Heavy objects were dropped onto bound victims to study crush injuries, subjects were locked up and deprived of food and water to learn how long humans could survive without them, and victims were allowed to drink only sea water, or were given injections of mismatched human or animal blood to study transfusions and the clotting process. The complex contained various factories. Another group was clothed in summer military uniform and shoes; three had masks and another three had no mask.
