That's the war is supposed to be. That's what makes war different from a quilting bee. If they can't take a little death and destruction now and then, maybe they need some sense beaten into them. That's how we handled cowards in the old days, and it always worked just fine. Well I don't want to grow old and die, but that won't stop it from happening.
Soldiers die, that's their job.
Let them do it. There's no need for war anymore. Because war is fun, damn it, and it's what we military commanders like to do. If they don't like it, then that's just too bloody bad. Well they'd probably like just about as much as I like not being able to direct large scale battles.
