It appeared a bit incongruous that the German military would be willing to sacrifice a seemingly functional fighting vehicle for a weapons test instead of logically using a captured enemy vehicle, as resources came at a premium by 1944, even in the alternate timeline, as stated by the German general in "Storm Front". However, the particular version shown, the Panzer IV Ausf. C, D or F1, was by 1944 obsolete, outgunned by the newer allied tanks – though it still would have been a valuable resource for its spare parts.
Intended to be an intermediate fighting vehicle, starting production in 1936, the Panzer IV proved to be highly adaptable for upgrading, and has remained in production right up until the end of World War II, the only German tank to do so. In the end, discounting the derivatives that were based on its chassis, 8.800 units were produced, more than any other type of German tanks. It has also become the only German tank that saw combat service after the war in the Syrian army during the 1967 Six-Day War, still holding its own.
