TOMB OF THE UNKNOWN SOLDIER...Arlington National Cemetery in Virginia
The site is guarded around the clock, every day of the year, in all types of weather, by specially trained members of the Third United States Infantry Regiment (also known as the “Old Guard“). The Sentinels who guard the Tomb must be exemplary in discipline, dress, and bearing; thoroughly knowledgeable with the history of their unit, the Tomb of the Unknowns, Arlington National Cemetery (and those interred there), and the U.S. Army; and able to execute a variety of ceremonial rites flawlessly and with precision.
