The M60 Patton was the fourth and last of the Patton series medium tanks of the U.S Army. The M60 served as the primary main battle tank of the Cold War, with models in service beginning in 1960 up through the 1990s. The newer model M60 was the U.S. Army's basic main battle tank stationed in Europe (Germany) and South Korea during the Cold War, while the older M48 Patton tanks were being deployed in Southeast Asia (Vietnam) from 1965 through 1975, by both the USMC and US Army. It was widely used by U.S. Cold War allies, especially other NATO countries. The tank belongs to the Patton family of tanks, 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. It was a further development of the M48 Patton tank.
