M46, M47, M48 an M60 Patton were the United States Army's principal main battle tanks of the Cold War, with models in service from the late 1940s to the 1990s. The M46 was the primary U.S. tank in the Korean War and the M48 was the primary U.S. Army and Marine Corps tank during the Vietnam War. The M47 saw no action while serving with the U.S. military and the M60A1 saw limited service in Desert Storm. It was widely used by U.S. Cold-War allies, especially other NATO countries. The many models were named after General George S. Patton, commander of the U.S. Third Army during World War II and one of the earliest American advocates for the use of tanks in battle.
