The first true tanks were of British origination and presented as the "Landships" of World War 1. Primarily used as infantry support systems, the tank proved critical in several major late-war victories for the Allies. During the decades following, tighter defense budgets limited advanced development and it was not until the German Blitzkrieg of World War 2 that tanks saw a "renaissance". During the war, the light, medium and heavy tank classes ruled the battlefields with each design intended to outdo the previous. At the close of the war, the "Main Battle Tank" was born with the introduction of the British "Centurion" in 1945. This effectively produced a single class with qualities of the three previous. Today, the Main Battle Tank enjoys a dominance of the battlefield that has only served in developing evermore potent anti-tank measures in turn.
There are a total of 65 Main Battle Tanks in the Military Factory. Entries are listed below by initial year of service. Flag images indicative of country of origin.
