Force Multipliers In Street Self-Defense.

Anyone, at any time, can face the reality of the pain-resistant opponent. Drugs, alcohol, adrenaline, and even some forms of mental illness can render many pain-reliant techniques ineffective.

In the 1970s, there were the stories of people high on cocaine or PCP ("angel dust") running on broken legs. In Brazilian Jiu-Jitsu circles, it is common to see people who refuse to tap out despite the pain and damage being done to a particular limb. Those who believe in and advocate the use of specific pressure points and meridians to incapacitate others have to admit that those techniques have better success on the opponent who is adrenalized only; not adrenalized, and intoxicated on drugs and/or alcohol, and/or psychotic. They also work better on an opponent who is not moving; many of those techniques require expert precision, according to their proponents.

The same could be said of the "one strike/one kill" concept. A todome (or 'finishing technique') is more likely to have maximum effect on a stationary target. There is a reason boxing and other combative sports emphasize foot work, angles, and head movement: blows that don't land directly on target usually don't produce a knockout (or broken bones and/or ruptured organs).

This is also true of a target moving away from the impact as the blow lands. A strategy used by Thai boxers, for example, is to stay just outside of the range of a jab, so that it lands with a majority of the power dissipated, so it may look as if the blow had 'trembling shock', and the glove makes a very loud sound as it lands, but the fighter is in fact unharmed, and soon mounts a counter-attack as the opponent over-commits, based upon misreading the actual situation.

All these examples tell us that multiple strikes will most likely be required. And, given type of threat posed, specifically the pain-resistant opponent, every strike must count.

Force multipliers are techniques or actions that increase the effect of a strike or throw.

Concussive force, specifically when the human brain ricochets inside of the skull, is what allows for knockouts to occur (also potential brain damage or death). In the 'moment of truth', against a pain-resistant, adrenalized opponent, every technique must be decisive; especially if a weapon is involved.
