America’s last heavy tank, the improved large-turreted tracked platform for the long-range 120mm cannon. USMC type M103A1 tanks were up-engined with matching uprated transmission and classified M103A2; parts are included in the kit for the characteristic raised rear engine deck. 208 type M103A2s were converted for USMC service until retirement in the early 1970s. An example is preserved in working order at the Tank Museum in Bovington, Dorset, and is the only surviving M103 outside the United States.
