Do you acknowledge that there are some orders which can only be given by the CIC?
If Lakin had ordered his underlings to go to Iran and fight the mullahs would you expect him to have to show some authority for being able to give that order? Or would his underlings just have to go invade Iran without question?
I'm not sure what the order in this case would be. Did Obama order troops into Afghanistan? Nope, that was Bush. Did Obama order Lakin TDY to the 101st Airborne? Nope, that was the Army. Did Obama order the 101st to deploy? Nope, that was the Army again. So what specific order are we talking about?
If Lakin had ordered his underlings to go to Iran and fight the mullahs would you expect him to have to show some authority for being able to give that order?
If Lakin order his subordinate to empty the trash can does he need to show some authority for that? At what point does an order have to be obeyed merely because it's an order from one's superior?
