107mm M1938 mortar

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.

In World War II, the 107mm mortar saw service with Soviet mountain infantry as a divisional artillery weapon. 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.

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. 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.
