I had the pleasure to serve under two, a CWO-2 and A CWO-4. Two of the finest men I have met!
Don...I think they revived the WO1 for a short period of time specifically for the first batch of PA's. I believe it was for only one year in 1971. I think there were only 10-12 individuals in that AFSC the first few years. They did that because the PA's were writing patient orders and some of the nurses had problems taking orders from noncoms. Soon thereafter the AF required a BA/BS to get into the program and were commissioned as 2nd Lt's.
