Inga Keithly (right), a San Diego, Calif., native and dentist attached to 2nd Maintenance Battalion, Combat Logistics Regiment 25, 2nd Marine Logistics Group, gives a dental exam to a Marine with Golf Battery, 10th Marine Regiment, 2nd Marine Division near the firing line during Rolling Thunder, a biannual training exercise at Fort Bragg, N.C., May 9, 2014. Keithly devised and executed a plan to bring dental exams to the Marines on the front lines of the operation, where the constant work of keeping the guns firing prevented personnel from reaching the dental clinic set up for the exercise.
