Larynx grab restraint

Again only if the threat is minimal. I did use this technique a
number of times, but only when the threat wasn't great. I
used to psyche my opponents out more than anything -it can
have a startling effect. This grab is especially effective when
the opponent has his back to the wall.
Grab the opponent by the throat, on the inside of the neck
muscles so that your fingers close around the back of his
larynx. Squeeze very hard and back the grab up with firm to
aggressive verbal commands. It often helps to grab the
opponent's arm with your left hand while you squeeze with
the right hand.
