152mm BR-2 Gun Mod.1935 – Walk Around

The 152 mm gun M1935 (Br-2) (Russian: 152-мм пушка обр. 1935 г. (Бр-2)) was a Soviet 152.4 mm heavy gun, produced in limited numbers by the Barrikady Plant in Stalingrad in the late 1930s. The most unusual feature of the gun was its tracked carriage, shared by a number of Soviet heavy artillery systems of the interwar period. Despite a number of drawbacks, most notably limited mobility and short service life of the barrel, the weapon was employed throughout the German-Soviet War; an upgraded variant with wheeled carriage, Br-2M, remained in service at least until the 1970s.
