- "Close to mid-range 9mm submachine gun with low recoil and a medium fire rate. Favored by BOPE."
— In-game description
The slowest firing weapon in the game, the M12 is a fairly weak submachine gun for close-range engagements and nearly unusable for long-range. Its slow rate of fire does, however, make the gun's recoil easy to control. It's suited for a more methodical playstyle thanks to having the tightest hipfire accuracy out of all submachine guns.
- The M12 in reality fires in an open bolt configuration, meaning that one in the chamber would be impossible, unlike the in-game counterpart, which holds one in the chamber. This error is shared with other guns with an open-bolt configuration.
- Despite the reload animations correctly depicting the weapon with an open bolt by showing the operator locking the bolt to the rear, during firing, the reciprocating bolt is shown not locking back with the bolt, and instead reciprocates in a closed bolt fashion during firing.
