The Pentagon has alerted an Iowa Army National Guard unit it may be called for federal active duty. Guard spokesman Colonel Robert King says the 1034th Quartermaster Company is based at Camp Dodge and could be sent to serve for up to two years. This is part of the war on terrorism, Operation Enduring Freedom. The company has about 90 members, most of whom are based in the Des Moines area. The combat support supply company is trained and equipped to distribute a broad range of supplies and materials in a theater of operations. Colonel King says two other Iowa-based Guard units are on stand-by, but are not on alert.The quartermaster unit was mobilized in 1990 and deployed to the Persian Gulf as part of Operation Desert Storm. King says the company may go to active duty late this month. The other units that have been notified for possible alert are: the 2133rd Transportation Company out of Centerville and Muscatine and the 186th Military Police Company of Camp Dodge.
