Nearly 300 more Iowa National Guard troops are being activated for federal duty. The Iowa National Guard says soldiers from the first squadron of the 113th Calvary Regiment are being mobilized as part of “Operation Enduring Freedom” and the war on terrorism. A news release on the call up says the 296 officers and soldiers from Sioux City and Boone will serve as a peace-keeping force in Kosovo. The soldiers are scheduled to report to duty in early October, and will be on duty for up to one year. Portions of the units have not been called up since World War Two.
