Commando Krav Maga is by far the best self-defense techniques I have seen, and that includes the Marines, Army, British Royal Marines, and KGB. The techniques are easy to learn and effective. He covers everything from what to do when someone pokes you with a finger to how to handle an axe handle attack. I highly recommend Commando Krav Maga. I am not a CKM student and do not know Mr. Aizik but he obviously knows his stuff.
