The Jagdpanzer 38 (Sd.Kfz. 138/2), originally the leichter Panzerjäger 38(t), known mostly post-war as Hetzer, was a German light tank destroyer of the Second World War based on a modified Czechoslovakian Panzer 38(t) chassis.
German armored forces in World War II created a variety of vehicles by mounting anti-tank guns on the chassis of obsolete tanks. These machines performed even better than expected, yet were still vulnerable due to high vehicle profiles and open-topped turrets. Allied bombings took a heavy toll on German production facilities, and further increased the need for an easily produced yet effective light tank destroyer to replace vehicles like the StuG III and Marder series. Prototypes of the Jagdpanzer 38 were ready by 1944 and mass production began in April of that year. The Jagdpanzer 38 was covered entirely with sloped armor, and possessed a compact form and low silhouette, giving it much improved defensive ability over other self-propelled guns. Armament consisted of a 7.5 cm Pak 39 L/48 gun and a remote-controlled MG 34. It featured a wide body to accommodate the four-man crew, as well as strengthened lower hull with enlarged wheels, guide rollers and tracks.
