The Panzer IV/70(A) (Sd.Kfz. Index: Sd.Kfz. 162/1) is the second variant of the Panzer IV medium tank-based tank destroyer family. Hitler ordered Alkett (A), the StuG III's manufacturer, to redesign the Jagdpanzer IV superstructure to accommodate the new main armament in July 1944 so that 75 mm Panzerjägerkanone 42 L/70 tank gun could be sent to the front as soon as possible. Due to the new armament being larger than the previous one, additional vertical steel plates had to be welded onto the chassis to compensate for height differences when mounting the redesigned superstructure onto the original Panzer IV medium tank chassis. From August 1944 to March 1945, only 278 were constructed.

Introduced in Update 1.41, the Panzer IV/70(A) should only be used for defensive roles. Its primary armament is among the best for this class. With its high penetration and muzzle velocity, it can easily defeat all but the most resilient tanks. However, frontal protection is highly variable when under fire. If at all possible, steer clear of conflict and let the other players take the hits so that the player can decide when and how to engage. Always maintain a safe distance from the adversary and stay out of the main areas of combat.

It was first introduced as a premium pack but removed from the store after the 2018 Winter sale. It was reintroduced in 2018 for War Thunder's 6th Anniversary as a premium purchasable for Golden Eagles and again removed after the 9th Anniversary Sale.
