He *should* be able to enlist with a guaranteed AFSC, but may have to sit in delayed entry for a while waiting on the slot. As far as I know, the only way he could be an FE right off the street is to go the helo route. I am a fixed wing FE and was a retrainee. There have been some changes in the policies regarding qualifications for the FE career field, so maybe one of the helo guys here will chime in. As far as the other AFSCs go, they can be obtained right off the street, but I'll defer specifics to those that are in those jobs. Also, it's been a while since I've gone through the aircrew training process, so I may not be much more help, but feel free to PM with any other questions!
