The document contains 20 photos of F-16 aircraft from Eielson Air Force Base in Alaska. The photos show the F-16s participating in training exercises with Mount McKinley visible in the background. Many of the F-16s are painted in aggressor colors to represent hostile forces during the training missions. The captions provide additional context about the 354th Fighter Wing, the 18th Aggressor Squadron, and exercises like Northern Edge that take place in Alaska's large training ranges.
