The "Krupp-Protze" was a six-wheeled German truck and artillery tractor used by German forces in World War II. It was powered by a 55 hp or 60 hp (after 1936) Krupp M 304 4-cylinder petrol engine. Its main purpose was to tow artillery, especially the PaK 36. The Pak 36 (Panzerabwehrkanone 36) was a German anti-tank gun that fired a 3.7 cm calibre shell. It was the main anti-tank weapon of Wehrmacht infantry units until 1942.
This vehicle was extensively used on the Eastern Front, North African campaign and in France and Sicily. The "Krupp-Protze" was of relatively advanced design. It was mass-manufactured between 1933 and 1941. Its fuel consumption was relatively high (24 Litres / 100 km on road) in comparison to the comparable Opel Blitz 1.5 t truck (16.5 liters / 100 km, produced 1938 - 1942). Total production was about 7,000 units.
