Call me biased, but anyone looking to join the military for the purpose of getting an endorsement on 737/A330 is going in with the wrong attitude. Particularly since your choice of aircraft type (post-Wings) is not really in your hands.
Be a shame to spend all that time dreaming about your airline salary prospects to find yourself posted to King Airs (no offence to the 32SQN folks)
