United States Marines decontaminate a multinational hazardous materials response team during a simulated downed aircraft mass casualty/hazardous material exercise March 24, 2015, during Eagle Resolve 2015. The exercise affords 29 partner nations the opportunity to address the regional challenges associated with asymmetric/unconventional warfare in a multi-national environment. This is the Government of Kuwait's first time hosting Eagle Resolve, which is the premiere Arabian Peninsula/Gulf Region exercise between the United States, Gulf Cooperation Council nations and other international partners.
