Always training
                Tech. Sgt. Jack Mills, an A-10 jet mechanic assigned to the 917th Maintenance Squadron, works on a TF-34 jet engine during the Unit Training Assembly weekend at Barksdale Air Force Base, La., March 31, 2012. Approximately 2,100 Reserve Airmen call Barksdale home at least one weekend a month in order to maintain their skills in hundreds of job fields, just in case they are called into action to support their local community, state or the United States of America.
