Girls Frontline

Faction "SVLK-14 BV-1".
This is a faction of puppets led by SVLK-14 BV-1. Nothing is known about this faction or SVLK-14 BV-1 itself, other than its citizens being nothing but puppets. But it is said to be home to the most dangerous and unknown group of puppets—namely, Squad AK. Squad AK consists of five puppets.
AK-47 is the oldest model in the squad. She wields the AK-47 weapon expertly. She's the oldest, but also the most experienced and battle-hardened model, albeit with a rough edge. Her experience has been passed on to the other dolls in the squad.
MP5 is the fastest and most agile model in the squad. She wields the MP5 weapon. She's playful, cheerful, and a little crazy in battle, always choosing the most brutal methods to eliminate enemies, catching them off guard. But she's always cheerful and optimistic in the squad, despite her methods of eliminating opponents.
Barrett M82 — The largest and most powerful model in the squad. Wields the Barrett M82 sniper rifle. Capable of penetrating light armored vehicles or a row of dolls. The quietest of the squad. But she's always close to her comrades and never refuses help, even when it's unsolicited, and everyone in the squad appreciates that.
The SCAR-H is the most stable and powerful weapon in the squad after the Barrett M82. She wields a SCAR-H assault rifle. She serves as long-range support against heavy dummies, which MP5 rounds can't penetrate. She is a realist and a pragmatist. She was the squad leader before AK-47's arrival. She respects AK-47 for her skills and the dark history that only she knows, and values ​​her highly as both a comrade and a friend.

1. The Great Betrayal: The PMC was just a front
   The finale's biggest shock is the reveal of the high command's hand. It turns out that Count Griffin (one of the founders of the Griffin & Kruger PMC, for which the player worked) was a spy and puppeteer all along. He used the Commander, the PMC, and all the T-Dolls solely as pawns. His true goal was to gain control of the mad scientist William (the creator of Paradeus) and his research into alien relics, using it to create the United Nations Coalition of Rossartism (URNC), a new totalitarian world government.
2. William and Paradeus's finale
   The Commander and the remaining puppets loyal to him stage a final hunt for the Paradeus organization. During a brutal confrontation, the Commander manages to corner William and finish him off, halting the production of the horrific biomechanical hybrids. However, the victory proves bittersweet: the Commander realizes that William is backed by new political giants, against whom the PMC is powerless.

The story of the M16A1 clearly illustrates the game's main theme: dolls are capable of absolute self-sacrifice, contrary to their programming.

3. True Motive: M4A1 Defense
   Later in the story, it becomes clear that the M16A1's defection to the enemy wasn't pure madness. She learns the horrifying truth about the M4A1's origins and that the government army (KCCO) and the secret organization Paradeus want to use the M4A1 as a key to ancient technology, which will destroy her identity.
   M16A1 understands that Griffin and Kruger PMCs are too weak to protect M4A1 from the regular army and conspiracies. The only way to save her sister is to use the resources of Sangvis Ferri, seize the initiative, and control M4A1's fate herself, even if it means becoming her ultimate villain.
4. Clash of the Sisters
   Her story culminates in a massive battle, where a changed and fierce M4A1 duels her former mentor. This battle reveals how both dolls have grown and broken under the weight of war. M16A1 loses, but her actions trigger a chain of events that allows M4A1 to temporarily escape the attacks of global players.

The fate of M16A1 is one of the most tragic and twisted storylines in Girls' Frontline. From the trusted "big sister" of the AR squad, she turns into an enemy, but for a greater cause.
Here's a timeline of what happened to her.

1. Parasol virus infection
   During a critical operation, the AR squad finds itself trapped. To hack the Sangvis Ferri database and give its "little sister," the M4A1, a chance to escape, the M16A1 deliberately allows the enemy's "Umbrella" virus to infect its electronic network.
   This virus gradually takes control of the doll's AI, erasing its old personality and subordinating it to the orders of Sangvis Ferri. Realizing there's no turning back, M16A1 bids farewell to the Commander and the squad and departs for enemy territory.
2. Rebirth in Sangvis Ferri
   The virus completely restructures her programming. She gains physical modifications, changes her clothing to the dark tones of Sangvis Ferri, and wields new weapons. She becomes a fully-fledged leader of enemy forces on the battlefield.
   This comes as a terrible blow to the AR squad and the Commander: they are forced to fight against the one who taught and protected them. However, unlike other Sangvis Ferri bosses, M16A1 retains some of his memories and does everything he can to prevent the members of his former squad from being killed, often operating from the shadows.

The detachment's main secret
The tragedy of AR Team is that they were created not to save the world, but for one specific purpose: to protect the M4A1. Persica programmed the other dolls so that, on a subconscious level, they would be willing to give their lives for their leader without a second thought. Because of this, the team members have long been tormented by the question: is their love and devotion to the M4A1 genuine or merely hard-coded?

RO635 (Temporary Leader): Wields the RO635 submachine gun. She is not an original member of AR Team, but rather a member of the next generation of 16LAB dolls. RO635 temporarily leads the squad when the M4A1 is disabled and the M16A1 goes missing. She possesses a keen sense of justice, a strict personality, and the ability to hack enemy electronic systems on the battlefield.

M4A1 (Squad Leader): Wielding the M4A1 rifle, she is the mental core of the entire group. At the beginning of the story, she appears indecisive, timid, and vulnerable, often doubting her leadership qualities. However, her AI is imbued with unique technology related to the study of ancient alien artifacts, making her a prime target for all factions in the game. Over time, after suffering heavy losses, her personality hardens, transforming M4A1 into a cold and deadly fighter.
AR-15 (ST AR-15): Carries an AR-15 rifle. A proud, independent, and blunt puppet. She is deeply loyal to the squad, but suffers from an inferiority complex, as her civilian weapon is inferior to her sisters' military-grade weapons. Early in the story, she becomes infected with the dangerous Parasol virus, forcing her to sacrifice herself to save the team, but later returns in a modified form.
M16A1 ("Big Sister"): Wields an M16A1 rifle. The most experienced, cynical, and battle-hardened member of the squad. She enjoys alcohol, jokes constantly, but hides a dark past (she participated in the "First Butterfly Incident" before AR Team was formed). She acts as M4A1's protector. Later, to save the squad, she takes the Parasol virus and defects to the enemy faction, Sangvis Ferri, becoming a key antagonist.
SOPMOD II (M4 SOPMOD II): Wields an M4 SOPMOD II rifle. The most eccentric and terrifying doll in the squad. Outside of combat, she acts like a hyperactive, friendly child. However, in battle, she turns into a bloodthirsty sadist who enjoys dismembering enemy androids and collecting their parts as "trophies" for her own body modifications. She is madly attached to her sisters.

The Anti-Rain Team (AR Team) is an elite tactical unit of the Griffin & Kruger PMC, created by the eminent scientist Persica from the research organization 16LAB.
Unlike regular T-Dolls, which are converted civilian androids, AR Team members were designed from the ground up as purely military prototypes. Their key distinguishing features are a unique ASST network module, allowing them to function as a single organism, and an incredibly advanced AI capable of deeply human emotions.
Everyone knows this squad. No other squads better than this one have ever been recorded.
