T-34
"Quantity has a quality of its own."
- – Joseph Stalin
The T-34 is the posterchild of the Soviet Union, the glorious tank of the proletariat, and the most versatile platform available to you as a Red Army commander. Cheap, simple, but capable, the T-34 became the most produced tank of the war at 80,000 units and was one of the only tanks to serve all the way through the war from the invasion of Poland in 1939 to the Berlin parade in 1945. In 1943 after the Battle of Kursk the T-34 was up gunned with and 85mm cannon to help it deal with heavier German armor and in this guise it pushed all the way from Leningrad to Germany.
In game, the T-34 is a solid medium tank with a few interesting features that make it difficult to play in most situations but also help drive the price down. When used right, you can drown your opponents in a tide of glorious stalinium. When used clumsily, however, you'll simply waste lives and bring shame to your country.
