Developed in 1942, the 12 cm (about 4.7 in) GrW 42 was an attempt to give German infantry units a close support weapon with greater performance than the mortars used in general service at the time. This weapon was very similar to the mortar used by Soviet forces on the Eastern Front which in turn was an improved version of the French 120 mm Brandt Mle 1935 mortar. The 120 mm Brandt m35 was used in limited quantities during the Battle of France and exported to the USSR and other nations before the country's capitulation in 1940.
