Solid Snake is a master of stealth, a legendary soldier with years of experience, but are those skills transferable to the world of self-defence classes? Not unless you want to learn how to brutally murder people with your bare hands.
So yeah, Snake's methods of murder don't really transfer to the world of self-defence, but I sure as hell would love to get some more lessons from him.
— Like how to answer a codec call and not get spotted in a crowded room. — How to heal wounds by using a lit cigar. — How to be three feet away in plain sight of elite soldiers and not get spotted. — How to climb really, really big ladders.
All jokes aside: Solid Snake has so much to teach us. CQC is the best!
