M103A1 heavy tank. DRAGON 3548

The 65-ton M103 Heavy Tank that served with the US Army and US Marine Corps (USMC) during the height of the Cold War from 1957-1974. Its whole design was predicated on the need to counter Soviet heavy tanks, and thus it boasted a rifled 120mm M58 cannon for long-distance engagements. This gun fired a separate-loading round, which required two loaders, thus giving five men in the crew. The armor was up to 180mm thick on the front of the turret. Some 300 T43E1 tanks were built, of which 219 were later converted to M103A1 standard, and 153 rebuilt into M103A2 s.
