203 mm howitzer M1931 (B-4) was a 203 mm (8 inch) Soviet heavy howitzer. These guns were used with success against heavy German fortifications and in urban combat for crushing protected buildings and bunkers. This weapon was used right up until the end of the war in the Battle of Berlin where the Red Army would fire these guns at point blank range to smash German fortifications with their heavy 203mm shells.
