U.S. Air Force Staff Sgt. Christian Fischer, a tactical aircraft maintenance specialist with the Wisconsin Air National Guard's 115th Fighter Wing, assists an F-35A Lightning II pilot with preflight tasks February 13, 2024, during a Weapon System Evaluation Program exercise at Tyndall Air force Base, Florida. The Combat Archer exercise was a formal evaluation of the unit's ability to conduct air-to-air live fire missions. Airmen were given the opportunity to train on tasks and skills that they don't perform at their home unit such as unrestricted takeoffs and loading live ammunition onto the airframe.
