sIG 33 auf Geschützwagen I, II, 38t

The sIG 33 auf Geschützwagen was a World War II self-propelled gun in service with the the German Army between 1940 and 1945. It consisted of a 150mm-caliber infantry gun emplaced on the chassis of the PzKpfw I, II, and 38t tanks. It first saw combat action in May 1940, in the Battle of France. The three-man crew operating the gun on top was protected by a high-profile roofless turret, which made it look rather awkward and cumbersome. However, it was a successful attempt to provide the artillery with speed, rendering it able to take part in the German Blitzkrieg. The sIG 33 auf PzKpfw 38t was massively produced and fielded from 1943, having the official designation SdKfz 138/1 (Sonder  Kraftfahrzeug 138/1). The gun had an effective range of 5 km (3.5 miles) and a rate of fire of 4 rpm. It was used to tear out gaps in the enemy lines for the German spearhead infantry units push in through.
