Well, if you want to use the military as a stepping stone you may find you have more on your plate than you bargained for!
To become a pilot in the RAF you will need to stay on until you are 38 or have done 16 years service(I think that is right). Any chance of leaving early costs heavily.
As for a spot of Iraqi bombing it will take 3 years to train you and then the compulsary 2 years holding waiting for a squadron!, so you may be in for a bit of a wait.
You also may want to check up on your aircraft types before you go for selection in 3 years time as you quoted mainly US types!!!!(you will only see them flying at you)
Other than that, good luck with your exams...they will probably be the determining factor on your choice.
