I found from youtube this Finnish military close combat training video from 50s. Starts at 02:00 first there is stances, then falling, kicks, strikes, grappling and throws etc. What do you think? At least I found some similarities to karate and judo. Which is quite understandable, because humans are similar all over the world and same techniques works. I don't know has those guys heard of karate and judo, but if same techniques are "invented" and taught independently two opposite side of earth, then perhaps those techniques are useable. (Sorry, about the language, I am not going to translate it).
