Girls' Frontline Setting Exploration: G&K Combat Forces

Submit Feedback or Error


The primary force of G&K is Tactical Dolls (T-dolls). These forces consist of both purpose-made T-Dolls meant for PMC, police, or other armed work, and civilian Autonomous Dolls (A-dolls) converted to T-Dolls via installation of a Fire Control Core (FCC), an Imprint to a pre-WW3 weapon, and appropriate fire and posture control software. An FCC houses all combat related data and software and removal of the FCC effectively demilitarizes a Doll. T-Dolls are all physically superior to humans, boasting enhanced strength, speed, and cognitive processing.

A T-Doll echelon within G&K can consist of anywhere between one and five T-Dolls. A Team Leader is designated by a Commander and a Vice Leader may be chosen by the lead T-Doll if desired. T-Dolls may request to switch teams if there are compatibility issues, but the final verdict lay with a Commander.

For operations with sensitive information, G&K may partially or completely erase the memories of the operation for the T-Dolls involved.

Elite T-Dolls

T-Dolls can be designated as ‘Elite’ and the title is not clearly defined in-game. However, one thing is clear: their performance both in and out of combat exceeds other T-Dolls. They are the best the company has to offer.

Known Elite G&K T-Dolls:

  • Welrod

  • M870

  • M82A1

  • PKP

  • Negev

  • WA2000

  • Kar98k

  • NTW-20

  • DSR-50

  • Thompson

  • OTs-14

Known Elite T-Dolls of other affiliation:

  • Anti-Rain Team (M4A1, M16A1, ST AR-15, SOPMOD II, RO635)

  • M1887

  • Team DEFY (AK-12, AN-94, RPK-16, AK-15)

  • HK416

Justice must be strong.

Justice is only justice because it is strong.

Therefore, someone who defends justice like me must certainly be strong.

Command Module

A Command Module can be installed in experienced T-Dolls. This allows them to process battle conditions and devise combat plans at a higher efficiency, as well as directly issue orders to T-Dolls both within and outside of their designated echelon in the event of cut-off communications with the Field Commander. Due to the heavy processing load, not every T-doll is installed with this module, and it is only authorized in select operations.

Neural Cloud

The Neural Cloud enables T-Dolls to backup memory and combat records, allowing them to gain experience even if destroyed in combat. It has been shown that the more experience and memories a T-Doll is able to retain, the more effective they are, and the more they grow as an individual beyond their programming. However, memory backups can not be done in real-time, and require connection to the designated G&K server. On-site backups can be done through manually written memos, portable storage disks, or compressed video and audio files within a T-Doll’s Digimind. If a T-Doll is destroyed in combat, but their Core is still intact, it may be possible to recover memories even if a backup was not performed, provided the Core’s emergency power supply has not run out before retrieval.

Dummy Links

T-Dolls can multiply their combat potential through the use of ‘Dummy Links’. This system enables T-Dolls to control Dolls known as ‘Dummies’ - Frames lacking their own AI programming, but possessing the same combat ability as the ‘Mainframe’. A Dummy’s actions can be controlled in unison or in variance of the Mainframe and control can be transferred to another T-Doll’s authority on the spot.

Command Compliance

Any Doll, in general, must comply with any command given by a human. T-Dolls employed by G&K are also installed with additional programming to be loyal to the company. This may influence a T-Dolls behavior to rethink and cease behavior that may negatively affect the company. Attempting to defy an order may result in Digimind structural damage.

A recurring issue with this baseline programming of Dolls is that criminal elements have taken advantage of company T-Dolls on more than one occasion. G&K technicians are aware of the issue, and are working on a solution.


Fairies are an old, abandoned 90Wish drone project revived and modified by Persica for G&K’s usage. She is responsible for developing the base AI and function of each drone, but the AI itself develops its own personality and personal image. They are developed with a command structure based on SF’s OGAS protocol network - a top-down tree shaped network.

Neural Upgrade

Otherwise known as Digimind Upgrade, these modifications are upgrades performed on a T-Doll to increase performance. A proposal must be made by anyone, even a Doll may submit a proposal for another Doll, and submit it to the Commander for approval. What specifically gets upgraded differs for each Doll. T-Dolls may receive a brand new frame altogether, have adjustments made to the Digimind to increase cognition, or receive adjustments and software to use new equipment.

These modifications are a choice and can be declined unless vital to a T-Doll’s continued operation. The upgrades are not free and the payment comes out of a Doll’s personal funds. G&K may sponsor a modification if it is required in order to keep a T-Doll functioning properly.

Heavy Ordnance Corps

Heavy Ordnance Corps (HOCs) are a new and highly illegal development made by Persica through research into Sangvis Ferri technology and investment from Havier, the CEO of IOP. HOCs are a team of T-Dolls imprinted to a single heavy weapon. Their new, and unique imprint technology enables them to function as a single cohesive unit while operating the platform.
