• Responsible for maintaining the highest standards and traditions of the United States Army and this Nation while keeping a constant vigil at this national shrine
• Prevent any desecration or disrespect directed toward the Tomb of the Unknown Soldier

Millions of Americans annually visit the Memorial Amphitheater to watch these dedicated soldiers of a new generation, dutifully pace 21 steps across a black mat on the west face of the Tomb. It is a time honored ritual, executed with great precision and filled with American pride.

The sentinel marches 21 steps across the black mat, past the final resting places of the Unknown Soldiers of World War I, World War II, Korea, and the crypt of the Unknown Soldier of the Vietnam War.

With a crisp turn, the sentinel turns 90 degrees to face east for 21 seconds.

The sentinel then turns a sharp 90 degrees again to face north for 21 seconds. A crisp "shoulder-arms" movement places the rifle on the shoulder nearest the visitors to signify that the sentinel stands between the tomb and any threat.

After the moment, the sentinel paces 21 steps north, turns and repeats the process.

The practiced cadence is timed so that the sentinel paces at a rate of 90 steps each minute.

As the active sentry nears the conclusion of his walk, a uniformed relief commander enters the plaza to announce the Changing of the Guard. When the sentinel assigned the next walk leaves the guards' quarters, he unlocks the bolt of his M-14 rifle to signify that he is ready to begin the ceremony. The relief commander approaches the tomb, slowly salutes, then faces the visitors and requests silence during the ceremony.

As the new sentinel approaches the relief commander slowly and with great precision, conducts a white-glove inspection of the sentinel's weapon. The two then march to the center of the mat where the duty sentinel stops his walk, and all three men salute the Tomb.

"Pass on your orders." the commander instructs the active sentinel.

"Post and orders, remain as directed." He replies.

"Orders acknowledged." Answers the relieving sentinel, who then steps into position at the center of the black mat. As soon as the relief commander passes, the new sentinel begins his own walk, 21 paces south, turn and pause for 21 seconds, turn and pace 21 steps south, and then repeat the actions without distraction until relieved by the next Changing of the Guards.

Soldiers opt to uphold duty rather than flee storm

Here Rests In Honored Glory An American Soldier Known But To God.

So reads the inscription etched into the white granite tomb that marks the resting place of America's official unknown soldiers. The Tomb of the Unknowns remains one of the United States' most revered sites, a permanent reminder of this country's commitment to honor those who died fighting for its freedom.

Last week, that commitment was upheld in a way some people might not have even noticed or even thought about.

When practically every government employee in Washington was beating a hasty retreat to avoid the aftereffects of Hurricane Isabel, a small group of men decided their commitment to duty, honor and country was more important than personal safety or comfort.

Tomb Guard Sentinels, the elite soldiers of the 3rd Infantry Division chosen to act as guards at the Tomb, opted to sustain their constant vigil at the Tomb of the Unknowns rather than flee the oncoming bad weather. To them it was a matter of honoring their personal and professional obligations to the men and women who served before them

and who serve now-and obviously do not have the luxury of serving their

country only when skies are blue and the sun shines down upon them.

Although the Tomb of the Unknowns is watched over by

Tomb Guards 24 hours a day, 365 days a year regardless of weather conditions, to have soldiers so duty-bound as to ignore their own personal well-being is an example of real patriotism and a real reminder of the sacrifices made to secure the principles of liberty.
