In an ivory tower
Tracy Brittan, center, 2nd Operations Support Squadron watch supervisor, discusses training records with Staff Sgts. Katelyn Vargas and Nicole Depew, 2nd OSS watch supervisors, on Barksdale Air Force Base, La., July 11, 2013. Airmen begin a year-long training process as watch supervisors once they attain the rank of Staff Sergeant, enabling them to supervise all positions within the control tower, separate arrivals and departures and provide advice in unsafe situations.
