This tank destroyer is Panzer IV with a long PaK 42 Anti-tank gun. Panzer IV/70 (A) Sd.Kfz. 162, the (A) referes to the creator of the tank Alkett. The PaK 42 is the same gun used in the Panzerkampfwagen IV Panther tanks. This 75 mm gun could outrange most Allied tank weapons and therefore it was considered a real threat on the battlefield. Original the Jagdpanzers PaK 42 had a muzzle break. Most crews removed this for the low silhouette of the tank an d the low placement of the gun caused clouds of dust after firing and gave away the position of the tank destroyer.
This particular tank was captured by Allied forces and used by the Free French until the end of the war. The Jagdpanzer was left as it is, with impact damage and even an unexploded shell in its frontal armor.
