The U.S. Air Force implement a realistic training program called “Red Flag” to improve both pilot air combat skills and survival rate. At Red Flag, pilots are divided into both friendly and hostile forces, with the latter called “Aggressor” which have specially selected pilots at the helm. Making up the core of these “Aggressor” forces are F-16C Block 30, 32, & 42 aircraft which are dressed up as Soviet MiG and Sukhoi aircraft with distinctive blue and brown camouflage patterns. Also, the U.S. Navy's hypothetical enemy force is called “Adversary” and use the F-16N aircraft with training held at their Navy Fighter Weapons School, famously known as “TOPGUN”. Both aircraft have their own individualistic camouflage pattern and contribute to the strategic training of each unit.
