After completion , the FOB had space for 4 , 000 soldiers , and was occupied by 3rd Brigade Combat Team , 3rd Infantry Division . After the completion of the FOB , 411th Engineer Brigade soldiers commenced construction on other facilities throughout Camp Liberty for other incoming Army units . At the same time , other units in the brigade were responsible for route clearance in the areas of Logistics Support Area Anaconda along routes used for military supply as well as civilian traffic .

During this deployment , the brigade completed over 200 projects on every major Forward Operating Base in the country , and three major projects supporting the Iraq War troop surge of 2007 . It completed over 400 , 000 kilometers of route clearance and blast hole repair using over 2 , 800 pieces of major equipment .
