They do their work -- construction and electrical projects -- in some of the most dangerous spots in Baghdad. And those they serve couldn't be more grateful.
For the past eight months, a group of 155 soldiers from the Minnesota National Guard has been building "combat outposts" crucial to a new U.S. counterinsurgency process known as "clear and hold," in which soldiers station themselves in violence-prone areas rather than retreat at night to the safety of large bases.
The Minnesotans are from the Little Falls-based 851st Vertical Engineer Company.
Four of the major combat outposts that were staging areas for recent operations in Sadr City, a restive Baghdad neighborhood, were either built from the ground up or substantially improved by the 851st.
Thanks to these soldiers, the troops involved in building the "Sadr City Wall" now have a secure area where they can sleep, get a shower, eat a meal and even use the Internet.
There have been close calls.
Capt. Brian Winter, the unit's commander and a Maple Grove resident, said there has been an injury from a mortar attack. Their work has taken them places where private contractors cannot, or will not, go.
But given their duties -- essentially making life more comfortable for the other soldiers -- his soldiers find themselves amazingly well-protected, even as they wield their hammers with 80 pounds of combat gear on their backs.
