B-10 recoilless rifle
The B-10 recoilless rifle (Bezotkatnojie orudie-10, known as the RG82 in East Germany) is a Soviet 82 mm smoothbore recoilless gun. It could be carried on the rear of a BTR-50 armoured personnel carrier. It was a development of the earlier SPG-82, and entered Soviet service during 1954. It was phased out of service in the Soviet Army in the 1960s and replaced by the SPG-9, remaining in service with parachute units at least until the 1980s. Although now obsolete it was used by many countries during the Cold War.

Description 

The weapon consists of a large barrel, with a PBO-2 sight mounted to the left. It is mounted on a small carriage, which has two large wheels, which can be removed. The carriage has an integrated tripod, from which the weapon is normally fired. A small wheel is fitted to the front of the barrel to prevent it touching the ground while being towed. It is normally towed by vehicle, although it can be towed by its four-man crew for short distances using the tow handle fitted to either side of the muzzle.

The tripod can be deployed in two positions providing either a good field of fire or a low silhouette. Rounds are inserted into the weapon through the breech, and percussion fired using a pistol grip to the right of the barrel. The PBO-2 optical sight has a 5.5x zoom direct fire sight, and a 2.5x zoom sight for indirect fire.
