Where can I be stationed as a 88m? Can I choose where I want to go?

When it's time for you to reenlist you can choose where you go next. Your first assignment is where the Army needs you when they need you

As a AIT first term Soldier you have really no say where you go. They just send you where they need you.

Pretty much any post that has motor vehicles, as for choosing where you go? You will get a wish list and HRC may or may not give you what you want, be the best in your class and your chances are better of getting what you want, good luck!!
