Base

 is a building of the Marines.

Background
It costs 5000 Resources to upgrade from Headquarters to a Base, provided a Barracks and MASH Facility exist. The Base holds 30,000 Resources, 100 Butanium, and 100 Supplies. An Enlistee with potential can be trained to become a Techie at a Base, once the research has been completed. Extended training can be given to any valid unit at a Base, and Invention skill levels are advanced here through research. In addition, this structure is required in order to build an Uplink, Kennels, and Firing Range.
