CHICAGO (AP) – The Illinois National Guard is set to deploy about 400 soldiers to Afghanistan in what officials say is the largest mobilization of Guardsmen and women from the state in nearly a decade.

The Chicago Tribune reports that members of the 178th Infantry Regiment that’s headquartered on Chicago’s South Side and has companies from as far away as the Peoria area will start leaving this weekend to start a yearlong deployment to Afghanistan in support of “Operation Freedom’s Sentinel.”
