I recommend looking up the Arlington national cemetery page and see if it has a virtual tour available.
During the changing of the guard you are to remain silent. Go watch some videos of the changing of the guard and what happens to people who disrespect the tomb.

Document the requirements the men have to meet to be eligible for this duty
Please take time to look at the history of the "Old Guard" the 3rd Infantry Regiment that guards the site
