But it's not.
According to you an officer must follow his orders no matter who gives them or what they are.
Or are there some cases when an officer can disobey orders?
Uh, no, little fella. I didn't say that. It's difficult to take you seriously after such an idiotic comment.
Or are there some cases when an officer can disobey orders?
Sure. When the orders are unlawful. But those deployment orders are not unlawful.
Not only can, but must. If the orders are illegal. Now clearly if the orders are to commit and illegal act, they are illegal. Orders given without authority to do so, that's a bit more of a gray area, but it would seem that such orders aren't even really orders, they just have the form of orders.
I suspect the Major will meet his movement orders and let the lawyers figure it all out. But we shall see, and soon, since he's supposed to report to Homestead AFB tommorrow.
