Medium Steam Tank Mk. XXI (commander)
The Medium Steam Tank was built to replace the Heavy Steam Tank (Mk. I). Field commanders called for a vehicle with the same amount of firepower in a more compact version, making for a smaller target. Although much smaller, it consumes an equivalent amount of coal and moves at roughly the same speed as the Heavy Steam Tank.
The Medium Steam Tank is armed with three automatic rifles and a pair of turret-mounted cannons. (wind-up motor allows it to move on its own, up to three feet)
