Among the chosen military is Staff Sgt. Bria Nelson, an Air Force medical technician, who served in Afghanistan and is now serving at Joint Base Anacostia-Bolling in Washington. She is picked to dance with President Obama.

The dance partners were picked from a list of 50 candidates proposed by military chefs and based on their combat and volunteer experience.

The tradition of dancing with one of guests at an inauguration ball for military families was initiated by President George W. Bush.
