U.S. Air Force Master Sgt. Elroy Williams, 633rd Force Support Squadron community programs manager, places a rose on a POW/MIA dedication table in the Crossbow Dining Facility at Langley Air Force Base, Va., Nov. 25, 2014. The single rose is to remind people of the families of missing Service members, who maintain faith in their return. There are more than 83,000 Americans still unaccounted for throughout the Department of Defense; nearly 1,500 of those are Airmen.
