The Combat Support Wing proof-of-concept capstone exercise developed by the Air Force Installation and Mission Support Center and hosted by Air Combat Command’s 4th Fighter Wing at Seymour Johnson Air Force Base, North Carolina, tested the ability of three teams of about 30 Airmen each to establish and operate an airfield in an austere environment. They had to defend the base and refuel and rearm F-15E Strike Eagle’s using multifunctional skills they learned during training events over the past month.
