7.5 cm 75mm PaK 40 auf Raupenschlepper Ost (RSO) German WW2

The Australian Armour and Artillery Museum in Cairns QLD Australia. The 7.5 cm PaK 40 auf RSO stemmed from a concept rooted in German Panzerjäger vehicles, leveraging the Raupenschlepper Ost (RSO) chassis. Designed as an Eastern Tracked Tractor, the RSO was initially a cargo vehicle tailored to navigate tough Eastern Front conditions. In 1943, plans were initiated to mount a 7.5 cm PaK 40 anti-tank gun on the RSO chassis, aiming to render stationary anti-tank weapons mobile.The sides of the Raupenschlepper Ost (caterpillar tractor east) SPG folded down to produce a larger platform for the crew of the 7.5cm Pak 40 gun.
