The 203mm B-4 was a heavy howitzer which was mounted on the same tracked chassis as the 152mm Br-2. Like the Br-2 it could be moved in one piece but only over short distances and had to have the barrel removed to allow for movement in two parts over long distances. It saw extensive service during world war two and was used to support offensive actions at Moscow, Stalingrad, the Crimea and finally Berlin.
