Scarlett Johansson boots morale (and a whole lot more) for nearly 600 troops at Camp Buehring, Kuwait in the Persian Gulf.

The 23-year-old bombshell entertained service officers as part of a USO/Army Morale Welfare Recreation entertainment tour. Scarlett posed for photos and signed autographs for eager troops.

"It's important to give people a piece of home and to boost morale," Johansson said about her visit. "Everybody out here is risking everything, giving us one of the biggest gifts they can. I want to be out here to support them."
