question about pcs orders?

Unfortunately RobbieJ is correct here (sorry Gman). Since your husband does not officially have a retirement date (he can't drop his papers until he is a year out), they can force him to extend his current enlistment to accept the PCS. If not, he remains in place. They CANNOT force him to reenlist. Also, I don't know if things have changed in the last three years, but the army had a thing called "indefinite re-enlistment", so this may have an affect too. I found out the hard way that just because you hit 20, you don't necessarily automatically retire. I had to threaten a congressional to get out and know of a couple of army buddies who had to do the same thing. It is more likely to happen if your husband is in a critical MOS.

However, back to the question at hand, your husband needs sufficient retainability in order to PCS. Put another way, if they let him PCS with just the time he has, then someone would have to PCS to replace him when he retires, which will cost the army time and money in having to pay for a PCS at a time they did not intend to. It all comes down to dollars and fairness. On the bright side, he extends 8 months, PCS to Riley and soon as he is a year out from retirement, put in his papers. As long as he has retirement papers with a firm retirment date, he won't enter the extension period.

When you PCS to a new duty station, you are projected to be there a particular amount of time. Usually, it's 3 years, state side, I believe. So, if he will not be at that location for the projected time, they will request an extension for enlistment. Just like they're doing, now. If your husband doesn't want to extend for the little time needed, I don't believe he has to. I think they'll just leave you where you are. However, in that amount of time, it is enough time to go to Korea. So, it can backfire and he may be away from home for 12 months as opposed to spending an extra few months with his family.

No, his 1SG is trying to BS him into reenlisting. If you don't have enough time to fulfill his PCS orders, which is BS, then they can't move you. My personal experience with the USAF was that you needed a minimum of 12 months to PCS. Sounds like the 1SG is being a dick and trying to make himself look good.
