Im in korea, I have two years left in AUG but I Deros mid AUG, ETS is 08/08/10. Was wondering if it's possible re-up and reclass to 88M as soon as I can. Any chance of a bonus?

If you are an initial term Soldier (never reenlisted or minimal prior service) you'll be offered Option 3, Army Training Reenlistment Option and you'll more than likely be offered 88M. (This will occur while you're within you 24-month reenlistment window)

As for a bonus, you will not be receiving one (unless you are deployed to Iraq, Afghanistan or Kuwait) because you are not yet qualified in the MOS you are retraining to and you are you will no longer be serving as an 11B.
