Armed Assault Wiki
« The Vermin SMG utilizes a downward pointed recoil force together with an inline design, moving barrel to line with the shooters shoulder and hand to reduce the amount of recoil as well as muzzle climb. This greatly enhances the weapon's accuracy.

The Vermin .45 submachine gun.

The Vermin is a .45 submachine gun used exclusively by NATO forces in ArmA 3.


The Vermin is a personal defence weapon that uses a delayed blowback, closed bolt operation, and is chambered to fire the .45 ACP round.

It loads from 30-round box magazines and can achieve an impressive fire rate of up to 1,200 rounds per minute, with a muzzle velocity of 280 m/s. The Vermin can be fitted with optical sights on its top rail and can also mount attachments onto its muzzle. Although it does not have a side rail to attach laser pointers, it can fit a custom-designed flashlight in the notch located just above the end of the barrel.

Vermin fitted with an ACO and flashlight module.

With the exception of the ADR-97, the Vermin is generally superior to all other submachine guns in close quarters due to its (relatively) greater damage output and to high rate of fire. However, this advantage somewhat falls off at distances of 200 metres and beyond; particularly against armoured targets and solid objects such as wooden walls.

Nonetheless, it retains the highest fire rate out of all SMGs and being relatively compact, makes for an excellent weapon for both vehicle crews and when fighting in close quarters.

The Vermin only accepts a single magazine type. It has a "mass" value of 10 units:

.45 ACP 30Rnd Vermin Mag

Contains 30 rounds worth of .45 ACP ammunition. The last four rounds fired always consist of red tracers.


  • The Vermin is based on its real-world counterpart - the "KRISS Vector" SMG designed by KRISS USA, Inc.
  • Prior to Game Update 1.76, it was one of the few in-game weapons which could utilise an integrated flashlight. The Vermin was later refactored so that it could accept its flashlight (designed specifically for mounting on it) as an attachment instead.
