors, who usually fight in close combat.
*Guards, who focus enemy fire and protect their allies.
*Snipers, who fight with long-range attacks.
*Specialists, who provide buffs for their allies and debuffs for enemies.
*Medics, who heal and protect their allies.

Each Doll has an upgradeable rarity and 18 attributes: Max HP, ATK, Hashrate, Physical DEF, Operand DEF, Attack Speed, Crit Rate, Crit Damage, Physical Penetration, Operand Penetration, Dodge Rate, Post-Battle HP Regen, Skill Haste, Debuff Resistance, Backlash, Damage Boost, Injury Mitigation and Healing Effect.

For more gameplay information, see [[Doll Info Menu]].

Unlike Girls' Frontline, few Dolls in Project Neural Cloud are Tactical Dolls. Most are civilian Dolls without a Fire Control Core, who are given the ability to fight due to the game taking place in the virtual world of [[Magrasea]]. Some are confirmed or suspected to be the same Doll as Girls' Frontline before they joined [[Griffin & Kryuger]]. A few playable characters such as {{hero_name|Hannah|Specialist|3}}, {{hero_name|Turing|Specialist|3}} and {{hero_name|Eos|Sniper|3}} are not actually Dolls at all despite being generically designated so, but purely virtual Magrasea agents.

Playable Dolls are members of Oasis or allied factions, but deployable parties in gameplay rarely align with their availability in canon, and some missions actually restrict deployed units to match the story. Dolls released alongside a personal story event usually canonically join Oasis during the event's story, but some Dolls are canonically part of Oasis long before they become playable, such as {{hero_name|Horizon|Specialist|3}}.

== Development and history ==
===Skeletal-Frame Robots precursors===
In the early 21st century, the bursting of the Relic bubble led to a global financial crisis, forcing companies around the world to look for a way to lower production costs or make technological breakthroughs, opening the age of automation. The Russian Federation was the leader of this race during the first decade thanks to the engineering legacy of the [[Soviet Union]]: while American, European and East Asian industrial machines and robotic arms were more high-tech, Kiev's automated research center was very competitive with its focus on ease of maintenance and price point made them very competitive.

The 2020s saw great development in fixed or wheeled heavy-weight automated mechanical arms, CNC tools, automatic circuit boards etching tools and similar equipment. Meanwhile, legged robots remained at conceptual or model stage due to their cost. The top engineering campuses of various nations produced miniature androids and multi-legged designs, becoming the foundation for later moving joints and balance designs. Be the end of the 2020s, conceptual designs in science exhibitions presented androids the same size as humans and multi-legged robots reaching 2 meter-tall.<ref name=CF22>{{cite|cf2|part. 2}}</ref>

Interest in this new branch of robotics soared soon after the [[First Beilan Island Incident]] as a way to replace human laborers and soldiers in the increasingly dangerous environment of Earth.<ref name=Timeline>{{cite|ab1|Timeline}}</ref>

The precursors to modern dolls are more accurately described as robots rather than android since production constraints gave them appearances far removed from humans. The first Skeletal-Frame Robots adapted for assembly-line production were developed in 2033 by a team led by [[Havier Witkin]] from LBT General Manufacturing (雷柏特通用制造公司). They had an autonomy of 6 hours for 4 hours of recharge, were versatile and able to quickly swap their equipment to reduce maintenance time, and their AI program could be changed to adapt to a variety of jobs. This list of specification made them revolutionary at the time and required two years of tremendous work to produce the final prototype.

Experimental models were internally designated ALR-50(T) for “Auto Labor Robot (Testing)”. The first batch of production models ALR-50 took 130 man-hours to produce, which was more than the units would produce in their operational life. This hitch was quickly improved on. The ALR-50E2 could work 20-hours days, but its design was too simple to enable it to swiftly change its own equipment configuration and later evolved into the ALR-51C (T), a skeletal-frame industrial robot combining operational life and effective interchangeability,<ref name=Files0Gen /> able to swap parts and suitable software depending on the requirements of the job. Human-scaled (though frightening due to its exposed head sensors), it incorporated 4 major limbs and 12 large joints able to simulate 24 human-like movements. It could be fitted with 48 different tool arms and suites as required to carry out various tasks. It could support 300 kilograms of weight, and had an internal batteries lasting 6 hours when wired power supply was unavailable. In theory it would have a lifespan of 9800 hours, though in practice it was closer to 9600 hours.<ref name=CF22 />

In order to support the Siberian Lifeline Program, aiming to restore the Siberian railway and nearby industrial facilities in contaminated areas, the Neo-Soviet Union opened a bid for automated machines able to operate 24 hours a day in Yellow Zones, dubbed the Universal Labor Robot project. Witkin's ALR-51C (T) was submitted by the Production and Technology R&D Consortium 766th Production and Technical Equipment Administration Department (生产和技术研发联合体第766生产和技术设备曹理局), and won at the end of the 6 months bidding period. While clumsy, the ALR-51C (T) still met the most requirement out of all bidding projects, only lacking in initial deployment time. It was simple and crude but cheap and sufficient for the project. Because of this, Witkin's ambitions to work on enhanced ALR frames were not supported by further funding. Meanwhile, wheeled, tracked and air-cushion hover robots development flourished under the lead of [[Sangvis Ferri]] Manufacturing in Romania, General Dynamics in the United States, SIMATIC in Europe and other industrial groups. Dozens of automated machines ranging from 0.5 to more than 10 meters would become the base for future military robots.<ref name=CF22 />

Despite winning the bid, the ALR-51C's complex design made it fall far behind the ALR-50E2 in strength tests and its flexibility tests were disappointing because no suitable AI had been developed yet. Witkin knew the ALR-51C could be improved into a revolutionary model with a suitable AI and more involved design, but the world situation was tensing and the market was shrinking. When work began on the ALR-52P series, even Witkin went to work on improving this model and forgot the ALR-51C.<ref name=Files0Gen /> The ALR-51C was given new life 15 months later by Westchester United Electronics Manufacturing Company's (韦杰斯特联合电子制造公司) 6th development studio head, Mihacj (米哈奇). Westchester had accepted a contract from the [[Pan-European Alliance]] to develop an autonomous system capable of using the [[Assault Artillery]] combat platform. Mihacj's team wanted to build a test platform themselves to gather initial data, but this proved extremely costly and he instead turned to external sources to buy an already existing platform to test on. This proved difficult too as the specifications needed were high for the current market, and Mihacj would have abandoned the project if he hadn't met Witkin during a mixer. Now Chief Robotics Project Supervisor, Witkin took a liking to Mihacj and pulled the necessary strings to sell the ALR-51C's blueprints and most of its databases to Westchester at low price. Two months later, Mihacj's project had adapted the operating system of the platform and made a breakthrough.

This model was very responsive to commands and its body structure was revamped to improve its stability, making its shape closer to modern dolls. It was known as the TD-01, for “Testing Doll”, and known to its designers as "Baby".<ref group=note>The Timeline in [[The Art of Girls' Frontline Vol.1]] claims that Autonomous Doll technology had entered its testing phase by 2033. However, these dolls are described as having human appearances and extremely high AI complexities and operational capabilities, able to help both in everyday life and combat roles. This is not consistent with the lore expressed in the [[Confidential Files]].</ref> The TD-01 had unprecedented operational flexibility, enabling it to cover the functions of several different existing platforms and pleasing the Pan-European military, which could reduce the operational cost of its Assault Artillery vehicles and increase the command efficiency of their mechanized units. Westchester reaped the profits, and the reputation of Mihacj was boosted. Mihacj's next idea was to replace the operating system used by the TD-01 by a dedicated AI, and began a joint development with LBT and Witkin. The two friends and their teams enjoyed a considerable budget and a dedicated research building with its own machine shop and multi-terminal computing system. Six months later, the TD-01 had received a strengthened structure, a revamped software, and a small quantity of artificial muscle fibers to test their power output. This model was called the CSD-02, for “Common Strength Doll”, and went through a rapid testing-iteration process, Mihacj's AI developers using the constant influx of data to tweak its processes. The CSD-02 was becoming an effective AI-piloted platform, but the structural complexity was still a problem. Witkin unenthusiastically searched for inspiration in the ALR-52P's design to try and reduce part count.

In parallel to the internal development of the CSD-02, other companies like Scheppel Advanced Technology Co.(斯切贝尔先进科技工业公司) sought to purchase IP rights to the platform to adapt it to their own purposes. Scheppel had become interested in the CSD-02 from AI experimental reports in order to fulfill a military contract. The military had troubles getting test data from its Assault Artillery systems because of the high casualty rates from its manned operators, and their main partner Westchester had already shifted its attention to AI systems when the problem arose. Scheppel filled this void to provide the military a doll capable of using Assault Artillery systems, with increased load capacity and force sensors in critical joints for easy data collection, and delivered the platform in 2041. Dolls equipped with this sensor package were designated CSD-03H, and their sensors system was reused in later models to improve agility and movement precision.<ref name=Files0Gen>{{cite|cf1|The Era of Production-Model Skeletal-Frame Robots}}</ref>

After Northern and Central Europe were swept by contamination during the 2035 Northern Lights Incident, the Soviets and the Europeans negociated the deployment of the then-confidential ALR models to the new contamination zones. The International Service for Military-Technical Cooperation was set up and Witkin was sent to Ukraine to found Important Operations Prototype Manufacturing Company, or [[IOP]].<ref name=CF22 /><ref group=note>The first [[Confidential Files]] contains a different origin story for IOP that was retconed by the second Confidential Files. In the original story, IOP was officially founded in 2046 after three years of planning by the collaboration of Westchester and Scheppel, in order to answer the demand of the Pan-European military, especially Chief of Staff [[General Carter]], for military-grade combat dolls capable of replacing flesh-and-blood soldiers. The new version of the story provides IOP with a focus on the civilian market.</ref>

In November of 2036, IOP unveiled the ALR-52P, widely recognized as the first model of skeletal doll due to the secrecy in which the Soviet government held the 51C (T). The 52P shared the 51C (T) 12-joint for 4-limb structure, with the addition of 24 smaller joints to increase its range of motion. It could simulate 72 human-like motions and choose among 128 different tools. Its maximum load and battery operation time was increased by 42% and its head unit had been changed from using exposed sensors to a liquid crystal display to perform basic interactions with human beings. Countries from Central and Eastern Europe ordered large quantities of 52Ps and IOP also effected a wealth of technology transfers and shared copyrights with other companies that had not set foot into the doll robot industry.<ref name=CF22 /> Over the next few years, many countries scrambled to develop their own models of dolls with specifications following their particular strategic vision.<ref name=CF23>{{cite|cf2|part. 3}}</ref> While the doll robot industry had its first breakthrough, legged, wheeled and tracked robots also continued to evolve. In 2036, the Soviet Union abandoned screw-driven all-terrain vehicles in favor of a new generation of legged platforms. In 2037, Kirov Robotics’ two-legged 10-ton platform, Chelyabinsk Mechanics’ two-legged 15-ton platform, Lower Tajir Locomotive Works’ 4-legged 20-ton platform and Omsk Transport Machinery Plant’s six-legged 35-ton platform all passed muster and the same year, General Dynamics rolled out the first generation of 8-legged all-terrain platforms.<ref name=CF22 /> In the 2040s, Gaterbillar introduced legged robots dedicated to disaster relief.<ref>{{cite|pnc|{{hero name|Cascadia|warrior|3}} Profile 1}}</ref>

The development of dolls and Witkin's efforts were of particular interest to the newly established [[Rossartrism|Rossartrists]], who believed fully automated labor would be critical to the evolution of society.<ref name=CF22 />

===First Generation Tactical Dolls===
Witkin sensed the dolls market could go beyond military organizations and spent time finding partners to solve the incoming technical challenges of advanced doll systems and raise interest in the civilian and security markets. Witkin registered three wholly-owned subsidiaries of IOP in the US, Ukraine and China to find local partners. The Ukraine branch entered a partnership with the rapidly growing [[Sangvis Ferri]] Manufacturing, who were more interested in the toughness of the ALR-52P than the advanced technologies of the CSD-03H and invested large amounts of money in IOP while also offering to provide AI researchers.<ref name=Files1G />

In 2040, amidst the rising international tensions of the Second Algerian War, Sangvis Ferri unveiled its [[Ripper]] combat doll model, built on the ALR-52P frame. Designed with military specs, it boasted a bulletproof casing, multifunctional helmet and could accommodate one weapon. However, the Rippers were slow and clumsy, making a poor display during the 2042 Ukrainian Civil War when the 20 first-generation units were quickly reduced to scraps by the trained militias. A second, better armored generation was deployed, but they were still too slow and allowed human enemies to take aim at their weak points.

Meanwhile, IOP ignored the military doll market and focused on civilian service dolls. Anticipating the mass exodus of the young population of Europe after the Ukrainian Civil War, Witkin focused on making a doll closely resembling a human being to serve as caregiver and workforce in countries with a growing imbalance in age ratio. The first generation of service doll based on the CSD frame with the appearance of adult women, the “Nymphs”, rolled out in 2043. It could simulate 12 human expressions and 128 human movements, efficiently replaced the working population and responded to any command from their clients due to not having any programmed negative emotions. After polishing the Nymphs through the first batches, the model quickly became a must-have in the service industry. By 2044, almost 36% of retirees in Eastern Europe had purchased an IOP service doll to help in their daily lives, with positives feedbacks reaching 85%. While doll technology had its successful break into the civilian market, the international military market rejected dolls more than ever. Armies around the world scrambling to upgrade their arsenal preferred large-scale multi-legged, wheeled and tracked robots capable of swiftly traversing mountainous terrain.<ref name=CF22 />

At the start of [[World War Three]] in 2045, Sangvis Ferri and IOP fell under the control of the Neo-[[Soviet Union]]'s Ministry of Defense. The ministry didn't trust combat dolls technology and both companies were only ordered transport dolls to serve on supply lines for the first two years of the war, totaling over 10 000 units. By May 2047, manpower shortage on the frontlines and the [[United States]]' landing in Europe convinced the ministry to order combat dolls for field testing. Sangvis Ferri used the Ripper as the base for the specialized [[Jaeger]] and [[Vespid]] models. Because they had never worked on military models before, IOP chose to militarize the CSD frame, eschewing SF's specialization paradigm to keep an all-purpose platform. The CSD's ability to replicate a wide range of human movements made it proficient in the operation of different types of weapons. Designs were submitted by June 2047 and production began, with the ministry planning to test the dolls on various frontlines before deployment against the US military, but when the US launched an armored assault campaign in Germany in August 2047, the ministry had no choice but bolster their defense lines with barely tested combat dolls. Dolls AI at the time lacked the necessary adaptability to survive autonomously on a battlefield, had to be commanded at close range, the SF model lacked agility and the IOP suffered from constant malfunctions. Few of the 8000 units survived the campaign, but they nevertheless crushed the armored assault with startling efficiency, convincing the ministry to invest into combat dolls,<ref name=CF22 /> deploying them on the Lybian front as early as November 2047.<ref name=CF25>{{cite|cf2|part. 5}}</ref> IA controls quickly became semi-smart, with units devising battle plans automatically. Three years later in 2050, SF and IOP models displayed vastly improved performances during Operation Tradewind, fighting alongside multi-legged assault platforms and swiftly breaking mountain defenses in Southern Italy and pressuring Rome to surrender.<ref name=CF22 />

Sangvis Ferri became an important partner for IOP as production demand became higher and higher, and IOP subcontracted part of its production to SF and provided them technical documents to modify the Tactical Dolls. The Jaegers produced by SF became widely used on the frontlines while the CSD series was falling out of favor because its autonomy and frequent malfunctions due to its complexity made it unreliable on the battlefield, and they were relegated to gun platforms used by the military police and derided as target practice by frontline personnel. IOP lost contracts to SF, which enraged Witkin, and the relations between the two companies soured. Witkin nevertheless pushed for versatile Tactical Dolls and worked to improve the AI and reliability of the CSD series, but didn't get satisfying results, demoralizing IOP's teams.

In 2049, Mihacj discovered from one of his students articles about an underground research group called [[90wish]]. Witkin was impressed by the technological capacities and development drive of the group and tried to contact them, but the group seemed completely inaccessible. Witkin learned from the Russian Internal Internet Security Bureau that 90wish was in an internal debacle, as all its members had not approved going public. Through a contact in the Ministry of Internal Affairs, Witkin learned of two former 90wish members whose lives were threatened by their former comrades: [[Persica|Persicaria]] and [[Lycoris]]. Witkin hired a PMC to escort them to IOP's buildings, which succeeded though the PMC soldiers suffered casualties.<ref name=Files1G /> The Ministry of Internal Affairs was also involved in the mission to secure Persicaria.<ref name=Files2G /> Both scientists agreed to work for IOP under false identities as members of a company called Hermit, contracting with IOP.<ref name=Files1G /> At 90wish, Persica and Lycoris had created the Inverted Forest framework, a neural simulation framework which would eventually lead to the creation of the [[Neural Cloud]]s powering Second Generation T-Dolls.<ref>{{cite|gfl|sc|Fractured Cognition IV}}</ref> Hermit's work included Lycoris' tree-shaped command system based on his AI prototype {{enemy name|Elisa|boss}}, which enabled great direct command efficiency and was advantageous to implement a variety of algorithms and encryption modes.<ref name=Files2G /> Lycoris and Persicaria enabled several breakthrough in the CSD series' development, leading to the CSD-08A and CSD-08B models, the experimental IAD series and the production ACD series, regaining the favors of military clients for their reliability, resilience and capacity to be used both on frontlines and as manual laborers.

The ACD series were deployed in the Nordic campaigns and were used as sentinels instead of frontline fighters due to their lacking AI. IOP had sacrificed flexibility in favor of fewer part count and structural stability and added layers of armor, increased the density of the titanium alloy used in the framework to make Tactical Dolls more resilient. They made a smaller head unit to reduce their target surface and encased the camera unit in 10mm steel plates. Visual control and guidance modules were relocated in the armored thorax and relied on waveguides rather than physical cables. Interface ports in the neck and lower spine allowed an operator to take control if the AI system was lost. The ACD-50 had a scanning radius of 220m, could function in action for 28 hours on full charge or 55 hours on standby and was cheap to buy and maintain. The ACD-51 entered production during the last year of the war<ref group=note>The ACD-51 is numbered after 2051, the last year of World War Three according to the first [[Confidential Files]]. Other materials disagree with this date (see [[World War Three#Conclusion]]).</ref> and lowered the center of gravity to make using heavy weaponry more reliable, expanded internal storage and load capacities to solve ammo supplies problems, but reduced the scanning range to a radius of 200 meters and the autonomy to 21 hours in action or 48 hours on standby. These downgrades were of no consequence for the military clients compared to the improvements. The additional R and T series were reconnaissance and special operations models produced in small quantities.<ref name=Files1G />

A major incident occurred during Operation Black Forest in 2050, when an advanced CSD-119A Doll and her unit affiliated with the British Royal Dragoons were ordered to open fire on civilians, but refused to comply and deserted. This put the military in an awkward position, as it demonstrated that Dolls could in fact disobey orders, but they would have to admit that they had given illegal orders. The affair was covered up, the responsible Doll was trialed on 13 November 2050 but released without a sentence, and militaries limited the adoption of Dolls with advanced AI. The truth behind Operation Black Forest would only be revealed in 2064.<ref name=Lee>{{cite|gfl|{{doll name|Lee-Enfield|RF|6|costume=costume4}} Neural Upgrade story}}</ref>

The ACD-series Tactical Dolls were the most used during World War Three, with 11 730 units produced, including 2300 from Sangvis Ferri's factories.<ref name=Files1G>{{cite|cf1|The First Generation of Tactical Dolls}}</ref>

===Second Generation Tactical Dolls===
[[File:Dolls Artworks 2015.jpg|thumb|A-Dolls and rebellious Doll.]]
The civilian dolls market grew after the end of World War Three as the production, service and PMC sectors were short in manpower. IOP enjoyed a comfortable market share thanks to its relations with major PMCs and international industrial companies.<ref name=Files2G /> After the end of World War Three, Private Military Companies were hired by the weakened governments to control growing population unrest in Western Europe and the new colonies in Africa. Faced with dissident factions equipped with the abundant military gear abandoned at the frontlines, many PMCs quickly turned to Tactical Dolls.<ref name=CF22 /> An early adopter of Tactical Dolls and a major client of IOP was [[Griffin and Kryuger]] (G&K), who heavily relied on cheaper armed civilian Tactical Dolls. G&K was given a direct feedback channel to Hermit, enabling Persicaria to improve the CSD-06, CSD-07 and CSD-08 series, develop the SST-02A and SST-03 models and develop the Service Dolls series dedicated to civilian markets, with emotional simulation software and gendered appearances, and later improve man-machine interaction with attractive appearances and customization capabilities. Receiving contracts from governments, business companies, civilian services companies and private individuals, IOP's revenues boomed.<ref name=Files2G />

In 2052, the Soviet National Research Center announced their answer to the growing problem of short battery autonomy in all kinds of autonomous robots by designing a contained plasma, slow release and discharge power cell, enhancing the autonomy of dolls from 20 to 150 hours. This new kind of power cell was also safer due to its strong resilience to EM interference complemented by an automatic conversion of its power into a powerful electrical pulse when the magnetic field containing the plasma was broken, instead of an explosion.<ref name=CF22 /> By 2054, Persicaria had completed her [[Etching Theory]] and laid the groundwork for adapting 90wish's [[Zener Protocol]] to T-Dolls.<ref name=Timeline /> The result was the concept of Second Generation T-Doll,<ref name=Files2G>{{cite|cf1|The Second Generation of Tactical Dolls}}</ref> using a modular chassis based on the prototype from the earlier IAD series.<ref name=Files1G /> Witkin supported the continuous improvement of T-Dolls, but refused to add funds to Lycoris' autonomous AI research. This frustrated Lycoris, who decided to join Sangvis Ferri. SF hired G&K to escort Lycoris to their underground research labs, with his subsequent research results as payment. Lycoris' defection led to Witkin increasing even more Persicaria's funding, and in 2057 she founded [[16Lab]], a first-party manufacturer of IOP.<ref name=Files2G /> 

The same year,<ref name=Timeline /> 16Lab improved the Zener Protocol into the [[Dummy Network]] system, introducing a differentiation between mainframe dolls with complete software and hardware capabilities, and dummy dolls with reduced functions. While this increased the cost of mainframes, it lowered the cost of dummies and made the overall price of a dummied team lower. This created a serious price advantage for IOP.<ref name=Files2G /> A year later in 2058, Persicaria finalized her personal project:<ref name=Timeline /> [[Imprint Technology]], enabling T-Dolls to use already existing firearms. Imprint Technology was open-source, but 16Lab's proficiency over its inner workings resulted in IOP dolls still having the advantage in the market.<ref name=Files2G /> After [[World War Three]], high grade weaponry was supplied exclusively to military units and banned from civilian market. PMCs such as Griffin and Kryuger instead used outdated weapons ranging from the late 19th century to the 2010s.<ref>{{cite|gfl|ct|Chapter 1 Final Destination, {{doll name|RO635|SMG|5}} explains why G&K's [[Heavy Ordnance Corps]] are illegal.}}</ref>

All IOP dolls included Imprint softwares and Dummy Networking as a standard, and were sold in modular packages, finalizing the specifications for the Second Generation T-Dolls envisioned by Persicaria. She published the technical specifications, hoping other companies would follow them to unify all dolls control systems and production standards on the market.<ref name=Files2G /> In 2060, on G&K's request, IOP purchased the [[Neural Cloud]] recording system, reducing data losses during operations.<ref name=Timeline />

Over at Sangvis Ferri, in late 2054, Lycoris installed Elisa as the mainframe for computing human orders and relaying it to T-Dolls, making orders management extremely efficient though SF dolls were expensive to produce and Elisa suffered from lapses of consciousness Lycoris still needed to resolve. As SF established a new Dolls manufacturing plant in a dangerous but resources-rich area,<ref name=Timeline /> Lycoris exploited their robust manufacturing capabilities to eschew software compatibility with a wide range of firearms and develop miniaturized particle weapons and mount them on dolls, then testing the results and iterating. Individual SF dolls had better performance as a result and their capabilities was more unified.<ref name=Files2G /> On G&K's suggestion, the Dummy Network technology was presented to Lycoris but he showed no interest, too engrossed in his AI research.<ref name=Timeline /> When Sangvis Ferri disappeared as a manufacturer after the [[Butterfly Incident]] of 2061, all their work was lost in Area S09 and IOP basically controlled the Tactical Doll market, be it military dolls, armed civilian dolls or unarmed civilian dolls. Persicaria further developed the modularity and safety of T-Dolls by implementing the [[Fire Control Core]] concept.

The goal of IOP to standardize tactical and civilian dolls design was reached after 2062. IOP regrouped military dolls into the ACD series, while creating six civilian models grouped into the SST and SSD series.<ref name=Files2G />

The SST series (with the T standing for “Tactical”<ref name=Quench />) had good processor speed, high weapon compatibility and a lot of memory dedicated to human-machine interaction and emotions simulation. Their flagship product, the SST-05, was based on an early special warfare model and had lower specs than other models, but were widely available and had large Neural Cloud databases, meaning a lot of combat data was readily available to make dolls immediately efficient. The SST-05A, the most used model in G&K's frontline troops, was an upgrade compatible with the SST-05's combat data, with lesser software requirements and better hardware performance. The SST-05A2 was a custom-made special warfare model with performances close to military dolls and independently encrypted storage to make them safe to use on black operations, but costly and with limited storage dedicated to emotional simulation in favor of other specialized software.

The SSD series was intended to cover both the civilian and tactical market, with a large memory space dedicated to emotional simulation and third party interaction systems easily customizable by civilians and hundreds of appearance modules on the market, while still being compatible with Fire Control Cores for security and police applications. The SSD-62D was intended for the service industry and the SSD-62F for ceremonial purposes. The SSD-62G is intended for secret service duties as an intermediate level between police and military dolls, they are more expensive and less available, but very performant as they are customized for specific tasks.<ref name=Files2G />

Doll usage in high-skills occupations became so ubiquitous that models were created specifically to perform maintenance on other Dolls, such as [[Svarog Heavy Industries]]' [[Delacey|DMT-X]] series, and IOP created scientist Dolls to contribute to the advancement of Dolls design.<ref>{{cite|gfl|{{doll name|G36C|SMG|6|costume=costume5}} Neural Upgrade story}}</ref>

As an example of T-Doll market price, a [[Simo|Gaul-series]] second-generation Tactical Doll was worth 540,000 rubbles in the 2050s.<ref>{{cite|pnc|2-4}}</ref>

===Later improvements===
{{Spoiler}}
In 2061, Persica formed the [[AR Team]], an experimental T-Doll squad based on the brain scan of a human. One of the Dolls later integrated to the team was {{doll name|RO635|SMG|5}}, the first Third Generation T-Doll. Unlike previous Dolls who needed a base personality preset, RO635 was created with a blank core logic and exposed to various simulated, and later real situations in order to “enrich” her mind and personality in a non-deterministic fashion. Through self-determination, Persica believed third generation Dolls would be able to develop genuine love for themselves and the world around them, and bear powerful emotions that would lead to illogical actions, but also give them a new form of strength. Such capabilities were also part of Lyco's goal in AI development.<ref>{{cite|gfl|ct|Neural Fragment}}</ref><ref name=RO4>{{cite|gfl|{{doll name|RO635|SMG|6|costume=costume3}} Neural Upgrade Story 3 & 4}}</ref> The general public pushed back against the emergence of more independent Dolls, preferring second-generation Neural Clouds.<ref>{{cite|pnc|[[Project Neural Cloud#ARG|ARG]], screenshot_2797294210.jpg}}</ref>

At some point, [[Statesec]] contractor [[Minor Characters#Arthur Hume|Doctor Hume]] led private experiments aiming to reproduce the human memory system in Dolls, and especially the ability to recover lost memories through specific stimuli. His efforts led to the creation of [[Erma]] and the Summer Garden system.<ref>{{cite|gfl|ls|33}}</ref>

After the [[Butterfly Incident]], [[Griffin and Kryuger]] captured a [[Sangvis Ferri]] SPzH3000 Tactical Doll {{enemy name|Architect|boss}} after she surrendered. Her weaponry was studied by 16Lab and the ASST system was upgraded with Sangvis Ferri heavy weaponry operation technology, creating T-Dolls groups capable of operating weapons such as mortars and anti-tank shells launchers, dubbed [[Heavy Ordnance Corps]] (HOC).<ref name="CT_E3_Persica">{{cite|gfl|ct|E3-1, Witkin and Persica's dialogue regarding the studying of Architect and the research outcome}}</ref> HOCs teams integrate a spotter, a weapon operator, a weapon loader and sometimes a guard. The need for multiple T-Dolls acting as a unit may be because they are civilian T-Dolls of lower physical capabilities compared to Sangvis Ferri T-Dolls.

[[Svarog Heavy Industries]] partnered with Griffin & Kryuger and trademarked a High-Altitude Directed EMP Bombing Run service to enable the capture of Sangvis Ferri ringleaders.<ref>{{cite|gfl|Capture Operation bombing run screen}}</ref>

In 2094, during the [[First Antarctic War]], the [[Union of Rossartrism Nations Coalition]] used the Bear's Den secret site to mass-produce clones of [[Noylu]] and [[Jefuty]], subjects of the [[Three Goddesses project]], intending to include their DNA in next generations of Tactical Dolls. The clones were destroyed during [[operation Tinder]].<ref>{{cite|cf1|part 8}}</ref>

==Technical design==
===Orders management===
Most Dolls are capable of taking simple decisions for themselves, and when authorized can have hobbies and socialize by themselves when off-duty.<ref>{{cite|gfl|[[Butterfly in a Cocoon]]|Trackless Tears}}</ref> However, decisions relying on computationally complex factors are more difficult for Dolls, can cause dramatic misjudgements and can make Dolls adverse to taking their own decisions.<ref name=Sten1>{{cite|gfl|{{doll name|Sten MkII|SMG|4|costume=costume2}} Neural Upgrade Story 1}}</ref><ref>{{cite|gfl|7-4|{{doll name|Skorpion|SMG|3}} panics under fire because she can't act without orders.}}</ref> Commanders can give T-Dolls standing orders, or outfit them with preset stratagems so they can perform automated actions.<ref>{{cite|gfl|7-6|{{doll name|RO635|SMG|5}} uses a preset stratagem to conduct hostage rescue}}</ref>

====Command Protocol====
A command protocol is a time-limited authority a T-Doll can receive to lead a team. A command protocol has been used in cyberspace to create simulated echelons.<ref>{{cite|gfl|[[Glory Day]]|{{doll name|K2|AR|5}} demonstrates the capabilities and limitations of command protocol.}}</ref>

List of known dolls with/once had/speculated having command protocols:
*{{doll name|DSR-50|RF|5}} (Her unit's involvement during operation Deep Dive, also her being able to operate alone to fulfill her end of the deal struck with UMP45)
*{{doll name|K2|AR|5}} (K2 was given command protocol and a squadron to guard a city ruin)
*{{doll name|OTs-14|AR|5}} (OTs-14 Groza leads a squadron of T-Dolls of Russian origin, she is speculated as having command protocol)
*{{doll name|IWS 2000|RF|5}} (IWS leads a squadron of T-Dolls of Austrian origin, her squadron operated in cooperation with other T-doll echelons during chapter 8 night, she is speculated as having command protocol)
*{{doll name|Welrod MkII|HG|5}} (Welrod leads a squadron of T-Dolls of British origin, her squadron took part in the operations during chapter 8 night assisted IWS' squadron, she is speculated as having command protocol)

====Command Module====
Some T-Dolls are outfitted with a command module, which let them take decisions related to their main objectives and operate independently for short amounts of time.<ref name=Glossary /> The [[AR Team]] could operate as a task force with {{doll name|M4A1|AR|4}}'s highly-efficient command module,<ref>{{cite|gfl|7-4|{{doll name|M4A1|AR|4}} mentions her advanced command module}}</ref> and later with {{doll name|RO635|SMG|5}}'s basic command module.<ref>{{cite|gfl|7-6|{{doll name|RO635|SMG|5}} mentions her basic command module}}</ref> Command modules are resource-intensive and T-Dolls not designed primarily to use them will experience fatigue after using them for long periods of time.<ref name=RO94 /><ref name=DD34 />

List of known dolls with/once had command module installed:
*{{doll name|Five-seveN|HG|5}} (57 commented on her installed command module when she overtook the command of PP-90's garrison during event [[Hitoribocchi]])
*{{doll name|M4A1|AR|4}} (Leader of AR Team, M4A1 is the first T-Doll with the command module installed known to the newly arrived G&K Commander)
*{{doll name|RO635|SMG|5}} (RO635's command module was further developed based on combat data fed back from AR Team, later on fine-tuned by commanding Palette Squadron, RO's command module is speculated to be the most advanced version to date)
*{{doll name|AK-12|AR|5}} (As observed during [[Singularity]] and [[Continuum Turbulence]] campaign)

====AI delegation====
[[Sangvis Ferri]] Dolls take orders from the relay mainframe AI [[Elisa]], with orders trickling down the chain of command from {{enemy name|Elisa|boss}} to high-rank Ringleaders, then to lower-rank Ringleaders and finally to standard units.<ref name=Glossary />

====Exceptions====
{{doll name|UMP45|SMG|4}} was able to delegate her command authority to another T-Doll, {{doll name|UMP40|SMG|4}}, to receive commands from her instead of a human commander.<ref>{{cite|gfl|dd|2-3, Audio File 6}}</ref> When UMP40 died, UMP45 was free to take her own decisions instead of entering stand by mode. The origins of this unique amount of freedom has yet to be explained, it may be because UMP40's last wishes for her freedom were registered as valid orders, because of her origins as [[Sangvis Ferri]] T-Doll or because she was modified to cause the [[Butterfly Incident]].

[[Squad 404]] uses the equivalent of a command module containing the data of a commander to simulate human orders and act with total independence. This module is usually held by {{doll name|UMP45|SMG|4}} but has also been used by {{doll name|UMP9|SMG|4}},<ref>{{cite|gfl|dd|3-3}}</ref> though only UMP45 can use it for long periods of time.<ref name=DD34>{{cite|gfl|dd|3-4, {{doll name|UMP9|SMG|4}} reaches her limits of using 404's fake command module outside of consciousness Level II}}</ref> It has been suggested that {{doll name|HK416|AR|5}} could also use it.<ref name=45MOD2>{{cite|gfl|{{doll name|UMP45|SMG|4}} Neural Upgrade Story 2}}</ref>

===Imprint Technology (ASST)===
[[File:GFL Promo ASST.jpg|thumb]]
Imprint Technology (烙印技术, sometimes translated "Branding" by fans), officially called "ASST" for Advance Statistic Session Tool,<ref name=Handbook /> is a software relying on compiled code to improve the proficiency of a T-Doll with specific tools and weapons,<ref name=Files2G /> providing them an "instinctual" feel of how to best employ it<ref name=Glossary /> while also being able to track its real-time location.<ref name=Handbook /><ref name=M1919 /> It's an implementation of Etching Theory (蚀刻理论), a general concept to let two objects form a standalone connection<ref name=Glossary /> that [[Persica]] derived from Relic technology.<ref name=Handbook />

Imprinting does not prevent a T-Doll from using other weapons and many carry a sidearm and knife with them,<ref>{{cite|gfl|{{doll name|F2000|AR|2}} uses a sidearm in 6-1N, {{doll name|ST AR-15|AR|5|costume=costume2}} in 12-3 and [[Mirror Stage]] - Chaos’ Abyss III, and {{doll name|AK-15|AR|5}} in Mirror Stage - Pandora's Box III and Möbius Strip.}}</ref><ref>{{cite|gfl|{{doll name|M16A1|AR|4}} uses a knife in [[Polarized Light]] - Molding and [[Fixed Point]] E4-11, {{doll name|ST AR-15|AR|5|costume=costume2}} in [[Mirror Stage]] - Chaos’ Abyss III, {{doll name|AK-12|AR|5}} in Mirror Stage - The Prisoner’s Dilemma I and AK-15's Neural Upgrade story 3, and {{doll name|AK-15|AR|5}} in Fixed Point E4-11.}}</ref> but their proficiency with them is reduced compared to their imprinted weapon.<ref>{{cite|gfl|12-2E}}</ref><ref>{{cite|gfl|{{doll name|PPSh-41|SMG|4|costume=costume3}} Neural Upgrade story 2.}}</ref> An imprint can malfunction if the T-Doll is particularly adverse to the weapon she was assigned.<ref>{{cite|gfl|{{doll name|Mosin-Nagant|RF|4}} Neural Upgrade Story 1, Mosin hated her weapon at first and could only use her imprint properly after gaining pride from its history and legacy.}}</ref>

Though it is sometimes thought that training has no effect on Dolls,<ref>{{cite|gfl|dd|2-4}}</ref> it does lead to noticeable improvements<ref>{{cite|gfl|{{doll name|Bren|MG|4|costume=costume1}} Neural Upgrade Story 2}}</ref><ref>{{cite|gfl|{{doll name|UMP45|SMG|5|costume=costume3}} Neural Upgrade Story 1}}</ref><ref>{{cite|pnc|[[Sol]]'s quotes}}</ref> and can even enable a Doll to become proficient with a weapon without being Imprinted.<ref>{{cite|gfl|pr|E4-9, [[SP9|Mona]] is revealed to not have an Imprint.}}</ref> Dolls are provided with necessary fundamental skills in the form of data, but benefit from training their decision-making systems to better respond to complex situations.<ref name=Python22>{{cite|pnc|Quenching Operation, Stage 2-2}}</ref>

Imprint Technology was made public in 2057 by [[16Lab]], who maintained and updated ASST in the long-term. Since 16Lab is a first-party manufacturer for [[IOP]], IOP brand T-Dolls are the most effective when used with Imprint Technology. As an open-source technology, anybody can download the base ASST engine and customize their doll's operational program.<ref name=Files2G />

===Fire Control Core===
A later development by 16Lab, the Fire Control Core (FCC) contains all combat-related software in a physically removable module, making it easy to take away a T-Doll's combat capabilities. The FCC has a number of interface ports to make it fully compatible with any modification of Imprint software.<ref name=Files2G /> A Doll outfitted with an FCC can wield their weapon with more speed and precision than even highly-trained human soldiers.<ref>{{cite|gfl|[[Bounty Feast]], Chapter 0}}</ref><ref name=RPK />

Fire Control Cores take up set bandwidths within a T-Doll's operating system, operators can choose to fit lower grade Fire Control Cores to reserve space for other items such as E-War modules.<ref name="Deep_dive_E2_UMP40">{{cite|gfl|dd|E2-4, {{doll name|UMP40|SMG|4}} mentioned her low-grade Fire-Control Core to {{doll name|UMP45|SMG|4}}}}</ref> Shotgun imprints take a larger bandwidth compared to other types of weapons.<ref name=RMBCostume /> Like other parts of a T-Doll, the FCC can be hacked to hamper the Doll's ability to fight.<ref name=Molding>{{cite|gfl|pl|Molding}}</ref>

===Zener Protocol===
[[File:Zener Illustration.png|thumb|[https://en.wikipedia.org/wiki/Zener_cards Zener Cards].]]
The Zener Protocol (齐纳协议) is a wide area communication protocol built by [[90wish]]<ref name=Glossary /> and later modified by 16Lab in a doll operation network interface.<ref name=Files2G /> Similar to Peer-to-Peer technology, it enables a team of dolls to transmit messages to each others without relying on a mainframe or satellite uplink<ref name=Glossary /> so they can relay human orders and new tactical information. This enables a group of Dolls to function independently without a human command to an extent.<ref name=Files2G /> It is named after Karl Zener (卡尔·齐讷), who conceived a cards-based experiment for telepathy and extrasensory powers.

Error correction procedures can modify how an individual Doll perceives its environment in case of a mismatch between its sensor data and collated data from other Dolls in the network. This can work against the group in case of a mass hacking, as non-compromised Dolls will become affected as long as the majority is experiencing sensory alteration.<ref>{{cite|gfl|sc|E2-1}}</ref>

===OGAS Protocol===
Derived from the large-scale Soviet [[OGAS]] system, the OGAS command protocol is used by [[Sangvis Ferri]] T-Dolls instead of the Zener Protocol.<ref name=Singu1A1 /> Due to the fundamental differences between Zener and OGAS (one being mesh-based and the other tree-based), it is difficult for an IOP T-Doll to disguise herself as a Sangvis T-Doll,<ref>{{cite|gfl|sg|2-C Promotion I}}</ref> though not impossible.<ref>{{cite|gfl|9-1|{{doll name|RO635|SMG|5}} disguises herself and {{doll name|M4 SOPMOD II|AR|4}}'s signals to sneak past SF's foot troops, then trigger-happy SOP ruins everything}}</ref> Old DSI-8 models Sangvis T-Dolls like {{doll name|UMP40|SMG|4}} and {{doll name|UMP45|SMG|4}} can swap their operating system between Zener and OGAS.<ref>{{cite|gfl|dd|3-3, {{doll name|UMP40|SMG|4}} and {{doll name|UMP45|SMG|4}} swap to OGAS protocol to infiltrate Sangvis' main lab}}</ref><ref>{{cite|gfl|dd|2-4, {{doll name|UMP45|SMG|4}} swaps to OGAS protocol to counter [[Parapluie]]}}</ref>

===Dummy Network===
[[File:Dummy Network Illustration.png|thumb]]
A special application of the Zener Protocol, Dummy Networking (傀儡网络) is a command network protocol enabling a human command to be received by one doll, who would analyze and relay the command to the rest of its group. A team of dummied dolls functions about 37% more efficiently than a team relying only on Zener Protocol connection.

The protocol was optimized by separating dolls in "mainframes" and "dummies", with only the mainframes having the processor and synchronization software necessary to compute commands. Dummies are cheaper since they only carry imprint, scouting and combat software with minimal hardware functions. As a result, the total price of a dummied squad is lower than a squad of standard dolls.<ref name=Files2G /> Dummies are made in the semblance of the mainframe so they can be used as decoys.<ref name=Handbook /> In [[Girls' Frontline: Doll's Song|the manga]], which is not accepted as canon, dummies are differentiated visually from the mainframe by their cruder body details, making them look more robotic.<ref>''[[Girls' Frontline: Doll's Song]]'', ch. 4</ref>

Dummies can operate without a mainframe when activated in autonomous operation mode, but they lack the authorizations to perform some actions like opening fire without order from the mainframe or a human, which reduces the threat level of hacked dummies. The memories of the dummy can later be merged into the mainframe's neural cloud.<ref name=ModelL>{{cite|gfl|{{doll name|Model L|AR|3}} Nocturnal Executioner costume story}}</ref> Dummies can be remote-controlled by a human operator but this is a very rarely used function.<ref>{{cite|gfl|{{doll name|C96|HG|4|costume=costume1}} Neural Upgrade story 4}}</ref>

One can speculate on what would happen if a mainframe was destroyed before its dummies. Either they would simply collapse when the link is severed, or they could host a backup of the mainframe's Neural Cloud, and continue to operate at lower capacity due to inferior specifications.

There is no officially stated limit to the number of bodies that can be networked with this system. In [[Girls' Frontline]]'s gameplay, the maximum amount of dummied Dolls is five. The [[:File:Login Wallpaper Launch.png|rare illustrations]] showing dummies and secondary media like [[Girls' Frontline: Doll's Song|the manga]] keep within the same amount.

===Neural Cloud===
Neural Cloud (心智云图) (inconsistently capitalized in official sources, also translated "Digi-Mind" in the original text,<ref>[https://m.weibo.cn/status/FEX3AtK5N Weibo - Original announcement of the “Digi-Mind Update System”]</ref><ref>{{cite|ab2|p.291}}</ref> "Neursoul" in some screens of [[Project Neural Cloud]] and "Mindmap" in early fan-translations) is the AI system serving as the mind of T-Dolls. It can be compared to their "soul",<ref>{{cite|pnc|Worldview - Neural Cloud}}</ref> or their operating system. Neural Cloud is a proprietary recording system having the advantage to be transferable to and from a mainframe to protect a T-Doll's memories from being lost if they are destroyed during operations.<ref name=Timeline /> The Doll's memory can then be downloaded into a new body.<ref name=Glossary /> Cases of multiple instances of the same Neural Cloud being downloaded into different bodies are purposefully avoided and occur extremely rarely from hardware malfunction, but the differing individuals can be merged back in such cases.<ref>{{cite|gfl|{{doll name|Type 56|RF|4|costume=costume1}} Neural Upgrade Story}}</ref> Much like ordinary humans, dolls can gain experience in combat, the longer they spend in sorties the better bonded they are with their weapon, on top of tactical knowledge, thus making them more effective at combat. This is why preserving their Neural Cloud is important.<ref name=100Shiki />

Neural Cloud backups are usually made outside of combat since they require massive data transfer, so the Doll will lose their memories from events after the backup. On-the-field backup to portable hardware is a possibility but the storage must be recovered.<ref name=Handbook /> Losing parts of their memories can be distressing to some Dolls,<ref>{{cite|gfl|ct|Safe House, SOP-II goes to great lengths to preserve RO's memories of her time with M4}}</ref><ref>{{cite|gfl|ct|The Last Day, Cx4 Storm argues one's identity relies on uninterrupted stream of memory}}</ref><ref>{{cite|gfl|ct|Defense Outpost 2, 9A-91 preserves her recent memory in a diary}}</ref> but some consider these memories are not truly lost if this period of time is remembered by others,<ref>{{cite|gfl|10-3E| and [[Continuum Turbulence]], Darkest Desire, the Carcano Sisters argue lost memories live through the memories of others}}</ref> make it part of their personality,<ref>{{cite|gfl|ct|Just Kidding, Mk12 explains how she changes her ambitions based on her most recent memories at each backup restore}}</ref><ref>{{cite|gfl|iso|Wolf and Owl I, AK-12 claims she doesn't care about being destroyed as long as there are witnesses to her last stand}}</ref> or even consider it a great chance to be able to be “revived” any number of times while humans cannot once killed.<ref>{{cite|gfl|10-2}}</ref>

However, memories stored at Level III cannot be transferred out of the body<ref>{{cite|gfl|{{doll name|UMP45|SMG|5|costume=costume3}} Neural Upgrade Story 3}}</ref> and the data integrity of a Neural Cloud will slowly decay over time,<ref>{{cite|pnc|[[Python (PNC)]] quotes}}</ref> even faster in case of frequent downloads and gradual repair of the same mainframe body.<ref>{{cite|gfl|{{doll name|Type 56|RF|4|costume=costume1}} Neural Upgrade Story 1, Type 56 momentarily loses sight because of frequent backup damage.}}</ref> Anomalous events causing a cascade of malfunctions in the neural cloud is called a “neural meltdown” (心智解体 or 心智融毁, in some contexts “neural cloud self-destruction” or “melted down”), causing a seizure-like bodily reaction. Meltdowns are usually caused by electronic attacks,<ref name=C72Melt /><ref>{{cite|gfl|sc|E5-1}}</ref><ref>{{cite|gfl|In Polarized Light, 13-4 and UMP45's third Neural Upgrade story, the result of the original [[Parapluie]] virus is described as a meltdown}}</ref> but can be a response to heavy emotional stress.<ref>{{cite|gfl|8-3E}}</ref><ref>{{cite|gfl|9-1N}}</ref><ref>{{cite|gfl|{{doll name|AK-74U|SMG|5|costume=costume1}}'s Lily of the Valley costume story}}</ref><ref name=100Shiki>{{cite|gfl|{{doll name|Type 100|SMG|5|costume=costume1}}'s Treasure Buried Deep Within costume story}}</ref> A meltdown that is not quickly resolved can leave the Doll critically incapacitated<ref name=C72Melt>{{cite|gfl|7-2E|Dreamer describes M4A1's condition at the end of Chapter 7 as a meltdown}}</ref> or completely destroy the data in the neural cloud. This might be an intended effect in order to prevent the capture of a Doll's data.<ref>{{cite|gfl|11-4|[[K]] triggers a neural meltdown of [[Marlohe]] to prevent data capture}}</ref><ref>{{cite|gfl|10-4N|Kar98k prepares to self-destruct her neural cloud}}</ref> A meltdown is automatically triggered for Dolls that try to bypass their limits on attacking humans,<ref>{{cite|gfl|ct|ELID-Infected}}</ref> and it is also used for a Doll's final disposal.<ref>{{cite|gfl|{{doll name|UMP9|SMG|5|costume=costume4}} Neural Upgrade story 2}}</ref>

The rating of a Neural Cloud represents its breadth and depth. Dolls with a higher-rated Neural Cloud better imitate the complexity and range of mental functions of the human mind. Newer Doll models usually benefit from higher-rated Neural Clouds but older models can take a neural upgrade to increase their rating,<ref name=PP19 /> though they can't match the quality of new models.<ref>{{cite|gfl|{{doll name|Galil|AR|4|costume=costume1}} Neural Upgrade Story 1, Kalina explains to Galil she won't be able to match the performances of newer Dolls even with an upgrade.}}</ref>

Regular periods of "sleep" are necessary for Dolls to clear their memory cache.<ref>{{cite|gfl|8-2|{{doll name|M16A1|AR|4}} mentions that Sangvis Ringleaders sleep to clear their cache}}</ref><ref name=RO94>{{cite|gfl|9-4|{{doll name|RO635|SMG|5}} must sleep after overusing her command module.}}</ref><ref>{{cite|gfl|[[Notebook/Operation Mermaid]], {{doll name|Type 88|MG|5|costume=costume2}} Anti-Drowning Accessories costume story}}</ref><ref>{{cite|pnc|[[PNC Story/Symphonic Reprise Nodes]]}}</ref> An overloaded cache will hinder a Doll's processing capacity and cause her to make mistakes or malfunction.<ref>{{cite|gfl|{{doll name|Beretta Model 38|SMG|4|costume=costume1}} Neural Upgrade Story 4, M38 can't operate properly because her previous owner doesn't let her “sleep”.}}</ref> Standard Dolls are not able to dream<ref>{{cite|gfl|8-2E}}</ref> but may involuntarily access old memories,<ref>{{cite|gfl|{{doll name|KSVK|RF|5|costume=costume3}} Neural Upgrade Story 1}}</ref><ref>{{cite|gfl|[[Notebook/Witch's Forest]], {{doll name|F1|SMG|3|costume=costume1}} Dark Sorceress Academy costume story}}</ref><ref>{{cite|pnc|Gastronomic Journey Part 2}}</ref> or suffer from hallucinations as a side-effect of neural cloud instability<ref>{{cite|gfl|{{doll name|GSh-18|HG|4|costume=costume2}} Neural Upgrade Story 4}}</ref> or during self-diagnosis and repair.<ref>{{cite|gfl|[[Notebook/Christmas Eve Express]], {{doll name|G36|AR|4|costume=costume6}}'s Every Child's X'mas Dream costume story}}</ref> A lack of storage space may cause a Doll to not be able to create more memories, causing other malfunctions.<ref name=Hanyang>{{cite|gfl|{{doll name|Hanyang Type 88|RF|4|costume=costume2}} Neural Upgrade Story 2.}}</ref>

The head of a Doll houses critical parts of their neural cloud functions. As a consequence, the upper spine of a Doll is a structural weak point that will prevent all motor functions if severed,<ref>{{cite|gfl|{{doll name|AK-15|AR|6|costume=costume1}} Neural Upgrade Story 3, {{doll name|AK-15|AR|5}} looses all motor functions after {{doll name|AK-12|AR|5}} cuts her upper spine with a knife.}}</ref><ref name=Clotho35>{{cite|pnc|Twilight Requiem - Stage 3-5}}</ref> and critical damage to the head will render a Doll inoperable.<ref>{{cite|gfl|10-3E|[[Yegor]] takes out {{doll name|RO635|SMG|5}} with a headshot at close range.}}</ref> The neural cloud is contained in a dedicated module called the neural core, hosted in the Doll's torso.<ref>{{cite|gfl|13-3E}}</ref><ref name=MG31 /><ref>{{cite|pnc|Gastronomic Journey Stage 5-3}}</ref> This core possesses its own power bank to keep the neural cloud safe for a period of time when it is taken out of the body. Under normal circumstances, extracting the neural core is probably done with specialized tools, but it is also possible to extract it more violently by ripping the T-Doll's body open. However, a neural core is a fragile piece of hardware that is easily damaged.<ref>{{cite|gfl|ct|Chapter 1 Safe House}}</ref> It is still possible to recover some data if a neural core has been damaged or ran out of power.<ref>{{cite|gfl|{{doll name|M4 SOPMOD II|AR|4}} Neural Upgrade Story 2}}</ref> The neural cloud is susceptible to electronic disruption attacks, but these can be countered with signal amplifiers.<ref>{{cite|gfl|fp|E4-9}}</ref>

The equivalent of a neural cloud for a [[Nyto]] is called a Virtual Cognition Image. Their equivalent of a neural meltdown is called a virtual cognition disintegration.<ref>{{cite|gfl|ms|Ariadne’s Clew I}}</ref> [[Ultilife]] created a technology capable of digitizing human consciousness to interface with computers using the same system of levels as a Neural Cloud, though this is an extremely dangerous procedure because any destabilization in the virtual world will impact the body.<ref>[[:File:PNC ARG.jpg|Neural Cloud ARG]]</ref><ref name=NC14D>{{cite|pnc|Dark 1-4}}</ref><ref>{{cite|pnc|5-5}}</ref><ref>{{cite|pnc|[[Zion]] quotes}}</ref>

====Consciousness levels====
There are three consciousness levels for a neural cloud, called Level I, II and III in [[Girls' Frontline]] and Primary, Secondary and Tertiary Layers or Level in [[Project Neural Cloud]].

The first level, or “surface consciousness”,<ref>{{cite|gfl|sg|Splinter Point I}}</ref> is the default state of awareness.

The second level is equivalent to a state of sleep or deep trance where a T-Doll's body freezes in a position and she stops responding to external stimuli. T-Dolls are taken to this level during maintenance<ref>{{cite|gfl|dd|1-1}}</ref> or when performing a level of electronic warfare (EW) where they need to cut control on their body and external sensors to save processing power.<ref name=Singu1A1>{{cite|gfl|sg|1A Stroke Dead Center 1}}</ref> A T-Doll can usually enter and leave Level II at will but some EW attacks can leave a T-Doll's neural cloud stuck at Level II until repaired.<ref>{{cite|gfl|dd|2-4}}</ref> Modules concerning unconscious tasks such as sensory input, motor control and data processing operate on this level.<ref>{{cite|pnc|Worldview - Secondary Level}}</ref> [[Magrasea]] exists on this level.<ref>{{cite|pnc|5-1}}</ref>

The third level stores the base codes and core data of a Doll.<ref>{{cite|pnc|Worldview - Tertiary Level}}</ref> It is equivalent to a T-Doll's subconscious and is reached during heavy maintenance when a T-Doll's control on her body is completely severed and she can't wake up without external assistance.<ref name=45MOD2 /> Dolls whose consciousness sunk to this level are prone to dream-like hallucinations.<ref>{{cite|pnc|5-2 and 5-5}}</ref>

====Neural Upgrade====
Neural Upgrade is a service provided by [[IOP]]<ref>{{cite|gfl|{{doll name|SV-98|RF|4|costume=costume3}} Neural Upgrade Story 3, {{doll name|Colt Revolver|HG|5|costume=costume3}} Neural Upgrade Story 3}}</ref> to overhaul the Neural Cloud of Dolls with older or lower-rated Neural Clouds, increasing their general performance. The upgrade may change the Doll's personality and is usually paired with upgrade of parts or the complete replacement of the mainframe body to increase hardware performances. Dolls often choose to alter their appearance to symbolize their growth and change. Maintenance fees are pricier for upgraded Dolls, however.<ref name=OBR1>{{cite|gfl|{{doll name|OBR|RF|4|costume=costume2}} Neural Upgrade story 1}}</ref>

A Doll can receive an upgrade either by being selected by [[the Commander]] as a reward for good performances and the will to grow past their limits,<ref>{{cite|gfl|{{doll name|FN-49|RF|4|costume=costume2}} Neural Upgrade Story 4, {{doll name|M1918|MG|5|costume=costume4}} Neural Upgrade Story 4, {{doll name|Mosin-Nagant|RF|5|costume=costume2}} Neural Upgrade Story 1, {{doll name|Bren|MG|4|costume=costume1}} Neural Upgrade Story 4, {{doll name|G3|AR|4|costume=costume2}} Neural Upgrade Story 4}}, {{doll name|SV-98|RF|4|costume=costume3}} Neural Upgrade Story 3, {{doll name|Colt Revolver|HG|5|costume=costume3}} Neural Upgrade Story 3, {{doll name|Sten MkII|SMG|4|costume=costume2}} Neural Upgrade Story 4, {{doll name|M14|RF|4|costume=costume2}} Neural Upgrade Story 4, {{doll name|G36|AR|5|costume=costume5}} Neural Upgrade Story 3, {{doll name|AS Val|AR|5|costume=costume2}} Neural Upgrade Story 3, {{doll name|Super SASS|AR|4|costume=costume2}} Neural Upgrade Story 3, {{doll name|PP-19|SMG|5|costume=costume3}} Neural Upgrade Story 1, {{doll name|M1897|SG|4|costume=costume3}} Neural Upgrade Story 2, {{doll name|Galil|AR|4|costume=costume1}} Neural Upgrade Story 1</ref> by submitting an application to be approved,<ref>{{cite|gfl|{{doll name|LWMMG|MG|4|costume=costume2}} Neural Upgrade Story 4, {{doll name|StG44|SMG|4|costume=costume1}} Neural Upgrade Story 3, {{doll name|F1|SMG|4|costume=costume2}} Neural Upgrade Story 3, {{doll name|Beretta Model 38|SMG|4|costume=costume1}} Neural Upgrade 4, {{doll name|C96|HG|4|costume=costume1}} Neural Upgrade 1, {{doll name|XM8|AR|5|costume=costume2}} Neural Upgrade story 4}}</ref> or by paying for the upgrade with their own money.<ref>{{cite|gfl|{{doll name|IDW|SMG|4|costume=costume2}} Neural Upgrade Story 4, {{doll name|MP-446|HG|4|costume=costume3}} Neural Upgrade Story 4, {{doll name|Stechkin|HG|5|costume=costume1}} Neural Upgrade Story 4}}</ref> The upgrades performed on the main characters of the story ([[AR Team]], [[Squad 404]] and [[Task Force DEFY]]) and some other Dolls are ad-hoc modifications rather than an official IOP process.

It should be noted that in [[Girls' Frontline]], the term Neural Upgrade is used rather loosely since some upgradable Dolls only receive an upgrade to their body. For a list of Dolls who received a Neural Upgrade and their circumstances, see [[Griffin & Kryuger#Life at the base]].

====Memory editing====
While editing and deleting Doll memories is regularly used a a plot device, details about the means and risks vary depending on the story:

*In [[Project Neural Cloud]], [[Antonina]] laments that editing Doll memories is commonplace.<ref>{{cite|pnc|Dark 4-4}}</ref>
*[[Arctic Warfare]] introduces selective memory deletion as the mean used by [[Squad 404]] to remains anonymous by deleting the memories of other Dolls after completing their mission.<ref>{{cite|gfl|aw|Homecoming IV}}</ref> In 12-6, SOP-II demonstrates she forgot about working with them during Arctic Warfare.
*In 9-1N, [[the Commander]] refused to delete T91's memories of M16 in order to cure her debilitating melancholy after M16's disappearance.
*Reformatting a Doll causes her to lose all her memories. This is often used by Dolls kidnappers and traffickers.<ref>{{cite|gfl|{{doll name|HK416|AR|6|costume=costume3}} Neural Upgrade Story 3}}</ref>
*Doll memory editing services can be found on the black market, but some practitioners are crooks who instead reformat the Dolls to resell them. Deletion is also not a perfect process and remaining memory fragments can resurface during larger modifications to the neural cloud, such as during neural upgrade.<ref>{{cite|gfl|{{doll name|PPK|HG|4|costume=costume3}} Neural Upgrade Story 3}}</ref>
*{{enemy name|Dreamer|boss}} kept {{enemy name|Destroyer|boss}} docile despite betraying her multiple time by deleting her memories of being betrayed before each backup restore. In Chapter 8-4, Destroyer lacks critical intel to fight because of this process.<ref>{{cite|gfl|5-6| & [[Polarized Light]], Analyzer}}</ref>
*In 13-4, [[William]] remotely encrypted specific memories of M16 so she would not carry [[Lycoris]]'s warning to [[Persica]].
*In [[Dream Theatre]] - Full-Length Play I, it is stated that Dolls can't edit their own memories.
*In {{doll name|LWMMG|HG|2|costume=costume3}}'s My Lie in December costume story, LWMMG deletes some of her own memories.
*It is possible to create an Neural Cloud that is purpose-built to prevent memory modification, making complete reformatting the only option.<ref name=RPK />

===Human behavior and interfacing modules===
Unnecessary but human-like behaviours in T-Dolls are important to reduce the [https://en.wikipedia.org/wiki/Uncanny_valley uncanny valley effect] when they interact with humans for extended periods of time or in high stress environments. These functions, such as eating food and drinking, or simply having a human-like face and expressions, are grouped under the name Uncanny Valley Protocol.<ref name=BF404 /><ref>{{cite|gfl|pr|Falling Star alpha}}</ref> It is unclear if Dolls can get drunk on alcohol because the heat generated by their food-to-power conversion system causes neural cloud malfunctions, or if they are made to imitate humans in this aspect.<ref name=CalicoSkin />

A Doll can easily pass for a human from afar, but they can quickly be differentiated on closer inspection due to their unnaturally perfect skin and facial symmetry.<ref>{{cite|gfl|{{doll name|MG34|MG|2|costume=costume1}}'s Divine Peach Blossom costume story}}</ref> Dolls whose body is not completely covered in bionic skin and instead exposes some ot their mechanical parts are sometimes discriminated against by humans.<ref name=LS5A7>{{cite|gfl|ls|5-α7}}</ref>

Sensory and communication abilities of Dolls are managed independently by dedicated modules and some Dolls models might not include the full range of human capabilities, like vehicle testing Dolls who are not factory-set with a vocal module<ref name=Hanyang /> or basic service Dolls who are not able to display a full range of emotions such as crying<ref>{{cite|gfl|ls|11}}</ref> (though crying Dolls are a common sight in the story). Hearing module sensitivity can be increased to pick up distant sounds during surveillance,<ref>{{cite|gfl|{{doll name|Welrod MkII|HG|6|costume=costume4}} Neural Upgrade Story 1}}</ref> and certain Dolls are outfitted with advanced vision modes, such as {{doll name|M4A1|AR|5|costume=costume1}}'s thermal imaging,<ref>{{cite|gfl|pl|Aperture}}</ref> {{hero name|Chelsea|warrior|2}}'s infrared vision for firefighting purposes,<ref>{{cite|pnc|Crisis Rescue Part 1}}</ref> and the Wolf Eye System installed by [[Shaw]] in {{doll name|AK-12|AR|5}} and {{doll name|AK-15|AR|5}}.<ref name=AK1>{{cite|gfl|{{doll name|AK-15|AR|6|costume=costume1}} Neural Upgrade Story 1}}</ref>

Griffin and Kryuger T-Dolls retain their Emotions Module, which some T-Dolls consider unnecessary because it also enables them to feel various forms of stress.<ref>{{cite|gfl|5-5|{{doll name|M4 SOPMOD II|AR|4}} questions why [[AR Team]] T-Dolls retain their emotions modules.}}</ref><ref name=Veccos1>{{cite|gfl|{{doll name|Vector|SMG|5|costume=costume1}} Kitty Paws costume story}}</ref> These emotions are derived from the Neural Cloud preset seed of the Doll, making them deterministic to some degree, but they are also influenced by the Doll's own experiences during their operational lifetime. Each Doll's unique personality is the sum of their preset and memories.<ref name=RO4 /><ref>{{cite|gfl|[[Bookshelf of Memories]]|Becoming a Star - Priceless Sincerity}}</ref> Most Dolls quickly learn to control the intensity of their preset quirks and biases, but this might be more difficult depending on their life experiences.<ref name=Suomi4>{{cite|gfl|{{doll name|Suomi|SMG|6|costume=costume4}} Neural Upgrade Story 4}}</ref> A Doll's social interaction modules may be geared towards specific kinds of conversational stances depending on their target market.<ref>{{cite|pnc|''Magrasea's Lang Syne'', Vibrato 3}}</ref>

T-Dolls systems emulates physical pain as a self-preservation incentive<ref>{{cite|gfl|{{doll name|UMP45|SMG|4}} Neural Upgrade Story 1}}</ref><ref>{{cite|pnc|Aberrance's Chain, Information Fragment V}}</ref> though this can be disabled,<ref name=Molding /><ref name=Python22 /> and heavy breathing is replicated to provide air cooling for internal components during intense activities.<ref>{{cite|gfl|iso|Wolf and Owl I}}</ref><ref>{{cite|pnc|Twilight Requiem - Stage 4-4}}</ref> They are also equipped with a biological reactions modules to emulate functions of the human body like sneezes, which can be turned off during operations.<ref>{{cite|gfl|[[Far Side of the Sea]]| part 1, {{doll name|MDR|AR|5}} sneezes because she forgot to turn off the adequate module}}</ref> Some Dolls even have food allergies causing belly aches.<ref>{{cite|gfl|11-1E}}</ref>

===Electronic warfare module===
Most T-Dolls can run electronic warfare (EW) tasks, such as hacking into a system or performing counter-hacking at a basic level, but they can't draw much of their computing power for these operations. A dedicated module is necessary for serious EW operations. Electronic warfare directly puts the integrity of the neural cloud at risk in case of countermeasures.

Aside from firewalls, an effective countermeasure to electronic attacks is for a T-Doll to close all her network ports, isolating her from external signals. Only highly modified Dolls can easily use this defense, and it prevents the use of Zener Protocol.<ref>{{cite|gfl|sc|Intangible Sigh I}}</ref>

List of known dolls with/once had EW module installed or are stated to be experienced with EW:
*{{doll name|AK-12|AR|5}}
*{{doll name|AN-94|AR|5}}
*{{doll name|UMP9|SMG|4}}

=== Energy System ===
T-Dolls have primary and emergency power banks and can use their batteries to power external equipment if necessary.<ref>{{cite|gfl|9-2E|{{doll name|RO635|SMG|5}} uses her backup batteries to boost the signal emitter on {{doll name|M16A1|AR|4}}'s equipment case.}}</ref> However, Dolls need updated identification keys to use official IOP charging facilities, forcing illegal Dolls to rely on wiring cars power cells and scavenging for discarded batteries.<ref name=416MOD1>{{cite|gfl|{{doll name|HK416|AR|5}}'s Neural Upgrade story, chapter 1}}</ref> The neural core housing a T-Doll's neural cloud has its own power banks to keep it functional for a period of time even after it has been disconnected from any power source.<ref>{{cite|gfl|ct|{{doll name|M4 SOPMOD II|AR|4}} aims to retrieve a power unit to keep {{doll name|RO635|SMG|5}}'s neural core alive}}</ref> 

T-Dolls can also consume food and drinks (including alcohol<ref name=CalicoSkin />) to generate energy and may enjoy eating<ref>{{cite|gfl|aw|1-3, [[AR Team]] mentions the need for rations and their beneficial effects on morale}}</ref> (saliva is even used in a side-story to identify a Doll),<ref name=ModelL /> but the conversion efficiency to usable power is low, which is why food is not usually used outside of emergency situation.<ref name=BF404>{{cite|gfl|[[Bounty Feast]]|''Hide Behind the Wall!''}}</ref> Regardless of efficiency, G&K Dolls much prefer regular food to the MREs they use during missions.<ref name=PKP2 /> {{doll name|M4 SOPMOD II|AR|4}}, a long-range tracking specialist with long operational efficiency, was able to operate in combat situation without recharging for about 24 hours straight<ref>{{cite|gfl|9-1E}}</ref> while the command-type T-Doll {{doll name|RO635|SMG|5}} could complete a recharge plus cache clearing cycle in about one hour.<ref>{{cite|gfl|9-4}}</ref>

===Body Frame===
{{ThumbSlider|width=300|align=right|list=
{{p|[[File:Delacey base3.png|thumb|A naked Doll frame being worked on by {{hero name|Delacey|medic|3}}, a Doll-maintenance Doll.]]}}

{{p|[[File:Tony hurt.png|thumb|Damaged {{hero name|Tony|warrior|3}}.]]}}
}}
T-Dolls hardware is not affected by air temperature and can function in subzero environments,<ref name=BF404 /> though their joints can freeze in snow storms and their weapons are not as resilient to extreme temperatures.<ref>{{cite|gfl|[[Bounty Feast]]|''A Small Target''}}</ref><ref>{{cite|gfl|12-3}}</ref> T-Dolls can't normally remain immersed in water for long periods of time without [[:File:AN-94 costume1.png|specific equipment]] as their body is not entirely waterproof and water would seep in and they would short-circuit after a period of time.<ref>{{cite|gfl|11-4E}}</ref> Prolonged immersion in sea water is especially damaging due to salt corrosion.<ref name=OBR4>{{cite|gfl|{{doll name|OBR|RF|4|costume=costume2}} Neural Upgrade story 4}}</ref> T-Dolls are shown to be able to immerse for short periods of time with no danger (aside from not knowing how to swim) during the [[Far Side of the Sea]] event, and rain appears to not be dangerous either.<ref>{{cite|gfl|10-2E| and [[Continuum Turbulence]] 1-2}}</ref> {{doll name|ADS|AR|5}} is known to have been purpose-built with better proofing against sea water,<ref name=OBR4 /> and this probably applies to other aquatic-themed Dolls such as {{doll name|SPP-1|HG|4}}.

As a rule of thumb, Machine Gun Dolls have heavier bodies.<ref>{{cite|gfl|LOFT - Eames Chair [[Dorm]] [[Furniture]] description}}</ref> In {{doll name|MG3|MG|4}}'s case, her stouter body frame enabled her to embark more powerful servomotors, while her ample chest housed bigger power units and anti-ballistic gel to protect her neural core.<ref name=MG31>{{cite|gfl|{{doll name|MG3|MG|5|costume=costume4}} Neural Upgrade Story 1}}</ref> Certain models such as the [[Svarog Heavy Industries]] [[Zion|CRAR]] are heavier than normal due to their integrated safety equipment. The bodies of military-grade T-Dolls like M4A1 and [[Task Force DEFY]] are bulletproof for small and medium calibers.<ref>{{cite|gfl|pl|Aperture}}</ref><ref>{{cite|gfl|13-6}}</ref><ref>{{cite|gfl|dr|Animal Chess}}</ref> A Doll's skin emits the same warmth as a human's.<ref>{{cite|gfl|{{doll name|Lewis|MG|5|costume=costume2}} Holy Night Promise costume story}}</ref>

Many Shotgun Dolls have supplementary mechanical limbs protruding from their back to hold their ballistic shield ({{doll name|M870|SG|5}} has a tail but it does not hold her shield), and a similar attachment can be seen on {{hero_name|Rise|Specialist|2}}. Another type of mechanical attachment is the exoskeletons along the legs of some Dolls like {{doll name|UMP45|SMG|4}}, {{doll name|UMP40|SMG|4}}, {{doll name|LWMMG|MG|4|costume=costume2}} or {{doll name|Type 88|MG|5}}. These extra limbs and exoskeletons are nearly always ommitted from alternate artworks, which implies that they are simply attachments rather than a part of the Doll's body. One exception to this is {{hero_name|Delacey|Medic|3}}, whose tail does not appear to be detachable.

===Retirement===
[[File:Gin base3.png|thumb|Wear and tear has worned down the fake skin and revealed the metal underneath the hands and wrists of {{hero_name|Gin|Medic|3}} in this illustration.]]
The average service life of a Doll is 20 years. It can be extended by upgrading the Neural Cloud and swapping bodies.<ref name=PP19>{{cite|gfl|{{doll name|PP-19|SMG|5|costume=costume3}} Neural Upgrade Story 1}}</ref> The oldest known Doll is {{doll name|IDW|SMG|2}}, who was activated at some point between 2056<ref>{{cite|pnc|[[Betty/Profile|Betty's profile]]}}</ref> and 2062, and was still active in 2092.<ref>{{cite|rc|2-2}}</ref>

The privileged relationship between IOP and G&K meant that IOP was willing to take dolls back from them to retire them from combat. These dolls were those who had no more use at G&K, or were found abandoned on the battlefield and brought back. IOP demilitarizes these dolls by taking their Fire Control Core away, before tweaking them and releasing them on the civilian market.<ref name=Glossary /><ref>{{cite|gfl|ct|Chapter 1 Fortunate?}}</ref><ref>{{cite|gfl|Pre-battle prompt Note from [[Kalina]]: “The lost Dolls that you bring back to your base will still be able to work in a comfortable environment, even if they have their cores removed.”}}</ref> They usually end up as waitresses or mine workers.<ref>{{cite|gfl|5-5|M16A1 mentions the fate of retired Griffin T-Dolls}}</ref><ref>{{cite|gfl|{{doll name|Type 4|RF|4}} Cape No. 4 costume story}}</ref>

=== Elite T-Dolls ===
Despite a lot of T-Dolls' comment on their outstanding performances and high rated status, only a few T-Dolls can truly be classified as Elite (精英) T-Dolls. Some elite T-Dolls are not converted from civilian service dolls, they are likely built purely for war and never given a job within the human society, meaning they have very little experience in interacting with humans other than receiving orders. Also likely due to the expense, elite T-Dolls are not manufactured in great numbers.

Capable of solo operation, excelling at covert activities and electronic warfare, it could be argued that members of [[Squad 404]] can also be classified as elite T-Dolls despite being a rogue faction.

==== AR Team ====
Produced by the top ranking research division within I.O.P., [[AR Team]] members are all produced and fine-tuned to optimal combat performance by 16LAB lead by Persica, their solo operation capability renders them as elite T-Dolls. On top of being able to receive commands, and operate without a human commander, each members of AR Team are even capable of operating individually without any commands.

====Task Force DEFY====
Purpose-built for [[Statesec]] special operations, the members of [[Task Force DEFY]] are state-of-the-art T-Dolls with high combat proficiency, with {{doll name|AK-15|AR|5}} in particular being considered “the strongest T-Doll in existence”. However, {{doll name|AK-12|AR|5}} secured her position as team leader by beating AK-15 in a duel. AK-12, {{doll name|AN-94|AR|5}} and {{doll name|RPK-16|MG|5}} are all capable of cyberwarfare, but AK-12 in particular excels at it (though she recognizes Squad 404 is even better).

====Daybreak Squad====
Active during [[World War Three]], [[Daybreak Squad]] achieved great recognition for their abilities, and the two survivors [[SCAR-L|Aliana]] and [[SCAR-H|Amaris]] are considered “legendary T-Dolls”.

==== Other known elite T-Dolls ====
This is a list of Dolls who have been qualified as elites at some point. Since there is no exact performance benchmark to define an elite, all claims that a Doll is an elite should be considered through their feats in battle (for example, you wouldn't take {{doll name|ZiP .22|HG|4}}'s claim to this title seriously).

Prior to enlisting, T-Dolls serving in [[Griffin and Kryuger]] worked various professions within society: {{doll name|AK-74U|SMG|5}} is rumored to have worked in retail prior to G&K service,<ref name="character_setting">Character description on their announcement picture</ref> {{doll name|T-CMS|RF|3}} worked as a kindergarten teacher<ref name="character_setting" /> and {{doll name|PPK|HG|2}} as a private nanny,<ref name=PPK4>{{cite|gfl|{{doll name|PPK|HG|4|costume=costume3}} Neural Upgrade Story 4}}</ref> {{doll name|RMB-93|SG|3}} was an office worker for a financial company,<ref name=RMBCostume>{{cite|gfl|{{doll name|RMB-93|SG|3}} Moonlight Lover Beyond Reach Costume Story}}</ref> {{doll name|TEC-9|HG|3}} worked for a criminal organization,<ref>{{cite|gfl|{{doll name|TEC-9|HG|3}} adjutant quote}}</ref> {{doll name|Thunder|HG|4}} was tortured as part of her job,<ref>{{cite|gfl|{{doll name|Thunder|HG|4}} Black Swan's Dream costume story}}</ref> while {{doll name|S.A.T.8|SG|5}} had the longest known service record : she worked as a part timer convenience store and luxury hotel clerk, animal breeder and in a child nursery.<ref>{{doll name|S.A.T.8|SG|5}}'s artist [https://twitter.com/NINLION/status/1169747597101191169Twitter post, 6 September 2019]</ref>

Different dolls have different exterior appearance, where most takes the appearance of human females ranging from youngs to adults. {{doll name|Python|HG|5}} and {{doll name|PTRD|RF|4}} are examples of senior T-Dolls while {{doll name|Colt Revolver|HG|4}} and {{doll name|MP5|SMG|4}} are considered younger in appearance. Many Dolls sport unnatural hair and eye colors (quite logically, Doll hair does not grow<ref>{{cite|gfl|dr|Ghost Sisters V}}</ref><ref>{{cite|gfl|pr|Endgame Chaos deci}}</ref>). Some Dolls have distinctly inhuman features, like {{doll name|EM-2|AR|4}} and {{doll name|V-PM5|SG|4}}'s ears, or a variety of animal ears on the head or tails which are not depicted as accessories, like {{doll name|IDW|SMG|2}}, {{doll name|KSVK|RF|4}}, {{doll name|ART556|SMG|4}}, {{doll name|P7|HG|4}}, {{doll name|CR-21|AR|4}}, {{doll name|G41|AR|5}}, {{doll name|NS2000|SG|3}} and {{doll name|Type 88|MG|5}}. Some T-Dolls retain scars from previous damage on their bodies like {{doll name|UMP45|SMG|4}}, {{doll name|M16A1|AR|4}}, {{doll name|Thunder|HG|4}} and {{doll name|M6 ASW|SG|5}}.

Dolls with higher-grade bodies will bleed “bionic blood” when receiving external injuries,<ref name=Suomi4 /><ref>{{cite|gfl|{{doll name|AK-15|AR|6|costume=costume1}} Neural Upgrade story 3 (first use of the term “bionic blood”)}}</ref> while lower-grade bodies only show clean cuts. Dolls like {{doll name|AN-94|AR|5}}, {{doll name|EM-2|AR|4}} and {{doll name|KSVK|RF|4}} are bleeding in their damaged illustration. Additionally, hydraulic fluid may leak when the body is heavily damaged.<ref>{{cite|gfl|ms|Möbius Strip, {{doll name|AK-15|AR|5}} leaks hydraulic fluid after her right arm is destroyed.}}</ref>

Doll clothing and fashion of choice varies with their personality, and they wear a great variety of clothes, hair styles, accessories and light body modifications like piercings. Being similarly shaped to humans, they have complete compatibility with clothing designed for humans,<ref>{{cite|gfl|2018's Sweet Oath event described G&K service T-Dolls were hired by wedding outfit tailors and served as clothing models}}</ref> {{NeedSource|Dolls can purchase their clothing of desire on their own or wear any employer issued uniforms.}} Some elite Dolls consider it a demonstration of their skill to be sporting long hair despite its impracticality in combat.<ref>{{cite|pnc|[[Clukay/Quotes|Clukay's Quotes]]}}</ref> Some Dolls have drone or animal companions, like {{doll name|FO-12|SG|5}}, {{doll name|DP-12|SG|5}}, {{doll name|M1897|SG|3}}, {{doll name|TAC-50|RF|5}},  {{doll name|MG36|MG|5}},  {{doll name|Ballista|RF|5}}, {{doll name|FAL|AR|5}}, {{doll name|Honey Badger|SMG|4}}, {{doll name|M500|SG|3}}, {{doll name|P226|HG|3}}, {{doll name|MAG-7|SG|4}} and {{doll name|Steyr Scout|RF|3}}.

Dolls come with different personality settings and hobbies, which are factory set<ref>{{cite|gfl|{{doll name|UMP45|SMG|4}} Neural Upgrade story 1, UMP45 commenting on her depression being a factory default personality setting}}</ref> and usually cannot be overwritten,<ref name="CT_E1_Cx4">{{cite|gfl|ct|E1, {{doll name|Cx4 Storm|SMG|4}}'s conversation with SOP II regarding her tobacco packaging collection}}</ref> though there are cases of Dolls concealing their true personality like {{doll name|Negev|MG|5}}<ref>{{cite|gfl|7-4N}}</ref> or completely adopting a persona with the help of memory editing like {{doll name|PPK|HG|2}}.<ref name=PPK4 />

Doll hobbies varies greatly between dolls:
*Some hobbies are collection based, such as {{doll name|SV-98|RF|3}}'s badge collection<ref name="artist_comment">Commented on by T-Doll's artist</ref>, {{doll name|SVD|RF|4}}'s sticker collection<ref name="artist_comment" /> and {{doll name|M4 SOPMOD II|AR|4}}'s Sangvis Ferri android body parts collection.<ref name="character_setting" /><ref>{{cite|gfl|4-2E|{{doll name|M4 SOPMOD II|AR|4}} excitedly presents the latest piece of her collection to [[the Commander]]}}</ref>
*Some hobbies are activity based, such as {{doll name|TAR-21|AR|4}}'s interest in tea ceremony, flower arranging, kendo and ballet<ref name="character_quotes">T-Doll quotes</ref>, {{doll name|Sten MkII|SMG|3}}'s baking hobby<ref name="character_quotes"></ref> and {{doll name|TMP|SMG|3}}'s interest in computing electronics.<ref>{{cite|gfl|[[Glory Day]]|E1, where {{doll name|TMP|SMG|3}} shows her interests and demonstrate ability in working with electronic gadgets}}</ref>
*Other hobbies are consumption based, such as {{doll name|FNC|AR|3}}'s love for sweets and chocolates,<ref name="character_setting" /> {{doll name|A-91|AR|4}}'s excessive vodka consumption,<ref name="character_setting" /> and {{doll name|T91|AR|5}}'s obsession with milk tea.<ref name="character_quotes"></ref> There is a running joke in the game about T-Dolls having a universal love for ice cream.<ref>{{cite|gfl|Intermediate Training Data and Memory Fragment item descriptions ; Payday - Anti-Theft Trap [[Dorm]] [[Furniture]] description ; {{doll name|GSh-18|HG|3}} Neural Upgrade story 2}}</ref>
**Since T-Dolls have no need to rely on organic food to survive, most consumption based hobbies are essentially pointless.<ref group=note>There is conflicting information concerning Dolls and tobacco smoking. In [[Continuum Turbulence]] E1 “Fortunate?”, {{doll name|Cx4 Storm|SMG|4}} believes smoking is dangerous for Dolls. In [[PNC Events#Quenching Operation|Quenching Operation]], [[Python (PNC)|Python]] regularly smokes cigarettes, while his designers consider that Dolls can't smoke in the [[PNC Story/Quenching Operation/Nodes#Challenge Stage|Challenge Stage nodes]].</ref>
**T-Dolls are able to become intoxicated when they consume alcohol.<ref>{{cite|gfl|7-4E|the voice of {{doll name|RO635|SMG|5}} is mumbly during her report because she has been drinking with {{doll name|M16A1|AR|4}}}}</ref>
**Conversely, some T-Dolls have a distaste for some foods, like SRS who considers herself a vegetarian due to hating the taste and smell of meat.<ref name="character_setting" />

I.O.P. is capable of producing T-Dolls merely from data description of a human, achieving pinpoint precision on all exterior features and flawlessly mimicking the personality. Every member of Schicksal Valkyrja had their data collected by I.O.P. and T-Dolls flawlessly resembling themselves were left behind when they departed from the world.<ref>{{cite|gfl|[[Hitoribocchi]]}}</ref> [[Gray]] had a Doll replica of [[Minor Characters#Eugene Rugosa|Lucas Rugosa]] made long after his death.<ref>{{cite|gfl|ls|35-R3}}</ref> It is however illegal to make a doll resembling an existing human<ref>{{cite|gfl|[[Butterfly in a Cocoon]]|Reflection}}</ref> after one originally created for entertainment was used in a political crime. Secret services still make use of convincing and expensive Dolls doubles of their agents to act as decoys.<ref>{{cite|gfl|11-5|[[K]] uses a Doll double to escape a [[Paradeus]] attack}}</ref>

=== Prosthetic limbs ===
Most T-Dolls designs in game have normal human like limbs. There are however a few with mechanical limbs instead of normal human-like limbs. As most of the designs are left to artists' discretion, these peculiarities are not always explained in the story. The earliest examples of dolls with mechanical limbs are {{doll name|M4 SOPMOD II|AR|4}} (SOP-II) and {{doll name|G41|AR|5}}:
*SOP-II's mechanical arms are in fact of Sangvis Ferri design. To demonstrate the modularity of the rifle she represents, SOP-II is able to use body parts from other manufacturers. During [[Continuum Turbulence]], she demonstrated the ability to repair herself with spare parts scrounged from the battlefield.
*G41 on the other hand never had any form of story explanation for her mechanical arms. [[Artist:NS]] did not comment on the design. However, her costume Beach Punk 2064 uses human-like arms.
**Other Dolls with mechanical limbs like {{doll name|M4A1|AR|4}} (right hand), {{doll name|JS 9|SMG|5}} (arms), {{doll name|Type 79|SMG|5}} (right arm), {{doll name|Type 88|MG|5}} (legs), {{doll name|UMP45|SMG|5|costume=costume3}} (right arm) and {{doll name|Ribeyrolles|AR|5|costume=costume1}} (legs) have also been alternatively depicted with human-like limbs.
*{{doll name|AR-18|AR|5}}'s mechanical legs are commented on negatively by humans during the story<ref name=LS5A7 /> (her left arm is also mechanical).

Artist [[Artist:小吃|小吃]] (Chichi), who contributed to the roster of Dolls with mechanical limbs with {{doll name|CZ52|HG|3}} and {{doll name|ADS|AR|5}}, boldly introduced the concept of 'synthetic flesh' covering the bodies of T-Dolls in her artist canon with ADS' character design sheet she posted on Twitter. It took several years for [[MICA Team]] to introduce a related concept in the core canon with bionic skin in [[Longitudinal Strain]].
