Youngsters are inclined to think they are invulnerable. That it's always someone else that gets killed, they won't. If one actually thought the odds of them getting killed were fairly high, I doubt there would be many volunteers. Remember the saying, young, dumb, and full of cum. The ones volunteering are the ones with the football mentality, you know, the coach jacks them up and they are running on pure adrenaline, the same shit applies in the military. The enemy is evil so therefore if you kill one it isn't the same as killing a human being. I know, I've been there! When I was called to duty, there was the draft, or else I'd never have gone!
