The Invisible enemy

During tours of duty in Nevada, enlisted men and women were repeatedly and unknowingly exposed to lethal radiation at the world's largest nuclear test site. But because exercises were “top-secret,” the U.S. government continues to conceal official records of their ever having served at the location. Now cancer-stricken and ineligible for benefits because of their classified designation, veterans are mobilizing to prove they served and to secure basic healthcare for themselves and their families.
