Through sleet, snow or dark of night, these soldiers march and stand on guard.
Known generally as the Tomb of the Unknown Soldier, the official name is the Tomb of the Unknowns.
The soldiers were undaunted by this season’s first snowstorm.

Arlington stopped bus tours because of the weather, but the guards remained on duty.
They keep a 24-hour vigil at the Tomb of the Unknowns, 365 days a year.
Members of the 3rd U.S. Infantry Regiment, traditionally known as “The Old Guard,” have stood on guard at the Tomb since they took over the duty in 1948.
The oldest active-duty infantry unit in the Army, “The Old Guard” has served the Army since 1784.
Soldiers volunteer for the Sentinel duty.
In order to qualify to be a Sentinel soldiers have to go through training, including learning how to march and understanding the history of the site.
They even have to learn how to break down their uniforms and recreate them.
It can take the average Sentinel eight hours to prep their uniform for the next work day.
The guard is changed every half hour in the summer and every hour in the winter.
Currently, Sentinels work 24 hours on, 24 hours off, 24 hours on, 24 hours off, 24 hours on, 96 hours off.
All out of respect for the Unknowns.
