Spc. Jillian L. Zaniewski, a U.S. Army Reserve human resource specialist assigned to Task Force 76 out of Salt Lake City, works on personnel actions during Vibrant Response 17 at Camp Atterbury, Ind., May 7, 2017. Vibrant Response 17 is an annual command post exercise that simulates the detonation of a nuclear bomb in a major city within the United States. This year it was integrated with Guardian Response 17 at Muscatatuck Urban Training Center, Indiana. The exercises enable emergency response organizations, both civilian and military, to integrate and provide relief during a catastrophic disaster. (U.S. Army Reserve Photo by Sgt. Stephanie Ramirez)
