(Army) What do I do if I fall on orders to PCS overseas in May but I ETS in Nov?

Asking my fellow army soldiers. I fell on orders to go overseas to Germany. My ASK says I should be reporting on May 10 2011. I ETS Nov 29th 2011. I know of the DEC statement, but my NCO keeps saying things that make no sense. Not trying to question a E7, he say’s I just go to the levi briefing and let them know I’m ETS’ing and they should delete my orders. At first he was saying do nothing at all. From what I know, If you don’t attempt to go, they hit you with a automatic DEC statement, which your chain of command has to sign, and this would cause problems, so doing nothing is obviously wrong. And I know that if you go to the levi briefing, they cut you orders, so I don’t think that’s the right way to do it too. I need help, because I’m on rear-d, and my brigade is deployed, so I can’t talk to my brigade Career Advisor.

PS: Extra info-considered mid career soldier, already re-enlisted once before. I know about the regs on that, but the problem is do I go in to the in and out processing building to try and get help? Or do I try to wait till my unit gets back to try and seek the career advisor really fast because theres only 2 months from march to may.
