What about it? The army group?
It is the 1st sustainment command theater. They are in the formation of their patch. Which is behind them on the wall that is always cropped out of this picture. The white arrow on the patch points to what would be 10:30, signifying the mission will be accomplished before the 11th hour. Any more questions?
