The Krupp Protze (Kfz.70 - Standard configuration for personnel carrying) was a six-wheeled 6×4 German truck and artillery tractor produced between 1934 and 1941 and heavily used in World War II. It was powered by a 4-cylinder, 55 hp or, from 1936, 60 hp Krupp M 304 petrol engine. Its main purpose was to tow artillery, especially the 3.7 cm Pak 36 anti-tank gun (designated Kfz 69), and transport motorized infantry (designated Kfz 70).

As the German army faced ever increasing numbers of Allied armour, more ways were found to place anti-tank weaponry on already existing chassis, in order to try and counter the Allied numerical superiority. The Raupenschlepper Ost (RSO) was no exception to the armed conversions that were built upon so many German vehicles at the time. The decision was made in 1943 to take the well proven battle tractor and place a Pak 40/4 on its back, in order to provide more mobile anti-tank capabilities on the front line.

The Sd.Kfz. 124 Wespe (German for "wasp"), also known as Leichte Feldhaubitze 18/2 auf Fahrgestell Panzerkampfwagen II (Sf.) ("Light field howitzer 18 on Panzer II chassis (self-propelled)"), is a German self-propelled gun developed and used during the Second World War. It was based on a modified Panzer II chassis.

The Sturm-Infanteriegeschütz 33B ("Assault Infantry Gun 33B"), was a German self-propelled heavy assault gun used during World War II.
