I ran across this on YouTube, it's called Combat Ju-Jitsu and from what I could find it seems to be contested primarily in Russia, Eastern Europe, and Asia. It seems similar to Combat Sambo in many ways and looks like an interesting rule set for competition. I've always liked the combination of the gi in a striking environment. There were some self-defense demonstration portions that I cut out of the clip but a quick search on YouTube and you'll find it. Does anyone on here do this or know more
