Check out this amazing photograph of a member of the 3rd U.S. Infantry Regiment guarding the Tomb of the Unknowns (also called the Tomb of the Unknown Soldier) at Arlington National Cemetery as Hurricane Irene battered the region. The 3rd U.S. Infantry Regiment, also known as The Old Guard, is the same group responsible for "flags in," making sure each and every grave at Arlington National Cemetery has an American flag for Memorial Day.
