First produced in 1936, the Panzer IV has the distinction of being the most widely produced Axis tank during the war.
Despite its obsolete design, the Panzer IV remains in use with the UN fielding the late war Ausf. G and Ausf. J versions. It has also developed the Ausf. K model.
The Ausf. G is the base version of the Panzer IV. It was used on all fronts in the European theatre by the Axis powers.
Considered by many to be a retrograde, the Ausf. J is the result of heavy tank losses and the need to replace them at the front. Optimised for mass production, it is a stripped down version of the basic model.
The Ausf. K is a UN designed variant of the Panzer IV. This post war update makes use of better availability of rare metals that were not available towards the end of the war. The UN have also further developed the Ausf. K with a better engine and AA capabilities.
