UNSC Vehicle Depot

A Vehicle Depot contains the heavy equipment and crew to assemble vehicle kits. Hydraulic cranes serve as the muscle to move everything from Cobra chassis, Scorpion armored plates, and the impressive selection of weaponry that these vehicles can bring to bear. The parts may take awhile to arrive, but when the engine from a new Scorpion fires up in the Vehicle Depot, the rumble is felt all across the base.

Background
It appears to (quickly) manufacture its vehicles underground and transport them to the surface, via a movable ramp. It is capable of building and reinforcing the UNSC's powerful ground based Corps with Wolverines, Cobras, and Scorpion Tanks. Vehicles are stored as prepackaged "kits", and quickly assembled via the structure's internal assembly equipment and personnel, before being released for use in combat.

The Covenant equivalent is the Factory. It costs 150 resources and requires a tech level of 2.
