Can you explain how this is relevant to this particular case? I know you have your suspicions and all, but...how does this extemporizing relate to the facts of this case?
Contextualize not extemporize. If as a member of the military you decide to engage in open political activity in uniform don't go looking for sympathy when the results hit you. In the Army we call it "doing whatever your rank will allow".
A master sergeant is pretty senior he knew what he was doing.
