They were introduced into the German military in 1933, hence the designation. About 4,600 were made during the design's production life. The 15cm sIG 33 close infantry support guns were made in many variants, some of which were mounted on vehicles such as the chassis of a Panzer II, 38(t), Panzer III, and Panzer IV tanks, making them self-propelled guns.
