Reality based self defense systems and Krav Maga in particular have operated on the assumption that a good groin kick or eye gouge will end a fight or at least deter an attacker. While these are extremely important tool to have in your tool box, they are not the be all and end all of close quarter unarmed combat.
Inherited Wisdom from the Uninitiated:
Mostly this strategy of “Kick the Groin” and “Gouge his eyes” is derived from inherited wisdom, passed on from and by instructors with little real world experience. People unfamiliar with the effects of drugs and alcohol. These substances have an analgesic effect on a person. Not to mention the effect raw adrenaline will have in allowing a person to ignore or simply not feel pain in a critical moment.
Krav Maga, Jiu Jitsu, Combat Submission Wrestling, STX Kickboxing for the Toolbox:
Broaden and deepen your combatives tool box, when the time comes it will allow you to move from one technique or strategy to the next. When one fails immediately move to another. You never want to reach deep down and find nothing when it’s for all the marbles.
Eye Gouging CAN Work:
No doubt an eye gouge can be effective. However what it requires is burying your thumbs up to your knuckle in the eye socket. If you are not psychologically prepared to do that to another human being, your theory on “eye gouging” is largely just that, theory. What you will need to do to survive isn’t always what you have trained day to day. This kind of violence is difficult to simulate, so as an instructor one shouldn’t pretend you can simulate it when you can’t.
If I am in a dominant position over an opponent, who is in better position to eye gouge? The person dominating the position and the fight, or the person in the inferior position? The same goes for groin striking. If I am pinned in the bottom of the mount and I attempt an eye gouge, and it fails, my opponent will attempt the same or worse on me. This simply is not a viable strategy, I need legitimate skills around my “dirty tricks” to make them more effective. So get in, train, broaden the skill set, and always focus yourself in simulations to get the most out of it you can.
