The thing with tanks and mobilized ground vehicles, is that they were in all theater's. Why assume that the only way to include tanks to game play is to have a tank battle. Being able to drive or man a gun in the ground vehicle, is the important part here. There are countless possibilities! Whether a gunner, or a staff car driver in a truck convoy, gunner on a supply train, rogue tank taking out whatever is put in his sights...just think "Halo"
, flying above or on the ground in a tank, its all good!
