"contact-combat") is a military self-defense system developed for the Israel Defense Forces (IDF) and Israeli security forces (Shin Bet and Mossad) that consists of a combination of techniques sourced from Boxing, Wrestling, Aikido, Judo, Karate along with realistic fight training.  Krav Maga is known for its focus on real-world situations and its extreme efficiency and brutal counter-attacks.  It was derived from the street-fighting experience of 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 migration to Israel, he began to provide lessons on combat training to what was to become the IDF.
