Mr. Marvin Whitfield, top left, a contractor with Six3 Systems briefs U.S. Air Force Reservists during battlefield forensic training on July 26, 2013 at March Air Reserve Base, Calif. A mobile training team comprised of government contractors from Six3 Systems taught 38 airmen, two sailors and one Marine how to collect and process biometric evidence in a battlefield environment. Only 2 percent of the entire U.S. military has ever received this one-of-a-kind training. (U.S. Air Force photo by TSgt Erica J. Knight/released)
