Manpower. Americans all. Born in Rumania, George Sackwar is doing what he can to shoot up the Axis - not with a gun but with the radial drill on which he makes parts for medium tanks. One of many hundreds of loyal, foreign-born Americans who work in this large Midwest tank plant, Sackwar is proud of his role in the war. "Maybe I'm too old to fight," he says, "but I'm giving our soldiers something to fight with." Pressed Steel Can Company, Chicago, Illinois
