Here's how the Old Guard renders honors at Arlington

The U.S. Army’s 3rd Infantry Regiment is the Army’s official ceremonial unit. It escorts the president, conducts ceremonies honoring the Army and its fallen soldiers, and provides a 24-hour honor guard at the Tomb of the Unknowns.

Known as the Old Guard, the unit has served the nation since 1784 and is expected to maintain the highest levels of professionalism and military bearing. Recently, Soldiers Magazine published a video by U.S. Army Staff Sgt. Jedhel Somera of the Old Guard in action during a ceremony at Arlington National Cemetery. Check it out below:
