<P> The tomb guards are soldiers of the United States Army . The first military guards were troopers from the 3rd Cavalry , `` Brave Rifles '' , who were posted nearby on Fort Myer . Since April 6 , 1948 , ( known then as `` Army Day '' ) , when the regiment was reactivated , it has been guarded by soldiers from 3rd Infantry Regiment , `` The Old Guard '' . The Old Guard is also posted to Fort Myer , Virginia , adjacent to Arlington National Cemetery . It is considered one of the highest honors to serve as a Sentinel at the Tomb of the Unknowns . Fewer than 20 percent of all volunteers are accepted for training and of those only a fraction pass training to become full - fledged Tomb Guards . This attrition rate has made the Tomb of the Unknown Soldier Guard Identification Badge the second least - awarded qualification badge of the United States military ( the first being the Astronaut Badge ) . </P>
