Each of these are essential combat forms at the highest level of practice possible (grappling, boxing, bowcraft, knife fighting, and holds). Summarized in one line, the actual disciplines of training, not necessary.
Wrestling: “You’re going a bad way”. Now they have a psychotic break, otherwise they give you money.
Karate: “Martial arts is about self-defense”. Now you counter anyone, as long as they attack first, otherwise nobody fights, and we make money.
Sambo: “Everyone works together.” Now you can use marksmanship with firearms, unless they fire first, in which case it gets on the news.
Shyst: “I love your sarcasm.” Now you know shyst, too, and you’ll kill all my enemies, by virtue of them supporting their mother.
Kung Fu: “‘Rape’ is a power word.” Now you control other people, with your mind, and forward projection.
