Rapid Assault Tactics (R.A.T.) is a self-defense system developed at the request of United States Navy. This very efficient technology is one example of why military special forces from Israel, Russia and Germany try to emulate the most skilled fighters in the world, the U.S. Special Forces. The R.A.T. was developed specifically for the U.S. Navy Seals as a primary combative program based in Jeet Kune Do martial arts. Rapid Assault Tactics focuses on identifying phase (or range) in which an attack situation is occurring and responding to it with appropriate tools, typically using the HKE approach (headbutts, knees, and elbows). These new skills were specifically designed for situations where elite special forces suddenly found themselves without a gun or even a pocket knife... possibly wounded... surprised by ambush... out-numbered... and with the violence around them reaching the point of life and death! In short, a situation where everything was completely chaotic! A situation much like you might find in the street, where you might suddenly find yourself attacked unexpectedly.
