The term "mutiny" is generally a Navy term, but in the Marine Corp which is under the Navy as the Navys Amphibious assault group, its a valid term used. May surprise you that Marines use terms like the Navy at times, such as responded to orders with "Aye Sir", or "Aye Aye Sir". Also used in the Coast guard I;m sure.
Its not really used in the Air Force or Army, but the bottom line is, they have a term that is the carbon copy definition of Mutiny. Every service has what everyone knows as the "Chain of Command", thats is universal, and also universal is they are all covered under the Uniform Code of Military Justice, and not by civilain/domestic courts. When you are in the Armed Forces of the United States your legal options are not the same as a civilian. Neither are your Constitutional rights the same. Your rights are dramatically changed the moment you have taken the Oath, and are in the armed forces. Also dramatically changed is your Duty to the country you have agreed to literally in blood.
Like I said, lets see how the news tells this story tonight, if it even makes the news.
