| weaponinfo = The Auto Assault-12 (AA-12), originally designed and known as the Atchisson Assault Shotgun, is a an automatic combat shotgun developed in 1972 by American firearms designer Maxwell Atchisson. The most prominent feature is reduced recoil. The current version of the weapon, introduced in 2005 version has been , was developed over a period of 18 years since following the patent was being sold to Military Police Systems, Inc. The original design was the basis of several later weapons, including the USAS-12 combat shotgun. The weapon is fully automatic only<ref name = "aa12 wiki">[https://en.

=== InOne of the major modifications made to the Atchisson design was switching the gun from a blowback action to a gas-game ===operated action with a locked breech. This change is the reason behind one of the AA-12's most prominent design features, that being its surprisingly light recoil for a 12-gauge shotgun. When a round is fired, the weapon's proprietary gas system absorbs around 80 percent of the recoil. An additional recoil spring absorbs another 10 percent, meaning that the shooter will only feel around 10 percent of the recoil one would expect from such a cartridge. This low recoil is especially helpful given the weapon is designed to be fired in full auto, helping the shooter maintain accuracy.

The AA-12 fires from an open bolt, which is uncommon for an automatic shotgun, and is a style of operation more commonly seen in submachine guns and heavy/squad-level machine guns. This, combined with the weapon's heavy use of stainless steel and large clearances for fouling, means that the AA-12 is exceptionally reliable. MPS have stated that the weapon requires little to no cleaning or lubrication, and that cleaning is only required after 10,000 rounds. In 2004, around 10 AA-12 shotguns were produced for testing by the United States Marine Corps. Around the same time, MPS would team up with the Special Cartridge Company based out of London to combine the gun with the FRAG-12 High-Explosive cartridge. This specialized shotgun cartridge fired a slug that contained a small amount of high explosives in the tip, and was designed for breeching intermediate barriers, defeating light vehicles, and remote detonating IEDs. Four folding fins spring out after the slug leaves the muzzle, stabilizing the round in flight. The FRAG-12 has a maximum range of around 200 meters (660 ft), with the explosives arming at around 3 meters (9.8 ft) and detonating on impact.<ref name = "frag12 wiki">[https://en.wikipedia.org/wiki/FRAG-12 Wikipedia article on the FRAG-12 specialized cartridge]</ref> Pairing the AA-12 with the FRAG-12 round allowed the weapon to serve as a multipurpose system, and it was hoped that this would improve the weapon's chances of being adopted by the US military. Ultimately, the AA-12 would not be adopted by the Marines. | min_dmg= ?12

*In-game, AA-12's firing animation shows her weapon having quite a lot of recoil. The real life AA-12 has remarkably low recoil due to its gas-operated closed breech action and recoil spring.*AA-12 is listed in the pre-release [[:File:NC ASST Report 2060.jpg| references =Griffin transfer file]] from [[Project Neural Cloud]] under the name Lind (Doll model redacted). While she is not currently a playable unit in this game, she did appear as an NPC.|}}
