Retzev Part I 

If you must fight, identify the opportune moment to attack the attacker with a continuous overwhelming counterattack using retzev or “continuous combat motion.” Combined with simultaneous defense and attack or near simultaneous defense and attack, retzev is a seamless, decisive, and overpowering counterattack forming the backbone of the Israeli fighting system. Retzev may be understood using combined upper- and lower-body combatives, locks, chokes, throws, takedowns, and weapons interchangeably and without pause.
Exert maximum speed and aggression. Your goal is not to definitively win a fight, but, rather, to escape. Never forget that the level of force you use to defend yourself should be commensurate with the threat. Once the threat is no more, you must cease counteroffensive actions. The krav maga system is designed to conform to you. You do not need to conform to the system or adopt any rigid, set solutions. To be sure, there are preferred counterattack methods using retzev to prevail, but you must react instinctively to the best of your ability.
