The Sentinels of the Tomb of the Unknown Soldier stand watch 24 hours a day, 365 days a year, in any weather. Sentinels, who volunteer for this post, are considered the elite of the elite 3rd U.S. Infantry Regiment (The Old Guard), headquartered at nearby Fort Myer, Virginia. After members of the 3rd U.S. Infantry Regiment become ceremonially qualified, they are eligible to volunteer for duty as Sentinels at the Tomb. If accepted, they are assigned to Company E of The Old Guard. Each soldier must be in superb physical condition, possess an unblemished military record and be between 5 feet, 10 inches and 6 feet, 4 inches tall for men or 5 feet, 8 inches and 6 feet, 2 inches tall for women, with a proportionate weight and build. Would-be Tomb Guards must first undergo an interview and a two-week trial. During the trial phase, they memorize seven pages of Arlington National Cemetery history. This information must be recited verbatim in order to earn a “walk.” If a soldier passes the first training phase, “new soldier” training begins. New Sentinels learn the history of Arlington National Cemetery and the grave locations of nearly 300 veterans.They learn the guard-change ceremony, the manual of arms, and methods for keeping their uniforms and weapons in immaculate condition. The Sentinels must pass multiple tests to earn the privilege of wearing the silver Tomb Guard Identification Badge. First, they are tested on their manual of arms knowledge, uniform preparation and walks. Then, they take the badge test, consisting of 100 randomly selected questions from the 300 items memorized during training. The would-be badge holder must get more than 95 % correct. The Tomb Guard Identification Badge is a temporary award until the badge-holding Sentinel has honorably served at the Tomb of the Unknown Soldier for nine months. At that time, the award can become a permanent badge, which may be worn for the rest of a military career. The silver badge is an upside-down, laurel-leaf wreath surrounding a depiction of the Tomb’s front face, the words “Honor Guard,” and figures representing Peace, Victory and Valor. Over 600 Tomb Guards have earned the badge since the 1950s.
