Air Force as a pilot.
Main reason is that, with my brother being a huge aviation nerd, I learnt from him, his books, his plane simulators, his TV documentaries (everything from "boring" yet highly factual videos to more interesting stuff like Air Crash Investigation) a significant amount of what it is like to fly a plane and I'd love to be a part of that if I was being conscripted.
It also helps that one of my cousins is a qualified Air Force pilot in the Australian Army.
