I actually like the sound of that place.
It's got military precision. A simple system of promotion and punishment. Basically, lots of order. And it is effective.
Notice how there is no mention of anyone being beaten or raped, or the guards carrying guns, or anyone being petty and evil. Sounds a lot better than most boarding schools.
All you've got to worry about there is following the rules, which anyone with half a brain and a little self-discipline can do. Whereas at every school the world over you've not only got to worry about the rules, but also the other kids taking a disliking to you, the teachers being petty, activities and study which you don't like or want to do.
Basically, it seems like a Buddhist retreat with guards.
If they taught some useful skills (unarmed combat, mechanics, carpentry, boxing, armed combat, politics etc) and allowed more parental visits, I'd send my hypothetical kid there.
