#13 — Panzer IV: Germany's Only Tank That Lasted the Whole War
The Panzer IV is the only German tank that served from the first day of World War II to the last — from Poland in September 1939 to Berlin in May 1945. Over 8,500 were built, making it Germany's most-produced tank (excluding the StuG III assault gun), and it served on every front where the Wehrmacht fought.
Originally designed as an infantry support tank with a short-barreled 75mm gun, the Panzer IV was continuously upgraded to meet escalating threats. The Ausf F2 variant received the long-barreled 75mm KwK 40 L/43 in 1942, transforming it into a genuine tank-killer capable of penetrating a T-34 at 1,500 meters. By the Ausf J, it had 80mm of frontal armor plus Schurzen side skirts against shaped charges. The Panzer IV was reliable, maintainable, and adaptable — everything the Tiger was not. German crews trusted it because it started every morning, ran all day, and could be repaired in the field. In a war that consumed military equipment at an industrial pace, the Panzer IV's greatest virtue was simply that it kept showing up.
