Today’s invention is a device intended to allow a tank to escape the battlefield when its running gear has been damaged.
A motorised set of spare wheels (or tracks) is attached to a frame stored eg at the rear of the vehicle.
When a track has been destroyed, the turret rotates, engages with this frame (perhaps using the main gun barrel, if appropriate), rotates to the damaged side and provides enough traction to shed the damaged components and retreat rapidly.
