U.S. Marines with Marine Barracks Washington perform during a sunset parade at the Marine Corps War Memorial, Arlington, Va., July 28, 2015. U.S. Navy Adm. Harry B. Harris, U.S. Pacific Command, was the guest of honor for the parade, and Gen. John M. Paxton, assistant commandant of the Marine Corps, 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.
