Lt. Col. Chetan Kharod, 24th Special Operations Squadron surgeon, speaks during the Tactical Combat Casualty Care course with little discomfort after he inserted a nasopharyngeal airway on himself Nov. 9, 2012 at Hurlburt Field, Fla. The underlying intent of the course is to provide hands-on skills in tourniquet application, needle thoracotomy, airway management, pain control, and fracture management.
