The question here is what is considered a lawful order.
As we keep trying to tell you, this is actually a complex topic, there is no simple clear answer.
So soldiers ordered to kill innocent civilians is not an unlawful order according to you?
And this is a perfect example, in what context? Here, let me give an actual answer from my own experience.
My first duties in the military involved guarding a Naval Weapons Station. And at that time, we still had nuclear warheads on the base. And when you are talking about something like nukes, a hell of a lot of the "normal rules" go right out the freaking window.
If an order was given to just randomly start shooting people, oh hell no, that is unquestionably an illegal order. And I should actually with others relieve that individual of their position and restrain them.
But if some terrorists managed to get that nuke and load it onto a bus full of nuns and orphans? Well, that just freaking sucks. But when that order is given, I light the bus up. Even if in doing so I know I am going to kill every nun and orphan on the bus. Because absolutely
nothing stands in the way of preventing somebody from getting their hands on a nuke.
To give an idea how deadly serious the military takes something like this, all the way back in 1984 I was trained on the textbook definition of "Deadly Force", as well as the 6 justifications for the use of deadly force. And even though I have not had to actually operate under those conditions since 1987,
I still can recite them verbatim from memory.
Deadly force is that force which a person knows, or should reasonable know causes substantial risk of death or serious bodily harm. It is only used in cases of extreme necessity, when all lesser means have failed or can not be reasonably employed.
Now that may have had some minor changes in the past 41 years, but I can guarantee it is almost word for word what is still used to this day.
And then the six justifications.
1. Self defense
2. In defense of government property vital to national security
3. In defense of government property not vital to national security, but inherently dangerous to others
4. Prevent serious offenses against others
5. Apprehension and escape
6. Lawful order
Where you keep failing over and over again is that you can simply not comprehend that there is not clear "right or wrong" answer. You want a simple answer to a complex question, and are giving absolutely no context. But to answer this one, actually it is quite clear. Being ordered to kill innocent civilians
may indeed be a lawful order, depending on the context.
Fun fact, in 1988 I was assigned to an administration unit. And one of the tasks that was given to me was to rewrite the "Security SOP" for the base I was on. Now this was actually a book that was about 120 pages long, and one of the things I noticed right away was that it was incorrect in some places, and omitted some things in others. Now of course I no longer had the Standard Operating Procedures from my first duty station, but I had read it so damned many times that while rewriting the SOP for this camp I made a lot of changes and corrections. And even my Lieutenant was surprised, as when he gave me that task he had no idea that I had spent almost 4 years directly operating under such orders as my primary duty.
That is actually the kind of "attention to detail" that the military expects of those that serve in it. To be able to digest and understand a 100 page document, then apply it to their day to day tasks.
