But while it may have looked the part, the M103 proved to be the last breath of a dying breed – that breed being the heavy tank itself.

The M103 Heavy Tank (officially designated 120mm Gun Combat Tank M103)[3] served the United States Army and the United States Marine Corps during the Cold War. The last M103s were withdrawn from service in 1974.

M103 was, however, a pretty bad tank due to sharing an overloaded drive system with the M48. Combined with its short range, this meant M103's would be predictably lost in a retreat. NATO planned to retreat in any opening round in Europe, so M103's were worse than useless on the only front in which peer-peer armored warfare was foreseeable.

The M103 underwent several modernization phases, including the “A2” project, but eventually, in the early 1970s, even the Marine Corps transitioned away from these obsolete heavy tanks. Thus, the T43/M103 heavy tank had a relatively short service life, lasting less than five years in the Army and three times longer in storage.
