Krav Maga as taught to Israeli soldiers might be some such animal. The scam with the same name where you get an instructor's certificate after a brief workshop which allows you to rip off the gullible is pure bullshido.

Agreed. Even the place where I trained briefly, which was run by a couple of former Israeli soldiers, was not on the level of instruction of some of the other martial arts dojos in the area. You can make a competent fighter with a few months of hard work, but it takes years to make a serious martial arts expert, so when it comes to military arts I tend to categorize the military instructors quite differently from the instructed.
