So would "no ranks" or making them enlist first weed out the shit bags, or would they just be in the system longer before someone pulled their card?
I think ranks are an important part of the military. Is there a place in the military for No ranks? I could see certain areas that one might be able to make the case for that, but you would still have a person in charge and a hierarchy of authority.
Maybe being in the que longer would weed out a few, but there is always a few who manage to slip through the cracks, like Teufel's first Platoon Sergeant.
What are your concerns for requiring everyone to be enlisted first?
