This video hosted by Kim Iversen from the Hill, contains an excellent debate. Do U.S. soldiers have a right to express dissenting opinions about their senior command's orders? Do they not have a 1st Amendment right, that trumps any command that can be handed down to them by the military, about expressing their opinions about military and other matters? (This is not about disobeying an order, it is about expressing a dissenting opinion.) Also, is the military obligated to follow its civilian leaders, even if it judges its orders to be unlawful?
