The Patriot Missile Training Facility in Fort Sill is part of the Defense Base Closure and Realignment (BRAC) Program. The project provided a new facility for the training center, a maintenance building, and a large simulator staging hardpan. The design by Calibre included site grading, site drainage, horizontal control, infrastructure utility, water, and sewer distribution and collection, and erosion control. The project was part of a large training campus that included the Patriot training site, barracks buildings, a large dining hall, and the Stinger training facility.
