U.S. Air Force Col. Laura Brodhag, 355th Aerospace Medical Squadron commander, and Staff Sgt. Covito Redman, 355th Medical Support Squadron, place tags on victims of a simulated aircraft crash during Angel Thunder at Davis-Monthan Air Force Base, Ariz., April 13, 2013. Victims' tags identified them based on the severity of their simulated injuries so that medical personnel could address the more severe injuries first.
