Manpower. Americans all. Checo Blanco comes from a long line of Americans, some of whom probably resented those "immigrants" who came over here on the Mayflower. An Apache Indian from the Mescalaro Reservation in Arizona, Blanco is fighting to protect the land of his forefathers from encroachment by the Axis wreckers. He's a skilled machine operator who is processing parts for Uncle Sam's medium tanks in a huge Midwest plant. Pressed Steel Can Company, Chicago, Illinois
