Barnhardt, New London, N.C., Sept. 10, 2016. Puckett is an instructor assigned to the 145th Operations Support Squadron. The airmen are pilots and crew chiefs assigned to the 145th Operations Group. Hands-on familiarity with all of the emergency equipment kept on the C-130 is essential to build muscle memory in times of crisis. Air National Guard photo by Staff Sgt. Julianne M. Showalter
