The Soviet 107mm M1938 mortar was a scaled-down version of the 120mm M1938 mortar intended for use by mountain troops and light enough to be towed by animals on a trolley.[1]


In World War II, the 107mm mortar saw service with Soviet mountain infantry as a divisional artillery weapon.[2] Its last significant use in battle was in the Vietnam War. The ability to break down the weapon made it particularly suited to the rugged terrain of Vietnam.[3]

The mortar fired a lighter high explosive round (OF-841) and a heavier HE round (OF-841A). The lighter HE round actually carried a larger bursting charge than the heavier round.[4] Both rounds used GVMZ-series point detonation fuzes.

Recently, the weapon has been seen in use by rebel forces during the 2011 Libyan civil war.[5]
