The discussion is with an answer to a question of how Krav Maga is different or better than a number of arts such as; Jiu Jitsu, or Judo, or Boxing, or Karate, or Muay Thai, or various other martial arts out there. For me it's; What is the difference between Krav Maga and other martial arts? I don't even want to relate to the question whether Krav Maga is better than other arts, because better is what is better for the individual in the physical fitness that he chose to involve himself in.
So, we can just touch on how Krav Maga is different than other arts. Krav Maga is an art that is taught only for the purpose of self preservation. It is not a competitive art. We don't design to fight with people in the same weight class. We don't design to fight in the same sex. We don't design to fight even one guy. We are preparing for war. Period. We are preparing our self as an art to a time when you have to fight to defend yourself. The choice of not defending yourself is unacceptable because you potentially could lose your life.
That is the difference. We are allowed to do whatever is necessary to cause the max amount of damage on one individual. We want to do it in the shortest period of time, because the longer it goes the more hurt we're going to be. Our job is simply to function as a soldier, to conduct combat, and when it's done to extract our self out of there.
Our entire concept of thinking is different than competitive arts. Our entire way of training is different than competitive arts. And the reason is simple; we do not compete; we fight for survival.
