Choke: A choke constricts the windpipe and restricts the flow of air in and out of the body. It is accompanied by acute discomfort, which usually results in the victim struggling violently.
Elbow strikes: An elbow is much less likely to be injured than a fist if it strikes something hard. Elbow strikes include hooking elbows, which follow a more or less horizontal or overhand curved path, thrusting elbows, which are driven directly to the rear or side, and rising elbows, which come up under an opponent’s chin.
Grappling: Any situation where the combatants are able to grab hold of one another. Most unarmed fights involve at least some grappling, though skilled fighters learn to use strikes as well as grappling moves when in close combat.
Kicks: Any strike with the foot or lower leg is a kick. A front kick comes directly out forwards; a roundhouse kick is a rotating kick normally thrown from the rear leg and impacts with the shin or instep.
Knee strikes: Any blow with the knee. A straight knee is usually delivered to the legs. A roundhouse knee follows a similar path to a roundhouse kick, and is often used against the opponent’s ribs or abdomen.
Straight punch: Straight punches with the knuckles of a closed fist include the jab, which is a fast, light strike used mainly in boxing and similar competitions; the lead straight, which is similar but lands with much more force; and the cross, which is a very powerful blow delivered from the rear hand.
Strangle: A strangle cuts off the blood supply to the brain, resulting in rapid unconsciousness and, if kept in place, death. A firmly placed strangle can cause unconsciousness in a few seconds.
Takedown: A takedown is a technique designed to make an opponent fall or to drive him into the ground.
