Systema (Система, literally meaning The System) is a Russian martial art. Training includes, but is not limited to: hand-to-hand combat, grappling, knife fighting, and firearms training. Training involves drills and sparring without set kata. In Systema, the body has to be free of tensions, filled with endurance, flexibility, effortless movement, and explosive potential; the "spirit" or psychological state has to be calm, free of anger, irritation, fear, self-pity, delusion, ego and pride. Systema has four pillars - Breathing, Relaxation, Body Position, and Movement, as well as utilizing an attacker's momentum against him and controlling the six body levers (elbows, neck, knees, waist, ankles, and shoulders) through pressure point application, striking, and weapon applications. As a discipline, it is becoming more and more popular among police and security forces and it is taught by several practitioners inside and outside Russia.[3][citation needed] There are multiple schools of Systema - Systema Kadochnikova, Systema Ryabko, Systema Vasiliev.
