For a time, the Heavy Tank was the pinnacle in armor design for many of the leading military powers. It saw its peak usage during World War 2 though development of such types continued into the late-1950s. Those managing to reach operational-level status by then were ultimately retired during the 1990s for good. The Heavy Tank was replaced in frontline service by the arrival of the Main Battle Tank (MBT).
There are a total of (42) Heavy Military Combat Tanks in the Military Factory. Entries are listed below by initial year of service descending. Flag images indicative of country of origin.
