Soldiers were first placed at the Tomb of the Unknown Soldier in 1926. Their primary responsibility was to prevent people from climbing or stepping on the Tomb. Beginning in 1937, guards were stationed there 24 hours a day. Since 1948, soldiers from the 3rd U.S. Infantry Regiment, called “The Old Guard,” have protected the Tomb. The soldiers are replaced in an elaborate changing-of-the-guard ceremony that occurs every hour or half hour, depending on the day.
Guarding the Tomb of the Unknown Soldier is a symbol of respect for those who have served and died without recognition. The presence of guards ensures that the site remains a dignified and solemn place, reflecting the nation’s gratitude and reverence for its fallen heroes. The guards have been known to reprimand visitors who fail to maintain the expected atmosphere of silence and respect.
