i would think that when you join the army, no matter where you are, you are busy doing what the army wants, where they want it, and when. wont leave much time for training or finding different areas to train at. if u want to "travel the world and stuff" its cheaper than you might think so no need to join into the "see the world" hype that the armed forces uses to recuit. If you want to see the world and train. go for it- several fighters travel around living out of thier vans traveling from one place to the other learning as much as they can.
