U.S. Marine Corps Staff Sgt. Codie L. Williams, ceremonial bugler with the U.S. Marine Corps Drum and Bugle Corps, plays Taps during the sunset parade at the Marine Corps War Memorial, Arlington, Va., May 26, 2015. Since September 1956, marching and musical units from Marine Barracks Washington, D.C., have been paying tribute to those who's "uncommon valor was a common virtue" by presenting sunset parades in the shadow of the 32-foot high figures of the United States Marine Corps War Memorial.
