The Sub-Machine Guns are made to give a soldier more range and fire power than a pistol, while still enough mobility to maneuver arround a battle field than a full sized rifle.
The M-3685 is specifically made not only to provide the troops with those crucial parts, but to provide substantially more firepower than a standard submachine gun. Designed to be able to handle more powerful caliber rounds, this gun is an excellent choice for soldiers who wish to carry tremendous amounts of fire power while still able to move around easily.
