do you think they're told to make those stupid noises in the video or are their punches just that fast?
one of my favorite 'testimonials':

I was a Sergeant in the U.S. Army for 8 years. I was privileged to some of the best hand-to-hand combat training the military had to offer. After leaving the ARMY, I studied Kali for 3 years I believed that I had taken my Martial Arts as far as they could go. Today I believe that Commander Coal Akida offers the finest training program in the world.
