The Rifleman is the backbone of the US Army Infantry. Riflemen are disciplined, courageous, have extremely high morale, and they absolutely do-not-quit. The most versatile element of a Fire Team, the rifleman is equipped with either an M16A4 or M4 MWS and variety of hand grenades. The duties of a Rifleman include, executing the orders of his Fire Team and Squad Leaders, maneuvering and providing cover fire with his element, and completing his mission at whatever cost.
