82-BM-37

The M-37 or 82-BM-37 (батальонный миномёт, battalion mortar) is a Soviet 82 millimeter calibre mortar designed by B.I. Szayrin and accepted into service in 1937. The design of the M-37 is based on the earlier French Brandt mle 27/31 mortar with Russian modifications.[5] The main difference between the 82-PM-37 and the earlier 82-PM-36 was the adoption of a round base-plate, revised traverse/elevation controls, simplified sights and spring-loaded shock absorbers on the bi-pod to reduce the amount of relaying needed between shots. It was designed to be able to fire western 81mm captured ammunition whilst not permitting the enemy the same advantage[6] The German designation for captured M-37 mortars was 8.2 cm GrW 274/2(r).[7]
