In either case, the prescribed punishment for remaining gone is court martial. And they can charge him with both if they feel like it.
Girlene’s point is what I’ve generally followed: packing up his possessions and shipping them home is an indication of intent.
Moreover, it appears that he waited until late and snuck off. That also goes to intent.
So, he SHOULD go to court-martial.
Since it will make Obama look silly for Bergdahl to go to court martial, then they’ll declare him a mental case and discharge him.
I wouldn’t be surprised if they have an Article 32, but no court martial. From what we know, it would seem a court martial would be recommended, but, like you indicated, it probably won’t happen.
That will set a very bad precedent.
