Are you arguing that boys are intrinsically badly suited to a highly regulated environment that expects them to do exactly as they are told as soon as they are told? You should tell the army.
why do you think the armies around the world have to threaten recruits with corporal punishment, prison, and even execution when they don't follow orders?
Don't forget the constant drill-and-ceremony, both in training and once stationed to a permanent post.
For those who don't "habla", drill-and-ceremony (D&C) is the "attention, left face, forward march" stuff that fills a good portion of footage about military life, not to mention certain films such as Full Metal Jacket.
Oh, and don't forget the role played by PT (Physical Training) in producing human drone-killers.
