Vehicles can drive onto the bunker pad and be surrounded by walls raised from the ground. Once inside, the vehicles are immobilized, but still have full use of their weapons. Their rate of fire, damage and weapon range is increased in the process. Ore miners, as well as larger vehicles such as Battle Fortresses and Masterminds can not utilize the structure.
The bunker provides protection against ground assaults, but not against air attacks or superweapons (most notably, the Chronosphere can teleport vehicles into and out of tank bunkers). A vehicle must be within the structure before the walls are raised, as there is a slight delay before this is done.
Like the Soviet battle bunker, this structure can be built requiring only a construction yard, and consumes no power. For a sacrifice in cost and ground space, one can garrison a Gattling tank in the bunker to achieve a defense identical to, if not stronger than, a Gattling cannon. Interestingly, such a combination has the same price as a Gattling cannon.
Yuri Prime can capture an empty tank bunker, but if it is loaded, he can only capture the vehicle contained inside.
- Yuri's Revenge patch 1.001: the vehicle inside a tank bunker can no longer be targeted by Tanya's C-4 charges.
- Interestingly, the tank bunker's cameo shows it holding a tank which resembles the Soviet Rhino heavy tank instead of any vehicle in Yuri's arsenal.
