Tradition has dictated that the tomb remain guarded at all times. There has been at least one soldier watching over the tomb since the Army’s 3rd Infantry Regiment took over the mission a few years after the end of World War II. A sentinel is present 24 hours a day, seven days a week, 365 days a year, including holidays.
When it rains, the guard stands under a green nylon tent that’s used for wreath-laying ceremonies to shield him from the inclement weather. As the winds start to pick up Saturday afternoon and into Sunday, he will then, if necessary, move into what’s known as the “Memorial Display Room,” essentially a marble enclosure that holds plaques and other honoraria dedicated to the unknown soldiers. From there, the guard will have “a continual line of sight on the tomb,” Miller said.
