Sgt. Stephanie L. Peavy of Machesney Park, Ill., and Spec. John G. Matsoukas of Chicago, both members of the 244th Army Liaison Team based in Chicago, tests the capability of an operating system being tested by the U.S. military for possible fielding of new equipment during an annual training exercise called Coalition Warrior Interoperability Demonstration. CWID 2011 spans five U.S. locations and more than 20 coalition partners worldwide. The participating technologies were approved based on how well they address capability gaps and evaluates how well they assists in the exchange of information between coalition partners, military services, government agencies, first responders and U.S. combatant commanders.
