The Charlemagne Mk. I is a super-heavy armored fighting vehicle developed by the European National Defense Department in secret in the late 2140s for the future Old World Conglomerate. The tank first entered service in 2150 towards the end of the European Civil War, where it saw sporadic use as fortress buster in the province of Britannia.
It features advanced fire control and complex heat regulation systems, automatic target priority recognition software and possesses an auxiliary power socket at the back of the turret, alllowing it to utilize an external power source to dramatically increase its rate of fire for stationary defense purposes.
