"The Old Guard" - Changing of the Guard
Tomb of the Unknown Soldier
Arlington Cemetery, Arlington, VA
The Arlington Cemetery website states that "The Tomb of the Unknowns (also known as the Tomb of the Unknown Soldier) is guarded 24 hours a day, 365 days a year, and in any weather by Tomb Guard sentinels. Sentinels, all volunteers, are considered to be the best of the elite 3rd U.S. Infantry (The Old Guard), headquartered at Fort Myer, VA."
The requirements to earn this duty are extremely tough, and only the very best - less than 20% of all applicants - make it through training and testing. Approximately 525 Tomb Guard badges have been awarded in the past 51 years -- to earn the badge you need to serve in the role for a certain number of months, it is not automatically given when you begin the duty. Only three of those have been given to women. It is considered one of the highest honors of duty to be a Tomb Guard, and it is the only badge awarded by the Army that can be revoked, even after the soldier has left the Army, for any act that would bring discredit upon the Tomb of the Unknowns. (Nine have been revoked to date.)
The Tomb has been guarded 24/7 since July 2, 1937, no matter how severe the weather, and the duty is always performed the same - even when the cemetery is closed and there is nobody there to observe them.
