@Dutchess_III since you were never in the military you have no point of reference for how things work. Even when I was in, we were taught to follow orders, but not to be stupid. Just because an officer gives you the order to commit a crime does not mean you are required to do so. The Uniform Code of Military Justice has three sections (articles 90, 91, and 92) about the crimes and punishments of disobeying lawful orders. If an officer gives you an order to do something and you don’t want to, don’t think it’s safe, don’t understand the importance, etc. that does not make it an unlawful order. However, if the officer gives you the order to commit murder, that is an order directing you to commit a crime. That is an unlawful order since it is an order to break the law. You have the right to refuse that order. Now, the officer can bring you up on charges of violating an order, and you might have to go to a court martial to defend yourself. But if the order was, say, to kill unarmed civilians and you refused you have a pretty solid defense. In fact, it is likely that unless the officer is unhinged (which does happen), they would not bring charges against you because they know they would have to defend those orders in this same court martial.
