Well I think it's more of the fact that it seems like just about ANYONE can be sent on the draft. And depending on the situation, sometimes training just isn't going to cut it.

Children or people who are disabled in someway are still not going to be as effective in a war against people who are even giving the Malnosso trouble. War is no place for amateurs either. It's better to have a non-combatant than someone who has barely trained with a gun, for example. That's just asking for accidental friendly fire.
