The social experiments caught my attention. Is this a literal experiment or were you just talking about the military having to become politically correct?
The Army has a history of being involved in “social experiments” mostly at the whim of politicians and academics, but some arose interally - attractive because of having a controlled environment, and controlled population who couldn’t say no. Beginning with integration of African Americans in support positions, then fully integrated combat units during WWII, then women in support positions, then “don’t ask don’t tell”, now open homosexuals and women in combat roles. Also smaller stuff that would have been unacceptable in the general society at the time- things like socialized medicine, use of the media in conflict, use of psychological testing (ASVAB) and conditioning (brain washing), use of performance enhancing drugs (pilot use of stimulant drugs), radical leadership and organizational models, suicide prevention, crime prevention, zero-tolerance drug policies (even over the counter), elimination of sexual harassment (since Tailhook).
