The Katzchen is a great way to represent advanced mechanized infantry on your global war game board. Once Germany develops Advanced Mech using the Global War-2nd Edition tech chart you are in a good position to take out the Soviets. The Advanced Mech is a 4/5 with a move of 2 and like normal mech pairs 1:1 with blitzing armor.
The Katzchen itself only entered prototype stage as an armored personnel carrier and never saw combat.
