IV号戦車
In keeping with the wartime German design expediencies of mounting an existing anti-tank gun on a convenient chassis to give mobility, several tank destroyers and infantry support guns were built around the Panzer IV hull. Both the Jagdpanzer IV, initially armed with the L/48 tank gun, and the Krupp-manufactured Sturmgeschütz IV, which was the casemate of the Sturmgeschütz III mounted on the body of the Panzer IV, proved highly effective in defense. Cheaper and faster to construct than tanks, but with the disadvantage of a very limited gun traverse, around 1,980 Jagdpanzer IVs and 1,140 Sturmgeschütz IVs were produced. Another tank destroyer, the Panzer IV/70, used the same basic 75-millimeter L/70 gun that was mounted on the Panther.
