I was stationed at Ft Myer from 82-85. Those 3rd infantry dudes have got their shit together. I was on a lot of security details at wreath laying ceremonies there (I was military police) and had the good fortune to be invited down to the small onsite barracks that these guys call home while they are at the tomb. To say these guys are dedicated is an understatement. Their regular barracks was right next store to ours, so we would get to see them practice all of the time.
