Pz.Kpfw.IV L/70(A) Germany produced a number of tank destroyers in an effort to resist the tide of armor pushing against it on all sides. One of these designs was the Panzer IV/70(A). As indicated by its name, this vehicle was based on an unchanged Panzer IV chassis (specifically an Ausf.J) and it was produced by Alkett as an interim design. A total of 278 tank-killers were produced concurrently with the more common Jagdpanzer IV/70(V) from August 1944 to March 1945. A long-barreled 7.5cm PaK 42 gun was mounted in the superstructure. The nose-heavy attitude of the vehicle dictated that the first four road wheels be steel-rimmed. The vertical lower sides of this superstructure quickly distinguish this type from the Jagdpanzer IV/70(V).
