Dirty Bombs - Bombs laced with radioactive material are forbidden under international law, though most countries wouldn't bother with them anyway. The point of a dirty bomb is to irradiate an area and make it uninhabitable -- which means that the "winner" of the war can't go there either. That aside, the amount of radioactive material necessary to make a dirty bomb effective could just as easily be used to build a full-on nuclear bomb.
And that's where you're wrong!
A dead soldier is left there for later pick up.
A wounded soldier imediatly takes 1-2 of his buddies to carry him to safety, wham 3 soldiers less with one bullet.
Remember: There are many kinds of wounded but only one kind of dead.
