Command & Conquer: Red Alert 3/Tech buildings

Tech buildings are neutral structures on the battlefield that can be captured by Engineers to provide certain benefits for your armies. Unoccupied tech buildings are always seen with a white flag with a gear symbol on it. Allied and Soviet Commanders cannot build structures near tech buildings, unlike in Red Alert 2.

Oil Derrick
Oil Derricks are perhaps one the the most useful tech structures in the game. When captured, they give a $500 dollar bonus to the first player who captures it and afterwards give out steady income. Oil Derricks can be found on both the land and sea.

Swiss Banks
Similar to Oil Derricks but only available in Geneva. They provide 500 and 5 dollars latter.

NYSE
The New York Stock Exchange Building provides $1,000 bonus and $100 steady income. This building is only in the last Soviet mission in New York.

Garage
When captured, all friendly ground units auto-repair.

Airport
When captured, all friendly aircraft automatically repair.

Hospital
When a Hospital is captured, all infantry units will auto-heal.

Dry Dock
When captured, all ships and things that are in the water will auto-repair.

Radar Outpost
If you capture a Radar Outpost, it will provide a large area of visibility.

Veteran Academy
If captured, all units, even the ones without weapons, gain one rank per deployment. If two are captured all units gain two ranks per deployment. If three are captured all units gain the rank of Heroic.
