A Soldier is responsible for every round they fire. Yes, suppressive fire is a thing, and it has nothing to do with what you're talking about.
You don't randomly "suppressive fire" on things you can't identify.
You don't randomly shoot at things someone "orders" you to shoot.
You don't get to say "oh but LT dumbfuck told me to shoot that civilian" when you shoot a non combatant. In fact, by law you MUST refuse that order as it violates the LOAC. Go google that because I know you don't know what it means.
You are responsible for every round you fire. There are plenty of former Soldiers in prison for not believing that.
That's ludicrous and exactly what I'm pointing out as strawman. I will not repeat myself. I especially did not mention soldiers are not responsible for their rounds.
It simply isn't true. As a Soldier, you are responsible for every round you fire.
