82mm 150 M-37

The 82-BM-37 is an 82mm smoothbore, muzzle-loading mortar developed by the Soviet Union. It was a standard battalion-level support weapon during World War II, known for its simplicity and effectiveness and was widely exported and copied.

Designed by the Dorovlev bureau to improve upon the earlier M-36 model, this mortar officially entered Soviet service in 1937 to provide infantry battalions with a highly portable, rapid-fire indirect support weapon. Its 82mm caliber was deliberately chosen so it could utilize captured German 81mm mortar rounds, while preventing German forces from using Soviet ammunition in their own smaller-caliber weapons. Following its extensive deployment in the Winter War and World War II, the weapon saw widespread combat during the Korean and Vietnam Wars, where its lightweight design made it ideal for guerrilla tactics. Although superseded in modern Russian service by the 2B14 Podnos, the M-37 remains in active service with numerous militaries and irregular forces globally today.
