Unit 731

Nobody does "detail oriented" like the Japanese.  In the post-war period, that's been a blessing for the world, as we've seen a flood of high quality goods come out of the Land of the Rising Sun.

During the war?  "Detail oriented" took on a much more menacing tone.  Like with Unit 731:

Unit 731 (Japanese: 731 部隊 Nana-san-ichi butai; simplified Chinese: 731部队) was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that undertook lethal human experimentation during the Second Sino-Japanese War (1937–1945) and World War II. It was responsible for some of the most notorious war crimes carried out by Japanese personnel.

10,000 people were used as human guinea pigs at "research laboratories" in China and Korea.  Men, women, and children were vivisected (dissected while alive) to see the effect of removing various organs.  Some had limbs frozen and then thawed so that the process of gangrene could be tracked with meticulous detail.

Some were used in ordnance testing, to see how new designs in grenades or flame throwers would effect the human body.  Some were used as biological test subjects, for plague, cholera, and anthrax.

The scientific results of these experiments were later used to kill 400,000 Chinese civilians.

But remember, on August 6 we in the United States are expected by our Moral Betters to hang our heads in shame for dropping the Bomb that ended the war and put this unit out of business.
