Krav Maga /krɑːv məˈɡɑː/ (Hebrew: קְרַב מַגָּע [ˈkʁav maˈɡa], lit. “contact combat”) is a self-defense system developed for the military in Israel that consists of a wide combination of techniques sourced from Aikido, Judo, boxing and wrestling along with realistic fight training. Krav Maga is known for its focus on real-world situations and its extremely efficient and brutal counter-attacks. It was derived from street-fighting skills developed by Hungarian-Israeli martial artist Imi Lichtenfeld, who made use of his training as a boxer and wrestler as a means of defending the Jewish quarter against fascist groups in Bratislava, Czechoslovakia 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. It has since been refined for civilian, police and military applications.
Krav Maga has a philosophy emphasizing threat neutralization, simultaneous defensive and offensive maneuvers, and aggression. Krav Maga has been used mainly by Israeli Defense Forces, special units and reconnaissance brigades and recently by regular infantry brigades, 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.
