These techniques are not only the most interesting in Taekwon Do but also the most advanced. They are, in every sense, for practical self-defense. These techniques are the logical application of various motions acquired from patterns, sparring, and fundamental movements to be used against a sudden attack by an armed or unarmed opponent.

The defender must know how to make use of his opponent's momentum and force while utilizing his or her dynamic and reflexive actions against a momentarily undefended target. All Taekwon-Do techniques are to be used only for self-defence. They are not to be used for aggression, except in cases of grave immediate danger for the practitioner or someone he or she must protect. Any other use would be considered assault.

Because of safety concerns, the rules of competition prohibit the use of techniques using the elbow, knee, or head as well as attacks below the belt. However, these additional techniques may be needed in special circumstances, for example when defending against armed opponents, or from a sitting or prone position. Therefore, these techniques are practiced in training. Once mastered, the techniques will be available for use in genuinely dangerous situations.

Taekwon-Do offers realistic, practical, and efficient techniques for good self-defence.
