I fail to see your point. I assume you feel that since the soldier is not physically inconvenienced or in personal danger, that he is more likely to make inappropriate kill decisions. In my opinion, exhaustion and fear are the enemies of good decision making. Your guy with the can of coke doesn't fire blindly because he's terrified. He doesn't fire on his own men because he's too tired to see they're friendly. Whether he "gets off" on firing on random targets, is a problem with the man, not the technology. Such a man would be a menace anywhere he was, even without the can of coke.
