 So, through the course entails mental character and physical discipline, so the Marines don't just become instructors, but they also become something more. The physical portion of the martial arts instructor course is all the different events that we put on, from the physical training exercises and the free sparring event. The mental aspect comes in with the tie-ins that we teach, which are just little hip-hop classes of different things that the Marines have to learn. The character aspect of that, they're able to push themselves past the point that they thought they could go past, and then not giving up on themselves and not giving up on their training throughout the entire course. The Marines start off kind of individuals, and then throughout the course they become a network and a family, and at the end of the course you couldn't tell the difference.
