Defense Secretary Ash Carter speaks to Airmen returning from deployment at Nellis Air Force Base, Nev., Feb. 4, 2016. On his way to depart the base, Carter noticed a C-5 Galaxy where Airmen were coming off the aircraft, returning from deployment. So, he took a 20-minute detour to personally welcome home all of the returning Airmen. (U.S. Air Force photo by Staff Sgt. Siuta B. Ika)
