Columbus Air Force Base Airmen stand at attention while the flag is folded during a Memorial Day retreat ceremony on base, May 22, 2014. Formerly known as Decoration day, the men and women who died while serving in the United States Armed Forces are remembered every year on the final Monday of May. Memorial Day originated after the American Civil War to commemorate the Union and Confederate soldiers who died. (U.S. Air Force photo/ Sharon Ybarra)
