This paper model is a Hetzer, also called Jagdpanzer 38(t) (Sd.Kfz. 138/2), a German light tank destroyer of the Second World War based on a modified Czechoslovakian Panzer 38(t) chassis, the papercraft was created by worldoftanks.
The name Hetzer was at the time not commonly used for this vehicle. It was the designation for a related prototype, the E-10. The Škoda factory for a very short period confused the two names in its documentation and the very first unit equipped with the vehicle thus for a few weeks applied the incorrect name until matters were cleared. However, there exists a memorandum from Heinz Guderian to Hitler claiming that an unofficial name, Hetzer, had spontaneously been coined by the troops. Post-war historians basing themselves on this statement made the name popular in their works, the vehicle was never named as such in official documents. For more information please click here.
