Are droves of young men really being driven into the ranks of the army in frenzies of desire? I somehow doubt it.
I am pretty sure the military is doing whatever they can do to market to that remaining 25%.
Beautiful women doing this I am sure is rather effective too. I would have considered the military far more when I was young if my image of the military was not that of the movie Platoon. A large group of young men getting yelled at by older men in between running.
