The Russian Martial Art of Systema is different than your everyday martial arts. Rather than learning how to attack, Systema’s training is more focused on learning how to respond to an attack. The existence of Systema is believed to predate back to the cold war era in the Soviet Union, but actually has roots in ancient Russian fighting styles that existed more than a millennium ago.
The style is a fluid, reactionary style that focuses on individual strengths and characteristics. The main focus is to erase physical and mental tension from the fighting equation so that the fighter is prepared for the next move. There is also a fair amount of importance on the starting-stance in Systema. The starting stance should be straightforward and natural; there should not be any immanence of a threat. The stance should reflect the position at which your opponent is in, acting as a preventative method for your opponents next attack.
For example, Vladimir Vasiliev demonstrated the starting position. His attacker came at him, and Vladimir swiftly kicked him in the thigh and punched him in the back of the neck while falling to the ground. This was all done in one swift motion. The purpose of striking in Systema is to hit the attacker unexpectedly, causing un-balance rather than pain. This manipulation of the attackers body is premeditated so that the Systema fighter has the ultimate control. With this kind of control, the Systema fighter is able to work with moves that disorient his attacker without injuring him.
The next critical proponent of Systema is being able to move in a manner that is undetectable by your opponent. When the opponent is ready to strike, he gives a tell and begins the full movement of either a kick or a punch. Here, your opponent is already committed to the move at hand, making him vulnerable at the time of the attack. This is when you strike in Systema.
