Vector is an obtainable Tactical Doll in the game.
A series of weapons developed by KRISS USA (Formally TDI), The SMG Vector (Gen I) was previously known as Super V in 2007, now with latest Gen II Vector released in 2015, "Super V" now merely refers to the articulated mechanism that reduces recoil on the gun.
A delayed blowback, closed bolt operated sub machinegun with a strange visual appearance, featuring selective fire mechanism with 2-round burst, semi and full auto. Prototype was designed to chamber the .45 ACP cartridge but Gen II Vector have variants that fires the 9x19mm Parabellum, can be fired at a rate of 1200 rounds per minute while feeding on a Glock 21's magazine, or a larger proprietary MagEx 25+ extended 25-round magazine. Also featuring foldable stock and accessory rail on top of the gun for mounting optics.
Vector is noted for it's recoil reducing designs, Super V Recoil Mitigation System, that is an articulated mechanism which allows the bolt and an inertia block to move downward into a recess behind the magazine well. Together with the rate of fire brought down to 1200 from 1500 RPM, this SMG can be easily controlled even during fully automatic firing of large calibre pistol cartridges.
Gen I Vector variant are no longer in production, all further production of Vector units from KRISS USA are now Gen II. Gen II Vector SMG is available only to the military and law enforcement agency while other semi automatic variants are available for civilian market.
SA shared comments on the design inspirations of Vector on the Official Girls Frontline Art Book.
"Upon seeing the weapon Vector for the first time, I felt like that she should be a girl with silver hair. Personality should be the serious type, and she should also appear to be a bit cold. (第一次看到vector的外形时，就觉得应该是个银灰色头发的、认真又有点冷的少女)".
"Since it is a modern weapon, so her costume doesn't look as suitable for combat as the other T-doll's costumes(因为本身是现代枪，所以服装上看起来不是像其他人那样有战斗感的战术服装)."
"The colour theme of her outfit were taken from the gun, short skirt to match the short hair. Main colouring theme is black and creamy yellow, together with a clean white shirt, hoping that it gives people a sense of fresh and cool just from looking at her.(从枪身上提取图形和颜色为元素，选择了不累赘的连衣短裙和短发，主色是黑色和黄色搭配干净的白衬衣，希望能给人清爽帅气的印象)"
Vector is also one of the taller SMG T-dolls, body height well exceeds 160cm, though her height seem to be bashed down a lot with her Kitty Paw costume...
Official character description would have her down as a T-doll with very few words and reliable performance, despite her weird personality she is actually fairly popular amongst T-dolls. Vector possesses an incredibly pessimist characteristic, she radiate intense level of negative energy with the way she acts with the things she says, she would expect the worst outcome out of any situation.
The way Vector act out is likely a referred to the difficult and intertwined history of the actual weapon. Being developed by an American company, designer is Swedish while the mechanism copyright is French. After first public reveal, the weapon received doubts from the audience due to the strange visual appearance. Over a period of several years redevelopment, even a name change for both the weapon and the company, the weapon's performance is finally being admired by public. Despite that it still did not enter Military service and the civilian market complains about it's pricing (Popular with the film industry though due to it's Sci-Fi look).
Together with the high default rate of fire/damage and the given ability, Vector is in fact, the strongest thrown-grenade type unit in the game. Her default shooting damage when buffed is notable, while her Molotov skill is very effective against large enemy crowds and/or high evasion enemies during day and night missions. On top of that Vector is able to provide a massive rate of fire bonus to the AR unit standing behind her. Note that Vector's default evasion is lower than most SMG, so her tanking performance is not as ideal as the others.
As a 5* SMG Vector is actually fairly common, most people will have received their Vector within a month of playing, which could mean for most players, her expansion is less expensive than the other 5* T-dolls.
Vector's only story involvement was as part of Hitori Bocchi, she was one of the two main characters who represented Girls Frontline during the collaboration event with Honkai Gakuen on November 16th 2017.
Vector was the first T-doll to make contact with a Honkai character after she encountered HG Kiana. (Note that Hitori Bocchi is told from a perspective of Kiana being the Commander, the actual player character "could not interact with this event due to unnameable reasons", according to HG Five-seveN)

|Introduction||KRISS Vector冲锋枪，原本的名字是Super V。初次公布样本后，承蒙大家笑话了一年，直到后来才公布了真正的原型。样子虽然难入你们的法眼，不过都是为了让你们舒服才做成这样的，（冷笑）多少带点感激之情去使用吧。||KRISS Vector SMG, original name was Super V.
