Tech Oil Derrick (Generals)

Oil Derricks were a common sight on the oil-drenched battlefields of the GLA war. They were also one of the most significant civilian buildings that could be captured by military forces. By researching the Capture Building upgrade at the Barracks, commanders from any faction could order their infantrymen to take these structures. Once captured, an Oil Derrick delivered a one-off financial windfall followed thereafter by a steady, near-unlimited stream of revenue. The endless cash provided by the capture of an Oil Derrick made these buildings hot pieces of real estate for all generals, and they provided the flashpoint for many a vicious skirmish. Once captured an Oil Derrick was often zealously protected, lest it be captured by the enemy or simply destroyed.

A favourite GLA tactic was to purchase the Booby Trap upgrade for their Rebel fighters, and then order their Rebels to place said explosives on oil derricks to prevent their capture. Dr. Thrax's Oil Derricks, those funding his campaign, were covered in them, providing a tedious (yet often dangerous) task for the opposing US forces.
