I have been trying to get back but no one wants an E-8. If I was E-5 I'd be over there again yesterday. The best bet is to find a unit who is about to rotate in, and see if you can swap positions with an equivalent rank and MOS there. The military has allowed troops to change duty stations as long as all parties agree.
I for one don't know why they stopped me after two tours. I was already there, there was no training, travel, or other costs involved that occur when replacing me. And plenty of us wanted to stay!
