Editing T-Doll

The playable individual units in Girls Frontline are named 'T-Doll', this article's contents are based on 'Girl's Frontline Griffin confidential file' written by the producer Yuzhong, the official edition art book of the game 'The Art of Girls' Frontline Vol.1 - Until The Stars', or based on in-game story/dialogues.

== Definition ==
T-Doll stands for Tactical Doll, all in game playable T-Doll units are second generation T-Dolls. T-Dolls are humanoid shaped Androids, who are both sentient and sapient, bodily system operation are entirely mechanized.

== Development and history ==
=== Production skeletal robotics ===
:'''Prior to AD 2033'''
The advancement into robotics and automation are purely for the sake of faster, easier industrial process. Facility mounted and powered, one well placed robotics and automatons effectively replaced tens if not hundreds of human workers, at a lower cost and brings about greater efficiency. These strangely shaped industrial automatons advanced humanity's industrial capability by a fair margin and set the foundation stone for the development of more sophisticated robotics<ref name="p15intro">Girl's Frontline Griffin confidential file Page 15, introduction paragraph</ref>.

:'''AD 2033'''
Predecessor of T-Doll dates back to AD 2033, they are simply labelled as Skeletal Automatons, instead of Androids they are closer related to automation robotics, the very phrase 'Doll' itself also did not occur until a later date. Instead of being attached to a facility, they were designed for standalone independent field works. Specification for these automatons include:
*Strong body structure for hard labour
*Long independent operating time up to six hours, no longer than four hours of recharge time
*Modular design, able to easily mount and dismount different tools for different tasks, high common parts between machines to save repair and maintenance costs
*Compatible AI system, a newly designed AI system that can easily adapt to different tasks and tools, usually by the means of running different software
Such strict specification at the time was a great challenge for the development teams<ref name="p15c1">Girl's Frontline Griffin confidential file Page 17-18, chapter: The Age of Second Generation Tactical Dolls</ref>.

:'''AD 2035-2037'''
The first concept of 'Doll' occurred around 2035 to 2037. After the first companies made their fame and fortune from these industrialized automatons, they attracted interest from the military, soon the development of automaton for war initiated. Leihart General Manufacturing developed their first 'Doll' type automatons for Pan-European Military Union Assault Artillery vehicles. The Dolls followed the specifications of humanoid-shaped to fit easily in the vehicles, compatible with adaptable AI from Leihart's initial prototypes<ref name="p15c1"></ref>.

:'''AD 2041'''
Applications for the humanoid Dolls were quickly found in both military and civilian sectors, and a plethora of upgrades upon the original models were quickly developed by military and civilian companies alike. Among these were sensor upgrades, power management improvements, and improved AI. Before too long, the developments of these civilian companies had caught the attention of General Carter of the Military Union, resulting in the consolidation of two major companies into the Important Operation Prototype Manufacturing Company, or [[I.O.P.]]<ref name="p15c1"></ref>.

By the present in-game time, 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 name="honkai_collab">Story described during event [[Hitoribocchi]]</ref>

== Appearance and behaviour ==
By the end of the third world war and the calamity of collapse particles, world population had reached an all time low, humans began to run short on the one vital resources they never thought they'd run out: Manpower. Without the sheer population backing up, society itself cannot function, civilian service dolls were widely introduced to the human society to fill the roles left open by former residents. By the latest generation of service dolls, their exterior appearances are essentially identical to that of humans, which helped integrating them into the society. Every model of civilian service dolls are fitted with emotion modules, allowing them to interact with humans closely, combined with the detailed manuals provided, almost any humans can employ the service of service dolls without issue.

Majority of I.O.P. produced T-Dolls are converted models of their civilian service dolls, dolls themselves can enlist for service in G&K, after a quick installation of related modules and issued a weapon, they are sortie ready. Prior to enlisting, dolls comes from all professions of jobs within the society, {{doll name|AK-74U|SMG|5}} worked in retail prior to G&K service<ref name="character_setting">T-Doll character settings</ref>, {{doll name|SRS|RF|5}} was likely part of an education profession, {{doll name|RMB-93|SG|3}} was likely an office worker, while {{doll name|S.A.T.8|SG|5}} had the longest known service record, worked as a part timer from convenience stores, to luxury hotels, to animal breeders and then in child nursery programs.

Service dolls are considered ductile and obedient in nature, it would prove impossible for dolls to disobey or defy human commands as instruction sets were written at the very fundamental levels of their Digi-mind, they are programmed to follow human instructions and can never actively cause harm to a human being, any attempts will result in Digi-mind structural damage.<ref name="CT_E3_AK12">[[Continuum Turbulence]] E3, Digi-mind instability occurred within AK-12 after holding her own commander at gunpoint.</ref>

Different dolls have different exterior appearance, where most takes the appearance of human females around the age 13 to 17, with a few models appear significantly more senior than the others, while some are more junior. {{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. Doll clothing and fashion of choice varies with their personality, being similarly shaped to humans, they have  {{Tooltip|complete compatibility with clothing designed for humans|2018's Sweet Oath event described G&K service T-Dolls were hired by wedding outfit tailors and served as clothing models}}, dolls can purchase their clothing of desire on their own or wear any employer issued uniforms.

Dolls comes with different personality settings and hobbies, it would appear the hobbies and personalities are factory set<ref name="modication_story_UMP45">UMP45 modification story stage 1, UMP45 commenting on her automated depression is a factory default personal setting</ref> and usually cannot be overwritten<ref name="CT_E1_Cx4">Continuum Turbulence E1, Cx4 Storm's conversation with SOP II regarding her tobacco packaging collection</ref>. Though there are exceptional cases where after a series of events and/or newly installed modules, T-Dolls of ductile nature became more aggressive and vengeful<ref name="Singularity_E1_M4A1">Singularity operation hour 1750, M4A1's behaviour change prior to and after undergoing modifications.</ref>.

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 by T-Doll's artist</ref>, {{doll name|SVD|RF|4}}'s sticker collection<ref name="artist_comment"></ref> and {{doll name|M4 SOPMOD II|AR|4}}'s Ferri android body parts collection<ref name="character_setting"></ref><ref name="story">As described in various section of the game's main story</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 name="Glory_day_E1_TMP">Glory Day event E1, where TMP 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"></ref><ref name="story"></ref>, {{doll name|A-91|AR|4}}'s excessive vodka consumption<ref name="character_setting"></ref><ref name="story"></ref>, and {{doll name|T91|AR|5}}'s obsession with milk tea<ref name="character_quotes"></ref>.
**It is worth noting that, since T-Dolls cannot use organic food as a source of energy income, most consumption based hobbies are essentially pointless, consumption of some human commodities such as tobacco is actually lethal to T-Dolls<ref name="CT_E1_Cx4"></ref>.
**A-91 is able to become intoxicated, it is unknown how consuming alcoholic beverages can effect A-91's mechanical body the same way it effect a normal human's biological body.

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.

== Digi-Mind, modules and compatible systems ==
=== ASST system, weapons and Fire-Control Core ===
ASST stands for Advance Statistic Session Tool, such system is developed based on Persica's personal research dubbed as 'Etching' theory. 'Etching' allows two objects to establish special connections, further development of 'Etching' would be 'Branding', Persica later on renamed 'Branding' to ASST. ASST allows a T-Doll to establish greater connection to their weapons than any other software allows<ref name="artbook_p128">The Art of Girls' Frontline Vol.1, Worldview and Concept Design, page 128</ref>, to a degree where they can practically bond with their weapon, it is also said as the dolls studies the history of their weapon of choice, they can achieve higher affinity and greater efficiency<ref name="modication_story_Mosin">Mosin-Nagant modification story stage 2, where Mosin comments on studying of her weapon's history</ref>.
 
After the world war, high grade weaponry are supplied exclusively to military and banned from civilian market, with ASST system being developed by Persica of 16LAB, I.O.P. turned their eyes on older ballistic type projectile firearm weapons. Major benefit of using modified civilian service dolls with outdated weapon is the significantly lower cost, service dolls cost significantly less to repair and maintain than military grade androids<ref name="p15c1"></ref>, as well as the older model ballistic weapons can also be obtained at a low price likely from the war scavengers. One can obtain the similar level of combat efficiency at a much lower cost.

By installing Fire-Control Cores, civilian service dolls gained the knowledge to operate firearms, by installing ASST system their combat efficiency improved to a point where they can rival military grade combat androids. Fire-Control Cores takes 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">Deep Dive E2, UMP40 mentioned her low-grade Fire-Control Core to UMP45</ref>.

By the end of event [[Arctic Warfare]], G&K had captured a Ringleader model of Sangvis Ferri dubbed as 'Architect', Architect is held with 16LAB after surrendering to G&K forces, and cooperated with 16LAB studies. A further development of ASST system was finalized after integrating Sangvis Ferri technology of heavy weaponry operation<ref name="CT_E3_Persica">Continuum Turbulence E3, Hartwell and Persica's dialogue regarding the studying of Architect and the research outcome</ref>. Heavy Ordnance Corp (abbreviate as HOC) units are fitted with a more effective ASST system, which allows them to operate heavy ordnance weapons. However it is likely due to the sheer build quality of dolls, I.O.P. made civilian dolls does not have the physical processing capability of Sangvis Ferri made Ringleader grade androids, heavy weaponry are often operated by a group of three or four similar model T-Dolls, each assigned a task within the team, such as the spotter, weapon operator, weapon loader and/or guard (Some HOC units operates without a guard).

=== Digi-Mind ===

=== Dummy linking ===
T-Dolls can multiply their combat efficiency through 'Dummy-Links', T-Doll can subjugate same (or similar) model T-Dolls and use them as additional combat units, the subjugated dolls are known as 'Dummies' while the T-Doll is known now as the 'Mainframe'. Dummies have the same combat ability as the mainframe, it however does not have complex calculation capability, it is only able to receive and execute orders given from the mainframe<ref name="artbook_p128"></ref>.

As long as the mainframe is not harmed, the T-Doll can operate a small squadron of 'herself' and multiply combat effectiveness, it is likely the dummies can transmit information back to the mainframe, in a sense the mainframe walks in many different bodies.

Either the story nor the lore books had commented on what happens if a mainframe was destroyed while dummy link is active, the following two are merely speculations:
*Result A: Mainframe destruction result in doll death on the field, all remaining linked dummy collapse due to the loss of their command unit regardless of their self conditions, doll wakes up in back up body at the HQ with their last uploaded Digi-mind files.
*Result B: Mainframe destruction result in mainframe consciousness transfer into a remaining linked dummy, the dummy becomes the new mainframe and houses the doll's consciousness, compatibility issue is not present due to dummy and mainframe being the same model. Process repeats until the final dummy becomes the mainframe and undergo destruction for the last time, doll wakes up in back up body at the HQ with their last uploaded Digi-mind files.

=== Others ===
'''Emotion module'''

I.O.P. produced service dolls retained their emotion modules even after entering service with G&K, likely for an enhanced user experience for human personals within the private military contractor.

'''Command module/Command protocols'''

T-Dolls can install command modules which allows them to replace the role of a human commander, with a command module installed to the leader of an echelon, the group of dolls can function as a independent task force carrying out combat/reconnaissance operations without a human commander directly overseeing them. Alternatively, dolls with command module installed can simply be stationed at a command post and oversee operations like a human commander.

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|UMP45|SMG|4}} (Leader of Task force 404, UMP45 utilizes her command module to guide the task force in and out of danger)
*{{doll name|UMP40|SMG|4}} (As observed during Butterfly Event)
*{{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)

Installation of command protocol can also enable a T-doll to command other dolls without the need to install a separate module, additionally the protocol allows the doll to {{Tooltip|spawn simulated friendly echelons|Glory Day event story where such ability is demonstrated by K2}} in combat simulations/cyber space. However command ability is limited to only her echelon and it has an {{Tooltip|expiration date|Glory Day event story where K2 comments on her command protocol expiration is imminent}}.

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 of 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 of having command protocol)
*{{doll name|Welrod|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 of having command protocol)

'''Electronic warfare module'''
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|UMP-9|SMG|4}}
*{{doll name|UMP-45|SMG|4}}
*{{doll name|UMP-40|SMG|4}}
*{{doll name|RO635|SMG|5}}

List of dolls who have participated in EW despite lack of module/inexperience: 
*{{doll name|AEK-999|MG|4}}
*{{doll name|M950A|HG|5}}
*{{doll name|Thunder|HG|4}}
*{{doll name|K2|AR|5}}
*{{doll name|TMP|SMG|3}}
*{{doll name|G11|AR|5}}
*{{doll name|HK 416|AR|5}}

List of dolls stated to have no EW module: 
*{{doll name|Welrod|HG|5}} 

'''Anti-Human protocol'''

As a private military contractor company, some of G&K's contract involves peace keeping within human society, when using dolls to combat human suspects, they can enable Anti-Human protocols within the T-Dolls and enable them to apprehend human suspects without issue, overriding one of their fundamental rules written within their Digi-mind. One of such event took place during {{Tooltip|an attack on a civilian opera theatre|2017's Opera Princes event}}, with super-human physique, reflexes and combat experience, group of selected G&K T-Dolls made short work of the criminal organization.

List of known dolls with/once given/speculated to have been given Anti-Human protocols:
*{{doll name|Thompson|SMG|5}} defeated a number of criminals in melee combat and fired off magazines during the criminal pursuit operation.
*{{doll name|PKP|MG|5}} was given patrol duty near the opera theatre, as an active support unit, she received the protocol.
*{{doll name|Contender|HG|5}} as the first contact and response unit, she received the protocol.
*{{doll name|G36|AR|4}} was assigned the duty of guarding and inspection, she received the protocol.
*{{doll name|MG5|MG|5}} was not part of the theatre defense but a part of the follow up sweeping operation, to combat the remnant group, she received the protocol.

== Doll Operation ==
=== Energy System ===
T-Dolls can consume food for energy, and are programmed with their own tastes in cuisine, but can also eat T-Doll MREs (though, they reportedly don't taste very good). Alternatively, recharging can be done by {{Tooltip|stationary power sockets|Chapter 9E story, RO635 and SOP II engaged in conversation while waiting for themselves to finish recharge}}, or by {{Tooltip|mobile power units|CT campaign, where SOP II aims to retrieve a mobile power unit supplied by G&K usable by T-Dolls}}.

=== Command Input ===
Typically T-Dolls are commanded by a human commander for detailed combat operations, dolls are {{Tooltip|unable to fight|Suggested in various part of the game story}} unless they are constantly given commands, simpler tasks such as base patrol and logistic supports can be performed unsupervised.

T-Dolls with a command module or given temporal command protocols can replace the role of a human commander, such groups are able to {{Tooltip|operate on their own|Glory Day event story describes K2's squadron being able to operate without a human commander}} indefinitely or until their command protocol expires. 

T-Dolls can teach a human on how to command T-Doll echelons in emergency situations, however despite that adjutant T-Dolls knowing how to command doll echelons to a degree where {{Tooltip|they can instruct humans|Hitoribocchi event chapter 1, where Kiana is tutored by PP-90 on T-doll commanding operations}}, they are still unable to operate the command panel themselves without a command protocol.

== 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 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, some are likely to be the only one of her kind.

{{Spoiler}}

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

=== AK-12 and AN-94 ===
Both original members of DEFY were built to meet the specifications of National Security Bureau, both AK-12 and {{doll name|AN-94|AR|5}} demonstrates superior combat performance as T-Dolls. In additional to physical combat, they also excel at electronic warfare, both are capable of rapid database hacking and infiltration, AK-12 is even able to {{Tooltip|subjugate|Complete subjugation of abandoned military androids and use them as additional combat force, as demonstrated multiple times by AK-12 through out both singularity and CT campaign. AN-94 can also subjugate abandoned units but cannot use them as combat force, only as additional processing units}} military grade androids.

=== Other known elite T-Dolls ===
*{{doll name|M1887|SG|5}} operated alone atop the snowy mountain during the event Arctic Warfare until her meeting with the AR Team, she is likely an elite T-Doll chosen to operate in that region.
*DSR-50 was recognized as an elite T-Doll by UMP45 during the event of Deep Dive, UMP45 commented stating that as by unleashing DSR-50, they could easily defeat the rampaging Garm unit.
*{{doll name|M82A1|RF|5}} and {{doll name|M870|SG|5}} are both introduced during the CT campaign, they are classified as elite T-Dolls, but due to their behaviour and personality nature, they do not quite fit the crowd, hence their existence were kept quiet until after the event of Sector S09 event.
*Prior to her service in 404, {{doll name|HK416|AR|5}} was an elite T-Doll served G&K, however it was long ago, dated even before the new Commander was enlisted, only a few T-Dolls remembered her exploits in the present day.
