U.S. Air Force members from the 145th Maintenance Group stand in formation during a ramp formation held at the North Carolina Air National Guard Base, Charlotte Douglas Intl. Airport May 3, 2015. A ramp formation is when units assigned to the 145th Airlift Wing form up quarterly to honor award winners and medal recipients. It also gives U.S. Air Force Col. Marshall Collins, 145th Airlift Wing commander, an opportunity to address his airmen. (U.S. Air National Guard photo by Staff Sgt. Julianne M. Showalter, 145th Public Affairs/Released)
