Truscott compares the training received in the military with these weapons way before you are ever allowed to fire it, and then only under expert supervision, with the situation in states like Arkansas, were it's legal for a child to possess an assault weapon with no training of any kind. 
Truscott compares the intensive training you get in the Army with one of these weapons long before you're ever allowed to fire it, and then only under the supervision of an expert marksman, with the situation in states like Arkansas, where it's legal for a 10-year-old to own a semiautomatic assault weapon without a moment of safety instruction, training in how to shoot it or adult supervision.
