We had one of those once in the Air Force. Everyone was well drilled not to volunteer information, but the one captain did so anyway. He knew what he was talking about, and described how we were, in fact, following the specified procedures, but he knew that there were areas where the procedures could be improved. He volunteered a ton of information, and got a commondation for it.

Breaking the rules like that can be good, if you're squeeky clean and know your stuff thoroughly. (The boss will still wince while you're doing it.)
