U.S. Air Force Staff Sgt. Jason Anders, 31st Maintenance Squadron aircraft fuels system craftsman, teaches Bulgarian air force members hydrazine emergency response procedures on a U.S. Air Force F-16 Fighting Falcon assigned to the 555th Fighter Squadron during exercise Thracian Star 21 at Graf Ignatievo Air Base, Bulgaria, July 20, 2021. This exercise required all levels of a squadron to deploy small teams of Airmen and aircraft for a short amount of time to hone their skills. Thracian Star 21 also enhanced their ability to rapidly deploy to a remote location, establish command and control and deliver lethal airpower more effectively and efficiently anywhere in the world.
