The active duty 388th and Reserve 419th Fighter Wings conducted an F-35A Combat Power Exercise at Hill Air Force Base, Utah, Jan. 6, 2020. The exercise, which was planned for months, demonstrated their ability to employ a large force of F-35As -- testing readiness in the areas of personnel accountability, aircraft generation, ground operations, flight operations, and combat capability against air and ground targets. A little more than four years after receiving their first combat-coded F35A Lightning II aircraft, Hill's fighter wings have achieved full warfighting capability. (U.S. Air Force photo by R.
