Some very impressive restrictions those people must endure and I know I couldn't do it. That is some serious discipline.
Small note on the hurricane guard -- "A contingency plan had been established that if winds reached 120 mph the guards could retreat from their usual exposed-to-the-elements posts in the tomb plaza to take up positions in trophy room, which is above the tomb plaza and has a clear view of the sepulcher. (The Tomb of the Unknowns is a small box-like white building situated in an open area close to the middle of the cemetery.) This plan was not put into effect."
Damn fine men.
