What are the chances of me getting stationed where I want?

That all depends, on what job you get. In certain career fields if you are the top grad in your tech school, you get a base of preference. I am stationed at Kadena. On Okinawa, Japan. You are able to leave base and explore. If you are not married, and wouldn't mind holding out for a year, you can go to Korea and get a base of preference once you leave.
