Airmen from the 7th Air Support Operations Squadron Tactical Air Control Party do memorial pushups before starting the 24-hour Remembrance Run at Fort Bliss, Texas, March 26, 2015. Each year, TACP units from across the Air Force run for 24-hours to honor the TACP members who have made the ultimate sacrifice. Each unit raises money and collects donations that go toward the TACP foundation. (U.S. Air Force photo by Airman 1st Class Emily A. Kenney/Released)
