BWL... good explanation. But, ya left out one point. It's true that soldiers should be wounded and not killed (fuckin strange to say such a terrible thing) but ya also want a soldier wounded rather than killed because it takes two + soldiers to care for a wounded soldier, thus taxing the resources of an enemy.

Like I said... all of that sounds absolutely terrible... but it's the way it is. Hopefully, someday, we can have no need to discuss any of it.
