IMO, the creation of an all-volunteer force in 1974(?) terminated the endless flow of manpower through induction. Consequently, it became necessary to initiate a host of unprecedented measures to maintain end strength. The most disconcerting measure initiated during the latter stages of my career was the introduction of the Maternity uniform.
Dittos to that. I retired from the AF in '75 and couldn't believe my eyes when I visited the base several years later and saw a major wearing a maternity uniform.
