Thanks very much for the replies everyone.
Artist, I am in the process of transferring out of the OTC having done my first year back to TA (perhaps it should now be Army Reserve), the course I'm hoping to get on is rather challenging but its something I've wanted to do for some time.
Yes I gathered the student room can be rather hit and miss, though the "100% UAS aircrew" comment did alarm me - hopefully its baseless. I just didn't want to burn any military flying bridges whereby someone with UAS experience would get selected over someone without it, this seems a bit daft given there are plenty of uni's not covered by UAS.
Thanks again.
