The 122mm D-25T is the main gun of the Soviet IS-2 Model 1944 heavy tank with a very impressive calibre, which is the biggest in-game. Although it hasn't the best penetration of all heavy tanks, that's sure made up in its damage output. Originally known as the A-19 corps howitzer in 1931, it was modified in 1943 to fit in the new Iosif Stalin tank. This conversion is known as the D-25 Tankovaya (Tank mount), and remained in Soviet service until the 50s.
