Spc. William Manley, Walter Reed National Military Medical Center combat medic, prepares to give Spc. Katie McConnell, WRNMMC combat medic, an IV during a mass casualty scenario at the final field training exercise of a 10-Day 68W/EMT Sustainment Course in Lorton, Va., Nov. 18, 2016. The course, taught by WRNMMC, provided the fundamentals of Tactical Combat Casualty Care, from the point of injury through evacuation in a tactical environment. Completion of the joint course also satisfied all requirements, as prescribed by the National Registry of Emergency Medical Technicians, for EMT re-certification. (U.S. Air Force photo/Tech. Sgt.
