Indeed. Heavy machine guns are not humane against personnel. They are only intended to be used against material.
So always aim at the belt buckle, buttons, helmet, etc.
You’re job is to kill a guy. What’s humane about that? One of these things hits him, he’s dead real quick.
What’s humane got to do with it? Close quarter getting multiple m-16 rounds tearing you up and dying, or one long-range round taking you out. You can say both aren’t in the ‘humane’ category. You’re killing someone for crying out loud. It’s not torture or cruel and unusual punishment. You’re not dropping a huge vacuum bomb on them and having them hemmorhage their lungs out. It’s a distance thing.
