Wrightman Base was originally a COG Department Of Health building. However, it was later transformed into a military base, though it still operated as a small-time hospital as Dr. Hayman still worked there. The base was presumably large-scale. It also housed large numbers of armored cavalry in specialized cargo bays for storage, repair and cleaning. It also held a number of aircraft squadrons in the back of the base on a field, including Petrels, King Ravens and Corvas. The base was also one of the main centers for High Command, or the Combat Information Center, where they worked, commanded and controlled units on the field. There were also a number of accommodations for all of the personnel there, including a Main Barracks, a Mess Hall and Emergency Rooms.
