Krav Maga is a self-defense system developed for the military in Israel that consists of a wide combination of techniques sourced from boxing, savate, Muay Thai, Wing Chun, Judo, Jujutsu, wrestling, and grappling, along with realistic fight training. Krav Maga has a philosophy emphasizing threat neutralization, simultaneous defensive and offensive maneuvers, and aggression. 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.
