This Jagdpanzer 38(t) “Hetzer” was on display at The Bastogne War Museum.
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.
Today they are popularly known as Hetzers, but this name was far less common at the time.
