You'll need the same basic skills whether you are trying to control a violent offender by utilizing a headbutt, evading a knife-counter-knife situation, or denying a criminal trying to obtain your firearm. A low center of gravity, balance, and body mechanics are just a few gross motor skills that will enhance your performance in all three situations. Work on developing these abilities to improve your overall response to offender attacks.
The Headbutt
The headbutt is a perfect example of a technique that requires a seamless transition of moves. To achieve the optimum position you must apply basic motor skills correctly. It can be used when you need to stop an offender's resistance and regain control of the situation. The goal is to smash the top of your head (not your forehead) into the face of the offender between the eyebrows and the chin with such force that it will momentarily stun the person and give the advantage back to you.
To properly perform the technique you first need to bend your knees. Then grab and pull down on the back of the opponent's neck in a violent motion while simultaneously extending your legs and propelling your head into the offender's face. While executing the headbutt, keep your tongue in, teeth clenched, shrug your shoulders up to your ears, and keep your elbows in. This will create a solid mass similar to the head of a torpedo while protecting you against injury.
For maximum damage, precede the headbutt with a knee to the groin. Whether you connect or not, the offender's human response mechanism will buckle or bend the body to naturally protect his vital area and cause his head to shoot forward exactly at the time you pull on his neck and launch your body upward, creating a major collision between his face and the top of your head.
