This converted Panzerkampfwagen 38(t), formerly a Skoda tank, was outfitted with a Russian 7,62 cm anti-tank gun, the PaK 36(r). This gun was rechambered for the more powerful PaK 40 shell. This self-propelled tank destroyer was one of the stop gap solutions before better German anti-tank vehicles were available.
Different types of Marder III existed, one with a Russian 76,2 cm anti-tank gun and two versions with a German Pak 70 anti-tank gun, but all based on the Panzer 38(t).
