"Unit 731" was a Japanese Army
based in Manchuria during W.W.II.
It began to perform medical experiments on
human prisoners soon after it's arrival from Japan.
Most centered on the effort to find a way to spread anthrax.
Huge rat farms were constructed to provide rats for experiments.
Japan was hoping to release plague-carrying rats
into China to kill as many people as possible.
They also did experiments w/ Anthrax
and other biological weapons.
They conducted frost-bite experiments on U.S. POWs.
Manchuria is very cold in the winter, and the
Japanese were suffering many frost-bite casualties.
Unit 731 took U.S. POWs out into the cold air, forced them to strip
naked and then doused them w/ water to quicken the loss of heat.
Observations were carefully noted.
After the war U.S. General Douglas MacArthur recommended that
the Japanese doctors in the unit not be tried as war criminals.
He wanted them to turn over the bio weapon information
to America so it could be used to make bio
weapons for the expected war w/ the Soviets.
This was done and the information was used
to develop several 'vaccines' against anthrax.
One is considered by many to be the cause of Gulf War Syndrome.
To this day the doctors have never been tried for war crimes.
Several make a living by giving lectures to medical students in Japan.
Some have been barred from entry into the U.S. because the govt.
doesn't want them to come here and spark media attention that
could disrupt the govt.'s. anti-POW/MIA media campaign.
