クビンカ戦車博物館
The only self-propelled mount of the Br-2 was a variant of the experimental SU-14, based on the chassis of the T-35 heavy tank with elements of T-28 medium tank, and intended to carry either 203 mm howitzer or 152 mm gun. The prototype armed with Br-2 is referred to as "SU-14Br-2". In Autumn 1941 the experimental piece shelled German forces from Kubinka proving ground. The vehicle is still on display in the Kubinka Tank Museum.
