This is just my opinion ....
He didn't go AWOL because he was on duty in a combat zone. I think AWOL is where you say F it and don't come back from leave. His crime is abandoning his post, at a forward operating position, in combat.

10. Punitive Articles

(9) does not afford all practicable relief and assistance to any troops, combatants, vessels, or aircraft of the armed forces belonging to the United States or their allies when engaged in battle;
shall be punished by death or such punishment as a court- martial may direct.
The wording is pretty clear, desertion is out, and the words, "before or in the presence," when literally interpreted, as they have been in the past,(stare decisis) will make a conviction of misbehavior difficult, but not impossible.
I think conviction will be for AWOL, if anything, which is a very serious offense, but I cannot mesh out desertion and misbehavior opens a whole can of worms, and endless appeals.
Lest we forget, this is not a declared war, so the death penalty is absolutely out of the question. Just another problem with these nasty undeclared wars we call police actions or regime change.
Time will tell, and the evidence that comes forth, will answer a slew of unanswered question, and may change a lot of minds, perhaps even mine.
