You only have to follow lawful orders, for instance you would disobey an order to shoot a prisoner or an unarmed civilian.At what point in the military were you told which orders you could obey or disobey? Those coming from a sergeant? Lieutenant? All the way up to colonel? One of my best friends is a colonel in the Marines. I've never gotten the sense from him that nuanced decision making was something that officers valued or even tolerated from their subordinates.
