U.S. Army Reserve Sgt. Arenda Wood with the 7218 Medical Support Unit, based in Louisville, Ky., prepares moulage on Indiana Air National Guard role players during Guardian Response 19 at Camp Atterbury, Ind., April 30, 2019. Moulage is the art of applying mock injuries to role players or mannequins to help provide realistic medical and emergency response training scenarios. More than 9,000 Soldiers from across the country are participating in Guardian Response 19, a multi-component training exercise that validates U.S. Army units’ ability to support the Defense Support of Civil Authorities in the event of a Chemical, Biological, Radiological and Nuclear catastrophe.
