There should just be a automated bot respond to 90% of threads with "it depends". as i put above, it depends and it does depend heavily on who teaches it. As i dont know Russian i dont know the context of this video. I believe the creator militarized his sports knowledge under defendu via some form of training or service with the U.K/western allies. Providing all the sources i got is accurate and all that stuff. I would say its unique enough to be called Israeli and be his system per say. Honestly krav maga is one of those milked to death things, im not too sure if there is a world wide organization of "proper" krav maga who maintains standards but its so fragmented and has a plethora of different teaching methods to its name you could have a very distinct training quality difference. Also a big point, you aren't getting what the ISDF gets and the police get a different one to them etc. Plus their standards take into account you being military fit anyway. Before this turns into a rant, thats all i have to type. I dont harbor a specific dislike for it, that's just the problems i see for it. Also some of the above might be known/obvious for some of you.
