U.S. Air Force Senior Airman Brandon Barksdale, 7th Civil Engineer Squadron firefighter, spots Senior Airman Steven Vermillion, 7th CES firefighter, during a workout May 18, 2015, at Dyess Air Force Base, Texas. The Dyess Fitness Center started a 24-hour fitness program that permits unsupervised facility usage after normal hours of operation. During these hours, the fitness center highly recommends the use of the wingman/buddy concept while working out for safety and accountability.
