An F-15E Strike Eagle, takes off during Exercise Green Flag April 24 at Nellis Air Force Base, Nev. Green Flag is an Air Combat Command pre-deployment exercise for units who perform close-air support. The training exercise, which began April 19 and runs through May 4, mirrors many of the irregular warfare-conditions the aircrews will see while fighting the war on terrorism. During Green Flag, aircrews will try to learn better ways to employ airpower within an irregular warfare environment. The F-15E is from Seymor Johnson AFB, N.C. (U.S. Air Force photo/Master Sgt.
