It uses 5.56x45mm ammo. it's also capable to launch a white phosphorous grenade at the cost of 10 bullets. In comparison with the SMGs, this gun is much more accurate, with far less idle sway and more powerful per shot, but at the expense of a slightly slower rate of fire as well as being louder than the other automatic weapons. It makes its debut during the first of the New York missions that take place after the first visit to Iraq.
