Sentinels, assigned to the 3d U.S. Infantry Regiment (The Old Guard), stand guard at the Tomb of the Unknown Soldier at Arlington National Cemetery, Va., Jan. 22, 2016, as a record breaking snow storm hits the Washington, D.C. area. The Tomb Guards maintain a constant vigil at the Tomb no matter the weather conditions and has done so in an unbroken chain ever single second of the past 48 years.
