The Republic of Korea Air Force participates in Red Flag training - a multinational exercise designed to enable Allied forces to fight together in the most realistic way possible. Held at Nellis Air Force Base, Nevada, the two-week exercise involves around 1,200 aircraft flying over 20,000 sorties. Although the ROKAF has participated in Red Flag twice before, this was their first opportunity to put their new Boeing F-15K Slam Eagles to the test.
