Your O-5 may have committed this crime while on active duty, I presume, which makes it logical that he could be called back for court martial. I still wonder about a retiree who is already released from ready reserve and out for say, two decades (y’know, just asking for a friend). Your excerpt from the code (thanks, btw), as I read it, does say a Regular Army officer, retired, can be recalled to active duty to be punished for calling some doofuses doofuses. If they don’t go after Kurt Schlichter, though, they are not likely to go after anybody. If they do take on the Vodkapundit, they’ll surely have their hands full. Love to see his column almost certain to come about just this issue.
After conviction and judgement he lost at the Court of Military Appeals. The real issue became retirement pay O-5 vs O-3 so the ambulance chaser could get a bugger cut.
