Gunner's Fact or Fiction: Semi vs. Automatic
U.S. Marines, CWO5 Christian Wade, 2nd Marine Division Gunner, and Cpl Gerald Tredo, 3/6 infantryman, compare shot groups while firing on semi-automatic and full automatic at various distances on October 18, 2017 at Camp Lejeune. The intent is to provide guidelines on when it is most appropriate to use semi automatic and full automatic when suppressing an enemy. (U.S. Marine Corps video by Cpl. Bethanie Ryan)
