JOINT BASE BALAD, Iraq -- Airmen of the 732nd Expeditionary Civil Engineer Squadron use a 1500 gallon water truck to soften the earth for a sheep's foot roller, as it compacts the soil for a new container repair yard Nov. 2, 2009. By using containers repaired here instead of purchasing new ones, the projected savings total more than $100 million as military assets withdraw from Iraq.
