As noted earlier, the photo of the guards at the Tomb of the Unknown Soldier making going viral on Facebook is actually from September, not a picture of the the soldiers guarding the Tomb today.

The 3d U.S. Infantry Regiment (The Old Guard) posted the real photo of the Spc. Brett Hyde, Tomb Sentinel, 3d U.S. Infantry Regiment - the guard currently on duty - on their Facebook page, after the idea went viral.
