Sayeret Hagana Atsmit is another name for Ryukyu Kenpo Kobujutsu. It comes from one of the oldest, and most effective, military combat systems ever developed. The system is designed for adults and mature teens. The training is difficult, dangerous, and demanding. It takes perseverance, high motivation, a good mind, and, an unwillingness to compromise standards. The system teaches violence control and prevention recognizing that "self-defense" is a misnomer utilized to circumvent the ugly truth that it takes violence to stop or repel violence. Improvised as well as standard weapons are included in the training, where possible. It was meant to supplement a soldier's battlefield repertoire of techniques and ideas to keep him alive and functioning in that hostile environment. As a result this system is not for exercise or sport. Taught in near secrecy in Israel for more than three decades, it was opened up in 2023 for civilians and the rest of the world to have the ability to learn it in its entirety.
