The VIP Bunker was a type of bunker used during War of the Three Powers and later conflicts. They were used as command centers for high-ranking commanders on the battlefield. Thus, they were well armoured and were often heavily guarded. VIP Bunkers were important objectives for invading armies, as it offered a chance to eliminate an enemy leader or, if captured, command the allegiances of enemy forces. Some examples, on the War of the Three Powers, were the following battles: * Allied invasion on Tokyo. * Battle of Von Esling Airbase * Battle of Mt. Fuji.
