The Jagdpanzer IV, Sd.Kfz. 162, was a tank destroyer based on the Panzer IV chassis built in three main variants. As one of the casemate-style turretless Jagdpanzer (tank destroyer, literally "hunting tank") designs, it was developed against the wishes of Heinz Guderian, the inspector general of the Panzertruppen, as a replacement for the Sturmgeschütz III (StuG III).
