The M60 machine gun began development in the late 1940s. The U.S. Army officially adopted the M60 in 1957.The M60 later served in the Vietnam War as a squad automatic weapon with many U.S. units. Every soldier in the rifle squad would carry an additional 200 linked rounds of ammunition for the M60, a spare barrel, or both. The up-gunned M113 armored personnel carrier ACAV added two M60 gunners beside the main .50 caliber machine gun, and the Patrol Boat, River had one in addition to two .50 cal mounts and received the nickname "The Pig" due to its bulky size. Vietnam's tropical climate harshly affected weapons, and the M60 was no exception. Its light weight made the gun damage easily and critical parts like the bolt and op rod wore out quickly. Even so, soldiers appreciated the gun's handling, mechanical simplicity, and effective operation from a variety of firing positions. Navy SEALs used M60s with shorter barrels and no front sights to reduce weight further. Some SEALs had feed chutes from backpacks to have a belt of thousands of rounds ready to fire without needing to reload. In the 1980s, the M60 was partially replaced by the M249 within Army infantry squads.
In the 1980s, Saco Defence (now part of General Dynamic) developed the M60E3, an improved version of the M60E2. US Marine Corps and adopted in 1986 to replace their stocks of original production M60s.
