"Collateral Damage" is another beauty.

It means, "Oops! Well, we killed a few innocent bystanders. Well, okay, maybe more than a few..."

This can happen even with the good guys, but that's just something you have to accept, because bad things happen in war. Hey, you gotta break a few eggs to make an omelet, right? (Didn't Kruschev say that? Oops! More collateral damage. Well...shit!)
