First, this answer will be updated in a couple of weeks. As I write it in January 2013, the president is about to begin his second term and he will be making changes in his cabinet, which frequently happens in a president's second term. But as for who has served in Mr. Obama's first term, among his fifteen cabinet members were the Secretary of State (Hillary Clinton), Secretary of Defense (Leon Panetta), Secretary of the Treasury (Timothy Geithner), Secretary of the Interior (Kenneth Salazar), Secretary of Agriculture (Thomas Vilsack), Secretary of Labor (Hilda Solis) and Secretary of Transportation (Ray LaHood).
Obama never served in the military.
