>>Have you ever done it? Have you ever disobeyed, or refused to carry out, an order that you considered to be illegal? I have Captain, not the best of career moves, but right just the same.<<

Quit lying. A soldier not only does not obey an illegal order, he is REQUIRED not to. If you carry out an illegal order, THAT would not be the best of career moves because you will be charged no matter who gave the order. Nothing will happen to anyone who disobeyed an order they considered illegal as long as they can make a case for it (as opposed to trying to justify simple dereliction). But if you carry out an illegal order, you WILL be charged.
