German experimental super-heavy tank Mouse.Mouse was created to fight enemy tanks like the IS 2, T-34 and Sherman, and also to replace bunkers. the tank has 2 guns, 128 and 75 mm. The mass of the tank was over 100 tons. The development of the tank was entrusted to Ferdinand Porsche in 1942-43. Production began in 1943-44 by the Krupp company. As a result, 2 tanks were built, which, when the red army approached, were blown up, but not completely. now the only mouse is now kept in the tank museum in Kubinka, Russia. Mouse to this day remains the only super heavy tank in the world adopted (1945-1945).
