I've watched a video of Systema on youtube, I'm wondering, is it all a magic act or does it actually work? They seem to just hit someone, not even hard, and they fall to the floor like a corpse, it's quite amazing really.
This is the video http://youtube.com/watch?v=O7_dzu4TQDs&feature=RecentlyWatched&page=1&t=t&f=b
Watch at 0:45 seconds in untill 0:53 seconds in, that is one move that particularly caught my attention.
