This is the 388th Fighter Wing's second Red Flag with the F-35A, America's most advanced multi-role fighter, which brings game-changing stealth, lethality and interoperability to the modern battlefield. Red Flag is the Air Force's premier combat exercise and includes units from across the Air Force and allied nations. (U.S. Air Force photo by R. Nial Bradshaw)
