Veterans from all the nation's wars are buried in the cemetery, from the American Revolution through the Iraq and Afghanistan. The Tomb of the Unknowns is the most symbolic site at Arlington Cemetery. The Tomb is guarded 24-hours a day, regardless of climatic conditions, by soldiers from the Army's U.S. 3rd Infantry, "The Old Guard." While guarding the Tomb, the sentinels take 21 steps before turning and facing the Tomb for 21 seconds. This corresponds to the 21-gun salute, America's highest military honor. |
