What kind of martial art would teach people to break other people neck very easy like we see in the movies?

Question

the type of "neck breaking" arnold schwarzenegger would do in one of his commando movies ??

Answer 1

If you learned kata and was taught how to extract applications from them, you would find quite a few neck-breaks.

Answer 2

Muay Thai, Tang Sou Dou (spelt something like that), Judo

Answer 3

I don't know how many would actually teach it to anyone, but Okinawin and Japanese karate, kung fu, almost any style will have moves that could be used for it.

Whether they would actually teach it is another story.

Answer 4

Brazilian Jiu Jitsu
