I remember the era, in fact I enlisted the following year I remember many women that were not in medical, I simply enlisted with no requests for specific duty, they could put me wherever they wanted to, is that what you tried, because by 1970 the military was years past the days when they limited female enlistments to 2%.
All I know is that’s what the recruiter said. Maybe he was old school. Who knows. There’s a lot of water under the bridge since then.
