So every soldier and sailor should question every order from their officer or their NCO for any reason they care to name? That isn't an army, that's a mob. Perhaps that's what you want?
I did it for eleven years, it really isn't that hard to do.
I'll start out with the basics, in boot camp a drill instructor gave an order that would have marched my platoon into a wall, were we supposed to march into the wall?
Of course not, it was a lesson in questioning orders, there are always orders that MUST be questioned as well as those that CANNOT be, what makes The American armed forces different from all other nations is that we are trained to think and act on our own even if that means disobeying orders especially illegal ones.
Quite honestly it is why we are feared around the world, there is a certain unpredictability to Americans that no other country has.
What is pretty sad is that you would strip that away from anyone that serves for the sake of Obama.
