The Grandmaster has developed his system of (RSD) Tactics which has been tested in combat by elite units of the IDF and in assisting some other countries who have approached Israel for help.
RSD is a trimmed down simplified version of Abir® for elite security/military /police personnel. RSD is NOT for the public!
Yehoshua Sofer is the creator of Abir® Israelite Warrior Arts (in its modern form) which is the result of his life long study of martial arts. Abir® includes Sofers' strategies and unique concepts of motion, energy, placement or spaciality, use of balanced force and his use of the Hebrew alphabet and the symbols of the 12 Tribes of Israel to classify or categorize martial arts training into a very clear digestible "user friendly" format. Sofer has a school and is presently looking for talented people who can assimilate his Abir® system in an intensive program designed to fill the demand for qualified instructors to teach his system with its instructional methodology.
Yehoshua Sofer is the official representative of the Korea Kuksool Association, The World KIDO Federation and the newly formed HanMinJok Hapkido Association approved as the governing body for Korea's traditional martial arts by the S. Korean Ministry Of Culture in Israel and on the European continent.
