What is the process taken to get out of an AD contract with a little over 2 years left and switching to NG, Reserves, or a general discharge?

This is correct you will be treated as in breach of the contract you signed. They are not going to do you any favors. Your rank will be frozen and for the 6-8 months it takes to liesurely process your paperwork you will be under a no favorable actions ban which they also tend to call a bar to re-enlistment. Leave requests very restricted, your restricted to barracks or post usually and eligible for every single work detail that comes across the 1SG desk. Additionally, in an Infantry unit your going to be continually picked on because your not going to be training with the other soldiers and they will treat you as voluntary dead wood. You will leave the service after this 6-8 month period very bitter at how they treated you on the way out.......nobody will care in the unit though.
