Can I do anything to change my orders after reenlistment?

Always the first reaction to a misunderstanding with a recruiter or re-up NCO is " I got lied to". The retention NCO has nothing to gain by the re-enlistment option you re-up'ed for. Chance's are there was an error or something is misunderstood somewhere. Sounds like its all six in one hand, and half dozen in the other anyway. But you shouldn't automatically assume you were "lied to". That is just jumping to conclusions because of the perceptions and stereotypes associated with retention NCO's/recruiters. And, as you have already heard, you should hold yourself accountable for not reading your contract and asking questions before you signed.

Mine was easy. When it came time to reenlist, I extended 18 months in Korea.
Time to reup again, asked for another 18 months, it was denied. Asked for an exception to policy from DA, they granted it. Time to reup, I said no, offered me additional 18 months. Said I'd stay for COG 2yrs it turned into 2yrs 6 months. 9 1/2 yrs USArmy still a first termers. Gotta love it!

What I have been told because I have recently put in a re-enlistment package and I’m thinking about changing my orders after I already put the MCC codes for the orders I want is, if approved and you want orders changed from the orders you requested, you can contact the monitor and request a change. I don’t know how the army works with order changes but if you guys have something along those lines, try talking to the person that makes the orders

Direct answer is no

You reup at your own peril. Didn’t take me long to know that the army will screw you if it can. Trust no one!

file a lawsuit... deceptive contracts violate contract law

So, it’s maddening how RallyPoint resurrects these threads that are a year or two old, but it did remind me of my first experience with orders from Uncle Sam.

My recruiter talked up Europe big time - beer, girls, weekend off, etc. I was gonna sign up anyway, but Germany did sound pretty cool to a young 18 year old private. I finish up infantry school at Fort Benning and get my orders to Alaska. What? That’s pretty damn far from Germany. Now I’m a cocky little E1, but I know I’m right. I go find my drill sergeant and say, “Drill Sgt, there’s a problem with my orders.” Without even looking up, he drawls, “son, there’s no problem with your orders”. I’m like, “I’m supposed to go to Germany, I’m not going to Alaska.” He looks up at me and says, “oh, you’re going to Alaska”. And, ahah, I thought - ace card! “No, Drill Sgt, this has to be a mistake - I have guaranteed orders for overseas”, I said in a tone that just knew I was smarter than he.

He laughs and tells me that the Army considered Alaska overseas, so I should just go get on the bus.

Lol. As an aside, I had a blast in Alaska.

If its not in writing, it most likely won't happen is the issue. Recruiters and Re-enlistment NCO's have quota's, I know its been 40 years since my days working in the Brigade Re-enlistment Office, but I suspect things are pretty much the same. You don't meet the quota they give you, you lose your cushy position, end up in Hoenfelds in the middle of winter, instead of sipping hot coffee and playing cards with the other NCO's in my office.

Outside of failing a drug test? Probably not. But, I would always consider speaking with my Commanding Officer and openly discuss your concern and ask for His/her suggestions. If your CO is a truly good Officer, He/She will be Honest and candid and possibly guide you to resolution. Just be ready for news either way.

Talk to your "First Shirt" and see what comes out of that. They might be able to help you get an assignment you like better than the one you actually received. Chain of command can often times be your friend, as long as you are willing to listen and learn.
