he made a choice and went with it, and got away with not fighting.
i think he should either leave the army honourable discharge, or continue to serve and go fight.
punishment? dont you think his squaddies and most of the rest of the army will give him punihsment enough? well, the ones that make it back from iraq any how.
edit: then again, maybe he needs to be made an example of to limit any troops who support him, or are simply cowards, from attempting the same stunt.
