The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States.
The M1905 bayonet has a 16-inch (40.6 cm) steel blade and a 4-inch (10.16 cm) handle with wooden or plastic grips. The bayonet also fits the U.S. M1 Garand rifle. From 1943 to 1945, a shorter, 10-inch (25.4 cm), bladed version was produced with black or dark red molded plastic grips, and designated the M1 bayonet. A number of M1905 bayonets were recalled from service, their blades cut down, and reissued as M1 bayonets.
