Sgt. Jacob Davis, Bravo Battery, 1-148th Field Artillery, Idaho National Guard, works on a puzzle at FOB Prosperity in the International Zone in Baghdad, Iraq, February 5, 2011. His team, part of the Quick Reaction Force for what was once called the Green Zone, has had a very quiet time - they haven't been called out since their arrival five months ago. They've completed 20 puzzles since then - some of them mounted on the wall behind him to the left. The U.S. embassy is generally the only target anymore - a few mortars a month - due to it's easy location on the Tigris river.
