I'll echo IBC's position on this one... Regardless of the situation, and notwithstanding Article 88, there's a certain professional decorum dictated by high-level positions, and I believe the General was in the wrong.
On a side note, HOW THE HELL did he think it was a good idea to even speak to an anti-military, counterculture ragsheet full of questionable, biased journalism like RS? Come on, General. Think, for f***'s sake.
Given that, if it's found that he didn't actually invoke POTUS in his criticism specifically, and by some small technicality he is spared the consequences of Article 88, I'd be well-pleased. His job, in its simplest description, is to kill people and break stuff, and I could give a damn what he says to a journalist, as long as he's doing a good job out in the sand.
But yeah - Let's not be disparaging the POTUS in public, General. Bad form.

Re: proper addressing of people... Mr. Obama is NOT one to talk. Not many noticed, but his arrogance and disdain for others was never more apparent than during the presidential debates when he continually and disdainfully referred to Senator McCain as "John"... over and over again. McCain took the high road throughout, and never once stooped to calling him "Barry". Not once.
Unfortunately, the damage was done. Although the balance of power and experience and service to our country clearly favored McCain, by virtue of that simple manipulative act, BO appeared "presidential", Senator McCain appeared the underling. Impressively devious, but unforgivable nonetheless.
