The first of what may be many Iowa National Guard units has been ordered to federal duty, after being alerted earlier this week that they may be called to serve in the anti-terrorism effort called Operation Enduring Freedom. Guard spokesman Colonel Robert King says the activation came faster than expected.Colonel King says the 1034th Quartermaster Company is based at Camp Dodge and is being sent to serve for one year initially, a tour that could be extended for a second year. The company has between 90 and one-hundred 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. King says the unit will assemble later this month to undergo processing and briefing.King could not say where the unit will be sent, but confirms this same unit was put on federal duty in 1990.King says two other Iowa-based Guard units are on stand-by, but are not on alert. They are: the 2133rd Transportation Company out of Centerville and Muscatine and the 186th Military Police Company of Camp Dodge.
