The guard is changed every hour on the hour October 1 to March 31 in an elaborate ritual. From April 1 through September 30, there are more than double the opportunities to view the change because another change is added on the half hour and the cemetery closing time moves from 5:00 to 7:00 p.m.
An impeccably uniformed relief commander appears on the plaza to announce the Changing of the Guard. Soon the new sentinel leaves the Quarters and unlocks the bolt of his or her M-14 rifle to signal to the relief commander to start the ceremony. The relief commander walks out to the Tomb and salutes, then faces the spectators and asks them to stand and stay silent during the ceremony.
The relief commander conducts a detailed white-glove inspection of the weapon, checking each part of the rifle once. Then, the relief commander and the relieving sentinel meet the retiring sentinel at the center of the matted path in front of the Tomb. All three salute the Unknown who have been symbolically given the Medal of Honor. Then the relief commander orders the relieved sentinel, "Pass on your orders." The current sentinel commands, "Post and orders, remain as directed." The newly posted sentinel replies, "Orders acknowledged," and steps into position on the black mat. When the relief commander passes by, the new sentinel begins walking at a cadence of 90 steps per minute.
The Tomb Guard marches 21 steps down the black mat behind the Tomb, turns, faces east for 21 seconds, turns and faces north for 21 seconds, then takes 21 steps down the mat and repeats the process. After the turn, the sentinel executes a sharp "shoulder-arms" movement to place the weapon on the shoulder closest to the visitors to signify that the sentinel stands between the Tomb and any possible threat. Twenty-one was chosen because it symbolizes the highest military honor that can be bestowed -- the 21-gun salute.
Duty time when not "walking" is spent in the Tomb Guard Quarters below the Memorial Display Room of the Memorial Amphitheater where they study cemetery "knowledge," clean their weapons and help the rest of their relief prepare for the Changing of the Guard. The guards also train on their days off.
The Guards of Honor at the Tomb of the Unknown Soldier are highly motivated and are proud to honor all American service members who are "Known But to God."
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 Regiment (The Old Guard), headquartered at Fort Myer, Va.
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, with a proportionate weight and build. An interview and a two-week trial to determine a volunteer's capability to train as a tomb guard is required.
During the trial phase, would-be sentinels memorize seven pages of Arlington National Cemetery history. This information must be recited verbatim in order to earn a "walk." A walk occurs between guard changes. A daytime walk is one-half hour in the summer and one hour in the winter. All night walks are one hour.
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 and the manual of arms that takes place during the inspection portion of the Changing of the Guard. Sentinels learn to keep their uniforms and weapons in immaculate condition.
The sentinels will be tested to earn the privilege of wearing the silver Tomb Guard Identification Badge after several months of serving. First, they are tested on their manual of arms, uniform preparation and their walks. Then, the Badge Test is given. The test is 100 randomly selected questions of the 300 items memorized during training on the history of Arlington National Cemetery and the Tomb of the Unknown Soldier. The would-be badge holder must get more than 95 percent correct to succeed.
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 be made a permanent badge, which may then be worn for the rest of a military career. The silver badge is an upside-down, laurel-leaf wreath surrounding a depiction of the front face of the Tomb. Peace, Victory and Valor are portrayed as Greek figures. The words "Honor Guard" are shown below the Tomb on the badge.
There are three reliefs, each having one relief commander and about six sentinels. The three reliefs are divided by height so that those in each guard change ceremony look similar. The sentinels rotate walks every hour in the winter and at night, and every half-hour in the day during the summer. The Tomb Guard Quarters is staffed using a rotating Kelly system. Each relief has the following schedule: first day on, one day off, second day on, one day off, third day on, four days off. Then, their schedule repeats.
The 3rd U.S. Infantry Regiment, traditionally known as "The Old Guard," is the oldest active-duty infantry unit in the Army, serving our nation since 1784.
The Old Guard is the Army's official ceremonial unit and escort to the president, and it also provides security for Washington, D.C., in time of national emergency or civil disturbance.
The unit received its unique name from Gen. Winfield Scott during a victory parade at Mexico City in 1847 following its valorous performance in the Mexican War. Fifty campaign streamers attest to the 3rd Infantry's long history of service, which spans from the Battle of Fallen Timbers to World War II and Vietnam.
Since World War II, The Old Guard has served as the official Army Honor Guard and escort to the president. In that capacity, 3rd Infantry soldiers are responsible for the conduct of military ceremonies at the White House, the Pentagon, national memorials and elsewhere in the nation's capital. In addition, soldiers of The Old Guard maintain a 24-hour vigil at the Tomb of the Unknown Soldier, provide military funeral escorts at Arlington National Cemetery and participate in parades at Fort Myer and Fort Lesley J. McNair.
Along with these duties, The Old Guard presents historic theatrical productions to audiences in the Washington, D.C., area. One show, "Twilight Tattoo, " is presented weekly during the summer on the Fort Myer portion of Joint Base Myer-Henderson Hall. The show is free and open to the public.
The Old Guard annually participates in more than 6,000 ceremonies, an average of 16 per day.
Despite this arduous schedule, The Old Guard continuously prepares for its security and infantry missions by conducting year-round training, culminating in a rigorous evaluation of unit tactical proficiency. Because of this, all soldiers are as familiar with traditional infantry or military-police duties as they are with ceremonial duties.
The black-and-tan "buff strap" worn on the left shoulder by each member of the 3rd Infantry is a replica of the knapsack strap used by 19th-century predecessors of the unit to display its distinctive colors and distinguish its members from other Army units. The present buff strap continues to signify an Old Guard soldier's pride in personal appearance and precision performance that has marked the unit for 200 years.
A further distinction of The Old Guard is the time-honored custom of passing in review with fixed bayonets at all parades. This practice, officially sanctioned by the War Department in 1922, dates to the Mexican War in 1847 when the 3rd Infantry led a successful bayonet charge against the enemy at Cerro Gordo. Today, this distinction is still reserved for The Old Guard alone.
