I agree completely with Jackonicko. Until the Services introduce a degree scheme that is worthwhile, and the government are determined that far too many school leavers should continue to university, the the military will have to either recruit more undergraduates/graduates or the calibre of recruits may drop. Although I am informed that there is no lack of volunteers for pilot.
As for Phil2005, apply to join a UAS, but be prepared to answer the difficult questions. Blow you own trumpet, but try not to sound too cocky. If you come across well at interview, there is no reason that you will not get invited to join.
Good luck
