Teresa Halverson admires an Air Force logo-adorned block of billet aluminum during the 919th Special Operations Wing Civic Leader Tour at Duke Field, Fla. April 22. The 919th Special Operations Maintenance Squadron Fabrication Flight, where the block was machined during a training session, was one of several visits that helped educate the civic leaders on the wing’s Citizen Air Commandos and their roles in national defense.
