They are not related. Realize that systems said to be used by this or that military force are, by and large, not. Hand to hand combat is barely taught in the military. Most of the military training deals with situations that a soldier will be in. Automatic weapons, handguns, bladed weapons, and lastly H2H. I have a lot of relatives and friends that are either active duty or have served in the IDF. SOme of them have taken KM. They say it bears some resemblance, but no more than that.
