Krav Maga (Hebrew: קְרַב מַגָּע , lit. "contact combat")
A self-defense system developed for the military in Israel; consisting of a wide variety of techniques sourced from Boxing, Savate, Muay Thai, Wing Chun, Judo, Jujutsu, wrestling, and grappling. Krav Maga is known for its focus on real-world situations and extremely efficient and brutal counter-attacks; as well as a philosophy emphasizing threat neutralization, simultaneous defensive and offensive maneuvers, and aggression. Derived from the street-fighting skills developed of Hungarian-Israeli martial artist Imi Lichtenfeld, who used his training as a boxer and wrestler as a means of defending the Jewish quarter against fascist groups in Bratislava in the mid-to-late 1930s. In the late 1940s, following his immigration to Israel, he began to provide lessons on combat training to what was to become the IDF, who went on to develop the system that became known as Krav Maga. Training has been refined for civilian, police and military applications. Krav Maga is used by Israeli Defense Forces, both regular and special forces, and several closely related variations have been developed and adopted by law enforcement and intelligence organizations, Mossad and Shin Bet. There are several organizations teaching variations of Krav Maga internationally.
