They will follow all initial orders as no order will be a direct order to murder. Few have the guts to disobey senior officers and want to keep their job as any of us. Many are minorities or AA that would follow Zero to Hell. Very, very few would question initial orders, and not enough would to matter. The orders will be carried out. Those under about 26 years old aren’t mature enough to know what a lawful order is. They’ll do as they are told.
I spent a multi-service career as a young NCO and as an officer. I never had any doubt about any of the troops, officers, or senior NCOs I served with other than a few colonels and a number of generals who were all political animals. Those types could have issued any unlawful order they wanted to but they would not have been obeyed.
I am still in contact with a lot of younger troops and I’ll tell you that they are mature enough and they, ONCE AGAIN, are not robots who will snap to, heil der Fuehrer and begin firing. We trust them to carry the load in places like AF and they meet and exceed the expectations.
