In "This Week in the DoD" for May 4:

President Barack Obama made a surprise visit to Afghanistan, where he signed a ten-year defense agreement between the U.S. and Afghan governments, outlining the two countries' relationship after the combat misison ends there. He also visited troops at Bagram Air Base.

After meetings with his counterpart from the Philippines, Defense Secretary Leon Panetta praised the country in a press conference with Secretary of State Hillary Clinton. He said the historic alliance between the U.S. and Philippines has been instrumental in disrupting al Qaeda activity in the South Pacific.

All this week, wounded, injured and ill troops have been competing in the annual Warrior Games in Colorado Springs, Colo. The annual Olympic-style contest pits teams from each of the military services (as well as a team from the United Kingdom, this year) against each other in friendly competition. First Lady Michelle Obama and Gen. Martin Dempsey, Chairman of the Joint Chiefs of Staff, joined the athletes at the Warrior Games opening ceremony Monday.

May is Military Family Appreciation Month, and we start the month off with a special message from Gen. Dempsey and his wife, Deanie.
