After the ‘U.S. Air Force’ was established as a separate branch of service, the ‘Air Force Reserve’ was born. Its mission is to provide combat-ready forces to ‘Fly, Fight and Win.’ Reservists play a crucial part in the Department of Defense’s strategy for manpower, global reach, and military flexibility. This day celebrates those who have taken the courageous decision to answer the call of duty. They embody the values of integrity, service before self, and excellence that deserves to be celebrated not just for a day but the whole year-round.
