KEESLER AIR FORCE BASE, Miss.-- Tech. Sgt. Robert Martin, 403rd Communications Flight network administrator, installs a router in the flight's new Network Training Work Center during the August Unit Training Assembly. The center is designed to simulate two linked networks set up at separate geographic locations. Having the work center up and running provides the Citizen Airman of the 403rd CF with a valuable training tool for sharpening their network skills. (U.S. Air Force Photo/Tech. Sgt. Ryan Labadens)
