The M-37 or 82-BM-37 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.
The M-37M is an improved version with lighter base plate and a device to prevent double loading.
82-BM-37 Mortar in The War That Came EarlyEdit
Although, the Red Army had plenty of artillery cannon, they also backed their infantry up with just as many 82mm mortars. Many German soldiers complained about the effectiveness of these weapons by nearly every Russian infantry platoon. While lacking the range of artillery, it none the less caused the Germans to keep their heads down.
