Principles of Operation (1943) United States Rifle, Caliber .30, M1
The above U.S. Army training film explains the principles of operation of the M1 (Garand) Infantry Rifle.
John Garand’s M1 rifle was developed at Springfield Armory over a five-year period and put into production in August 1937, with over 5 million produced by SA, Winchester, Rock Island Arsenal, International Harvester and Harrington & Richardson by 1957 when it was theoretically replaced by the M14.
Gen. George S. Patton called it “the greatest battle implement ever devised” after seeing it in action during some of the heaviest ground combat in World War II. It went on to hold the line in Korea, the Cold War, and the early days of Vietnam. The old M1 remained in National Guard armories through the 1970s and as many as 250,000 DoD-owned Garands still serve with various military and civilian honor guards.
