What research and development unit allegedly involved ex-soldier Yasuji Kaneko?
Unit 731 Unit 731 (Japanese: 731部隊 , Hepburn: Nana-san-ichi Butai ) 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) of World War II. It was responsible for some of the most notorious war crimes carried out by Japan. Unit 731 was based at the Pingfang district of Harbin, the largest city in the Japanese puppet state of Manchukuo (now Northeast China).
2/1st North Australia Observer Unit The 2/1st North Australia Observer Unit (2/1 NAOU) was an Australian Army reconnaissance unit of World War II. Formed in early 1942 in the Northern Territory, the unit was a light horse mounted unit that was tasked with providing early warning of Japanese activity in northern Australia at a time when an invasion of the country was expected. As the threat of Japanese invasion dissipated the unit's operations were curtailed in 1943 and it was eventually disbanded in the early months of 1945. The unit is considered to be a predecessor of several reconnaissance units that currently exist within the Australian Army.
