The Granatnik wz.36 was a Polish grenade launcher designed in originally in 1927 as "wz. 30" and later modified in 1936. It entered service in 1936 becoming the standard grenade launcher of the Polish Army; it was still in use during the German Invasion of Poland in 1939. The wz.30 had a maximum range of 700 meters; this was increased to 800 meters in the wz.36. They both fired the same 46 mm shell, weighing 0.76 kg. About 3,850 of these 46 mm mortars were produced by 1939. Typically 81 such mortars were distributed to each Polish infantry division—three per company.
