US law in this area is largely illusory. It makes reference to "lawful orders", but provides little guidance on what would constitute an "unlawful order". Getting it wrong means prison, and getting it right can still mean prison -- the last case I heard about, the military court basically said "the order is lawful unless you are told otherwise by a superior officer", making the entire question moot.
