The Tomb of the Unknown Soldier is Arlington National Cemetery’s most iconic memorial and is guarded 24/7 by the 3rd U.S. Infantry Regiment, known as “The Old Guard.” One of those sentinels was Ethan Morse, who later became a filmmaker and made a documentary and TV series about the lives and mindsets of tomb guards.
