In World War II, the 107mm mortar saw service with Soviet mountain infantry as a divisional artillery weapon.[3] Weapons captured by the Germans were given the designation 10.7 cm Gebirgsgranatwerfer 328(r).[4] 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.[5]
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.[6] 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.[7]
