As of today, the use of War Wagons within the battlefields of the Empire is now obsolete, however it has been known that War Wagons are refitted to serve as either an Arcane Battle Altar or a War Altar of Sigmar. In the past, War Wagons can vary greatly in their size, with some War Wagons being only as large as an over-sized hay-cart, while others can grow to the size of an Empire fortress. As of now, War Wagons have been replaced with the newer and more heavily armored Steam Tank.
