Starship Troopers: Terran Command – How to Deploy a Building
To deploy a building, left-click on an empty Deployment Platform, and a list of available buildings will appear in the Control Grid. If you have enough War Support and your Battle Tier Level is high enough, you will be able to call down the new building immediately and start deploying new units. Buildings that have already been deployed will have a green checkmark and clicking on their icon will focus the camera on their location.
A building can’t be deleted but it can be converted to a different one in the same Battle Tier as long as you don’t control any units that are supported by it. Since buildings cannot be disbanded or destroyed, the War Support cost is permanent. You may want to not deploy every possible building if you intend to build multiple advanced units. Additionally, only one building of each type can be deployed at a time. Therefore if you lose control of a base, you will also lose access to the unit types that were supported by that base until you recapture it.
