The 267-page dossier reveals personnel records for 100 technicians behind some of history's most horrific human experiments.
Discovered in Japan's National Archives, the files expose 'excellent' performance ratings given to researchers who conducted bacterial warfare tests in Harbin. Over half worked directly under Unit 731 – an army unit that turned living prisoners into test subjects during Japan's wartime occupation.
