The M4 carbine is an air-cooled, direct impingement gas-operated, magazine-fed carbine that’s a shorter and lighter variant of the M16A2 rifle. It’s already heavily used by the U.S. Armed Forces and is replacing the M16 rifle in most U.S. Army and U.S. Marine Corps combat units as the primary infantry weapon. Among its capabilities, it has a distinctive step in its barrel for mounting the M203 grenade launcher with the standard hardware, and can fire in semi-automatic and three-round burst modes or in semi-auto and full automatic modes, depending on the model.
In this video, U.S. Marines with Special Purpose Marine Air-Ground Task Force – Southern Command (SPMAGTF-SC) conduct marksmanship training at Marine Corps Base Camp Lejeune, NC. The shooting range is part of pre-deployment training for an upcoming deployment to Central America and will prepare the Marines to train alongside partner nations. One must remark that it’s always great to watch Marines getting ready for deployment.
