A permanent guard is mounted at the Tomb of the Unknown Soldier at Arlington National Cemetery in Arlington, VA, near Washington, DC. This is performed by a single member of the 3rd U.S. Infantry Regiment, who marches along a 63-foot walkway in exactly 21 paces, before turning to face the tomb for exactly 21 seconds, turning to face the opposite direction for another 21 seconds, and then retracing his steps to repeat the process. Each turn the guard makes is precise and is instantly followed by a loud click of the heels as he snaps them together. The guard is changed every half hour during daylight in the summer, and every hour during daylight in the winter and every two hours at night (when the cemetery is closed to the public), regardless of weather conditions.
A guard has been on duty at the site continuously, 24 hours a day, 7 days a week, since July 2, 1937.
