All of them assume you are a nobody. The streets are full of ex military, ex police, ex mercenaries, ex private security, ex burglars, ex assassins, gangsters, robbers etc. that's never discussed nor stressed in these schools. They just have a program and a commission or salary. You are not going to understand when a person born in Afghanistan is trained to rupture your pressure points while they are still elementary school kids. Same goes for other parts of the world. You trying to box or kick or wrestle and get dissected by real killers. Not point fighting styles. Real machete, meat cleaver, chain and icepick MF'ers.
