The only thing you can get guaranteed is that you will be sent to flight school. No guarantee of when. If you finish TBS, and PCola is backed up, you might go to a flying squadron to take out the trash, or you could go to IOC, since you're already in Quantico. Once your done with flight school, you will go to a fleet squadron, but for how long is a game day decision. As a Marine aviator, you will spend time away from flying squadrons. Like the previous post, if you're not down with that, the AF is the place for you.
