These days, the USAF is a social club 'led' by a bunch of sissified pantywaist Generals. Close Air Support has never been "cool" enough and besides it might conflict with Happy Hour at the 'O' Club.
(Before you flame - I'm an AF Vet, and not at all proud of what has happened to the AF.)
Actually, O Clubs have long since become All hands Clubs (more PC). Os now go into town to a bar that caters to them.
