The U.S. Marine Corps Silent Drill Platoon performs during the sunset parade at the Marine Corps War Memorial, Arlington, Va., June 9, 2015. Retired Col. Harvey C. Barnum Jr., Marine Corps medal of honor recipient, and John Fales Jr., Marine Corps purple heart recipient, were the guests of honor for the parade, and Lt. Gen. James B. Laster, director of Marine Corps Staff, 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.
