Photos have emerged on Facebook of a lone Tomb Sentinel, 3d U.S. Infantry Regiment (The Old Guard), walking his tour in humble reverence at the Tomb of the Unknown Soldier during Hurricane Irene in Arlington National Cemetery this afternoon. Members of The Old Guard have guarded the Tomb “every second, of every day regardless of weather or holidays” since April 6, 1948 (The Society of The Honor Guard of the Tomb of the Unknown Soldier began the first 24-hour guard on July 2, 1937).
