I saw it immediately as more of a self-discipline/meditation group rather than an actual combat training system. "Fire, shouting, and spears"? In a part of the world where you can't swing a dead cat without striking an AK-47 or RPG-7 and everybody goes "fwap fwap fwap fwap" at the slightest perceived insult or religious heresy? Yeah, that'll go well for them...
