It had a very large are of effect and dealt a large amount of damage to all targets. Its was also indiscriminate and would harm all target regardless of faction allegiance. Infantry were immune to its effects and took no damage at any range from the blast.

The tank would begin by starting a large pump on its back that would continue to increase in speed with each repetition. The single crew member would bail out and remove himself from the area. The repetitions would get faster and faster until the tank finally exploded and released seismic waves.

After the war, the tanks were decomissioned and research concerning them destroyed.
