Old Guard Silences Laughing Tourists
The 3rd U.S. Infantry, also known as the Old Guard, serve as sentinels in Arlington National Cemetery for the Tomb of the Unkown Soldier.
There is a very rigorous training process to be selected, and the Old Guard take their jobs very seriously.
So when tourists start laughing and talking during a routine patrol, one soldier immediately puts them in their place.
