When a tank goes in circles, it typically means that the tank has sustained damage, often to one of its tracks or the steering system. If the engine continues to run but one track is destroyed or the steering is jammed, the tank will pivot around the damaged track and spin uncontrollably. This can happen after the crew has been killed or incapacitated, meaning no one is left to stop or control the tank. Such tanks are sometimes called "ghost tanks" because they keep moving in circles with no driver, driven only by momentum and engine power. This phenomenon has been reported in various conflicts, including the Syrian Civil War and World War II. It is an eerie sight and not intentional but a mechanical consequence of the damage sustained by the tank.
