Tomb Guards Reprimanding Visitors at Arlington

This is a compilation of all the videos I've found of sentinels acting to keep visitors quiet and respectful--and they are hard to come by. The sentinels at Arlington Cemetery's Tomb of the Unknown Soldier (from the 3rd Infantry Regiment, US Army) aren't just automatons! They actively guard the atmosphere at the tomb, telling visitors to remain respectful by quieting down or by staying off restricted areas. I've added subtitles to the video for the full effect of the guards' "third-person" warnings. via
