I agree Jiu Jitsu and variations is likely the ultimate single combat fighting style, but the problem with real world fighting is it's never single combat... You can crush and maim your first assailant until he's a shivering blob of broken bones, but it doesn't matter if his buddy drives an icepick through the back of your head.

Of course, my Kung Fu is weak and I bow at your wisdom. It's possible a good fighter can break bones just the same in a vertical position a-la The Protector.



I've read the US military has this very sentiment in mind when planning future ground support drones.
