Krav Magais a self-defense and military hand-to-hand combat system developed in Israel. It came to prominence following its adoption by various Israeli Security Forces and is now used by military and law enforcement personnel, as well as civilians, around the world. The Krav Maga taught in civilian self defence classes is more often a simplified version that emphasizes personal self-defense, and excludes numerous 'more lethal' techniques taught to the military, plus holds and come-alongs taught to police forces- as there are legal proscriptions in some countries which govern and constrain the teaching of hazardous or life-threatening techniques to civilians.
