In the Army they have what are known as Warrior Transition Brigades. The purpose of these units is to care for service members who have been wounded in the Global War on Terrorism. Recently these units were authorized to have their own flag. The flag for WRAMC (Walter Reed Army Medical Center) was flown over the ISS. In the photo the flag is draped over the podium.
