In this image, members of the 136th Military Police battalion, part of Joint Task Force 136 (Maneuver Enhancement Brigade), conduct medical evacuation training during Operation Joint Eagle at Camp Gruber in Muskogee, Oklahoma, September 17, 2013. The exercise tests the response times, life-saving capabilities, and interagency cooperation of the unit's Homeland Response Force mission. Throughout the week of September 13 through the 20, service members responded to simulated disaster scenarios such as an F-5 tornado, a man-made explosion, and chemical outbreaks throughout the area.
