A member of The Old Guard salutes the remains of an honored soldier and veteran at Arlington National Cemetery, while The Arlington House shines in the distance under the afternoon sun. The 3d U.S. Infantry, 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. We are humbled to capture moments like this each and every service we cover here with Arlington Media.
