Soldiers with the 44th Chemical Company, 2nd Chemical Battalion, 48th Chemical Brigade, push a litter on the conveyer belt to the next station during the mass casualty decontamination exercise March 19. The casualties, civilian role players, wore mulage makeup during the exercise to provide a level of difficult for the soldiers, and they help simulate what the soldiers might encounter during an actual catastrophe, said U.S. Army North Command Division Chief James Barkley, from Columbus, Ohio. Mulage makeup is used to create realistic injuries for the purpose of training medical personnel and emergency response teams.
