By 1941 it became clear that Pz.Kpfw.IV's gun was inefficient against well-armored tanks. A modification of the tank with more powerful gun was being developed, and the requirements for the tank's gun were changed several times. The final version was a 75mm gun based on the Pak 40 anti-tank gun. The new modification of the tank was named Pz.Kpfw.IV Ausf.F2. Its mass production began in March of 1942. Pieces are suitable for use with the Zvezda Art of Tactic expandable board game.
