Republic of Korea Air Force (ROKAF) Majs. Lee Jong Won and Lee Dong Seop, both ROKAF F-16D Fighting Falcon pilots, ensure their equipment is secured prior to the launch of a RED FLAG-Alaska (RF-A) 15-3 sortie, Aug. 11, 2015 from Eielson Air Force Base, Alaska. Units from across the Department of Defense and allied forces have utilized the Joint Pacific Alaska Range Complex’s 67,000 square miles of airspace for RED FLAG-Alaska since 2006 because it is the largest instrumented air, ground and electronic combat training range in the world.
