Staff Sgt. Dustin White, a 28th Contracting Squadron contract supervisor, works on a contract during a weeklong exercise at Ellsworth Air Force Base, S.D., May 13, 2020. The exercise simulated what contracting personnel may experience while deployed, and involved a white cell which created scenarios that contractors within the blue cell had to react to and execute.
