Unit 731

Level 1 – Surface Web

A covert biological and chemical warfare research unit of the Imperial Japanese Army during World War II. Unit 731 was responsible for some of the most horrifying war crimes, including vivisection and the testing of biological weapons on prisoners. Theories suggest that after the war, the U.S. granted immunity to Unit 731 scientists in exchange for their research, which might have been used to advance American biological warfare programs.
