U.S. Marines with the Marine Corps Drum and Bugle Corps perform during a sunset parade at the Marine Corps War Memorial, Arlington, Va., July 7, 2015. Retired Marine Corps Chief Warrant Officer 4 Hershel “Woody” Williams was the guest of honor for the parade and Lt. Gen. Ronald L. Bailey, deputy commandant of Plans, Policies, and Operations, was the hosting official. Since September 1956, marching and musical units from Marine Barracks Washington, D.C., have been paying tribute to those whose“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.
