English: U.S. Army Pacific and U.S. Army Corps of Engineers Soldiers along with other support elements, work on erecting a solar shade canopy during the setup of a humanitarian aid and disaster relief event for Rim of the Pacific training exercise at Ford Island, July 7. Besides providing shade and energy, the solar shade reduces the heat signature of the equipment setup underneath it. Twenty-two nations, more than 40 ships and submarines, about 200 aircraft and 25,000 personnel are participating in Exercise RIMPAC from June 26 to Aug. 1 in and around the Hawaiian Islands and Southern California. The world's largest international maritime exercise, RIMPAC provides a unique training opportunity that helps participants foster and sustain the cooperative relationships that are critical to ensuring the safety of sea lanes and security on the world's oceans. RIMPAC 2014 is the 24th exercise in the series that began in 1971. (U.S. Army photo by Staff Sgt. Kyle J. Richardson, USARPAC PAO)
