Rear Naked Choke & Multiple Assailants

Normally, you don't think of grappling as a way of dealing with multiple assailants. The following video, however, demonstrates the rear naked choke as a means of controlling one attacker and using his body as a shield to fend off the others

Notice the importance of taking away your opponent's balance. In my opinion, you can get better control by taking his equilibrium than with pain compliance techniques, because the fear of falling is an instinct everyone has from birth.
