U.S. Air Force Capt. Dale Weller, 14th Fighter Squadron pilot from Misawa Air Base, Japan, finishes the post-flight checklist. On average, all four DOD services, including their National Guard and reserve components, participate in two Green Flag exercises each year. Air forces of other countries participate in one or more designated coalition exercises annually. Green Flag exercises provide critical joint training for approximately 75,000 joint and coalition personnel per year. This includes 3,000 sorties, 6,000 flight hours, and the expenditure of over 700,000 pounds of live and training ordnance.
