First responder
After checking on the first victim, Sgt. Sean Lewis, 6th Ranger Training Battalion medic, rushes past the wreckage to the next victim Oct. 1 during the 6th RTB’s annual mass casualty exercise. The exercise was to examine how effective the battalion responds as a group and how well it communicates and works with outside emergency agencies in the event of a catastrophe on Eglin's range.
