No free gas :-)
Actually, the needs were taken care of quite satisfactorily. They gave you all your clothes and they laundered them free. Lodgings were sort for communal, for the lower ranks, At Randolph AFB I slept in a room with about 100 other guys. As I remember the food at permanent installations was pretty good . Medical care was good and totally free. What more could one want?
And, if one had visions of actually being a Bad Ass M-16 Toter all one had to do was volunteer.... and, of course pass some fairly rigorous physical and mental tests :-)
