At the start of Soviet involvement in World War II, they were largely a "tankless" Nation. It took little time for Germany to abandoned it's Non-Aggression Pact and invade them. With American and British material support, The Soviet Union set about to create a "robust" Tank Corps. One of the first series of Soviet Armor fielded was The JS-III Heavy Tank. Seen as a counter to Germany's Panzer Tank, The JS-III, nicknamed "The Stalin", was a 4-man - 57 ton Main Battle Tank. Capable of a top speed of 20 mph, it featured 4.7 inches of armor plate. It's Main Gun was a 120mm, capable of firing High Explosive shells. Secondary armament included either a 7.92mm or 12.7mm Machine Gun. Described as a "Giant Beetle", The JS-III was effective in countering German Armor, both The Panzer and Tiger Tank Series. With 3 variations somewhat rapidly conceived in 1944, it was the forerunner of the mighty T-34 Battle Tank (implemented the same year).
