This forth coordinate is actually becomes tactical solutions because of its complexity. It is dependent on the first three: efficient methods of reach; the most efficient methods of using leverages to generate impact and block impact and leverage pressure points and escape from them; the limits of the human reaction time and the timing and limits of surprising an opponent managing to reach his pressure points without interference, and what is the best method to do it considering your body leverages, its reaction time, and no restricting rules.
But when you see someone just lunging and attacking with his rear leg or cross punch first, it is obvious that although he might succeed, he is not being efficient. His success would only depend of the lack of knowledge of his opponent to take advantage of this error!
Sometimes you see a perfect immediate knock out kick from the long range, and sometimes the fight moves back and forth within the kicking, punching and grappling ranges. Part of this pattern has to do with forgoing opportunities trying not to severely hurt the opponent, and part of it is due to ignorance losing an opportunity.
But when you see someone knocking his opponent out with a seesaw motion kick to the chin, a good side kick to the center body, a good front and back roundhouse kicks to the head or center body, or even the legs, a drop punch, hitting the liver, kidneys or the sides or back of the head in grappling scenarios you see an example of the tactics of Pure Krav Maga.
Of course they would be masked with the glove, with the limitations of obvious soft pressure points and the semi ignorance and limitation of applying immediate judgment for the amount of force to be used to dangerous areas of those that execute them.
