Sorry to confuse you ops33, but my "W04Man" handle doesn't stand for W-4. It stands for Bush 2004, ie http://W-04.com. You are right, I retired in '83 and there were not very many warrant officers in the AF. I knew a couple in the late 50s/early 60s.
Thank you for your reply. Out of curiosity, what did you consider your best assignment?
