Heckler & Koch MP5A2
During the weapon selection the MP5A3 shows up with a fixed stock, suggesting that it is the MP5A2.
FN P90
The FN P90 is the other available submachine gun in the game. The 50-round magazine can be a big advantage over the other weapons in the game, considering that 4-5 bullets are needed to kill an enemy soldier.

Heckler & Koch G36V
The G36V is a very accurate weapon with a slow rate of fire.
