Evolution of Combative Anatomy

It has been just over a year since I coined the term Combative Anatomy, the study of incapacitating your attacker during a violent attack. Since that time I have done more research on the subject and have some new thoughts.

First, let's define incapacitation. For our purposes it means that the attacker is physically unable to continue to attack. Since the majority of initial defenses are likely to be open handed even against weapons, we cannot count on things like pain compliance because of tolerance or desensitization related to drugs or alcohol.

Defenses need to focus on the mechanism of attacks and not the method i.e., destroying the elbow of the arm that holds the knife instead of trying to disarm the knife.

Regardless of whether you are defending yourself with your hands, stick, gun, or firearms there are only two ways you can cause trauma to your attacker, and they are cutting and crushing. You either penetrate the skin or you don't.

The hierarchy of incapacitation is as follows-

- Central nervous system
- Skeletal system
- Muscular system
- Circulatory System

It is interesting to note that although trauma to the circulatory system is most likely to prove fatal it may actually be the slowest in terms on the immediacy in which it causes physical incapacitation that stops your attacker. With the exception of choking, targeting of the circulatory system is also impossible with the personal or impact weapons.

Instead of having a specific game plan or secret move, I feel it is more effective to target areas of the body that are most vulnerable to open hand attacks that are likely to be exposed during an altercation.

These targets have been narrowed down to-

Head- responsible for decision-making
Elbow- the lynch pin of all open hand attack and using weapons
Knee- responsible for locomotion, base and balance

The way to combat the failure of specific targeting is redundancy. Since an attack with the open hand or a contact distance weapon would expose all three primary targets, all should be attacked if possible. For example, if someone were to attack you with a tire iron and you were able to move to the outside you would- smash the weapon side elbow with your elbow or palm, smash your knee into the side of theirs and then yank them back causing their head to strike a wall or vehicle.

This of course is an example in open hand force vs deadly force. A slap to the side of the head is also an effective optional technique. Disruption of the central nervous system should be considered the primary target even if it is not attacked first.

This doctrine allows for a measured open hand response that because of its effectiveness may prevent the need to escalate to a mechanical or deadly force option. As a side note, practicing these techniques even in a controlled environment is likely to result in hyper extended knees and elbow. Headgear should also be worn. Communication with your training partner is the key.

Now a few words on Combative Anatomy as it relates to the use of an edged weapon for personal protection. Again it seems that our goal needs to be defined as stopping our attacker as fast as possible, not killing them eventually. The debate over stab vs cut continues.

Since attacking the central nervous system with an edged weapon is improbable we will discuss the most effective way to attack the circulatory system. Most of those knowledgeable and trained in edged weapons prefer to stab and believe they will be able to do so even when attacked. Since I believe that the vast majority of people reading this are likely to never use an edged weapon offensively, I can only theorize that if they do have to use one it will be in response to being attacked.

My research has shown that when people are on the defense and moving to the rear they are more likely to slash. The people that I have observed have ranged from novices to those who would define themselves as seasoned knifers. Either way they responded the same way.

This is telling since it has been my experience that many folks who carry a knife for self defense have little to no training and consider their knife a last ditch weapon. What I teach has to be as effective for those who attend a weekend seminar as it is for those who pursue edged weapons as a martial art. For this reason I don't feel comfortable teaching stabbing as a primary counter attack.

For those of you who don't hunt, try watching a few hunting shows. You can see hunters shooting white tail dear with shotguns, rifles, and bows. I don't think that anyone would argue that a knife would cause more damage than any of these other weapons. Their shots usually target the circulatory system. Most of the time the animal recoils in shock before bolting off to die a distance away. How much damage could a human do in that time? This overwhelming trauma to the thoracic cavity results in an adrenaline dump and blood pumping into the legs allowing the animal to run.

They are for a few seconds able to run faster on their extremities than they ever have before. Why don't they target the head and the central nervous system or the skeletal system? One is for the trophy and one is sportsmanship. It is more important to kill them eventually than to stop them immediately. The exact opposite of what we need to do when defending ourselves against human predators.

These theories on Combative Anatomy continue to reinforce my belief that Inverted Edge Tactics offer the best defensive edged weapon skills.

First of all the use of the inverted edge prevents people from swinging wildly outside the silhouette of their attacker which increases economy of motion, while at the same time targets by default the inherent weaknesses of the body.

The most important feature of Inverted Edge Tactics is that it takes advantage of the fact that arteries and nerves run together along the contours of the muscle like a wiring harness. As with the open hand this combats the likeliness of failure with redundancy. The more systems attacked the better the chance of physiological failure.

Careful consideration needs to be made in reference to how humans respond during stress, the positions we are likely to find ourselves in, and the most effective way to blend those things to formulate repeatable tactics to stop attacks as fast as possible.
