Then, few years later, he will folloz his head instructor Aaron ELBAZE in the system’s emancipation which has become today the Operative Israeli System. His seriousness, skill and professionalism are in time recognized around our region. He has trained numbers of student since all these years, and few articles and reports have been made about his school.
Always in search of improving his professionalism, Adrien SIWIEC keeps on learning and training in parallel : “Knowing how to provide a training is one thing, to understand it and explain it is another”
Adrien develops a new training style, without stereotypes ; he execute different exercises that he is validating bw his head instructor Aaron ELBAZE. Adrien is also the only one in our region to be trained both in France and Israël : when others are talking about sport club, he is insisting on a complete training addressed to civilians and professionals.
He is State graduate of Krav Maga from Israel and obtained it inside the Wingate (Netanya) under the direction of Avi AVISIDON.
It is really important to check the credibility of each instructors providing Krav Maga courses without being certified or only with other martial arts certification.

„I am not a dream seller: one does not joke with the security of the people trusting us…“ Because of his reliability and skills, he is in charge of developping the system in Switzerland.

Ludovic JOST

Instructor Degree 1

It is in 2011 that Ludovic is introduced to Krav Maga and Adrien SIWIEC. Shortly, with a dedicated and hard training allowing him to reach a certain level qualification, Adrien is offering him the chance to assist him for the teenagers class. That’s how his Instructor’s record begins.
After his validation of the Instructor’s “First Part” in 2013, he is taking over the kids class and teenagers class alongside with Adrien. Ludovic will then travel for a first course in Israel, and a second one in 2014, before completing his Instructor Course in July 2014.
Teach to kids, who are the future of OIS Krav Maga, allows Ludovic to improve his technical skills at the best, because to be able to train the youngest, one must first be able to perfectly master the technic to teach it back efficiently. The strength of OIS is in that each and everyone can defend himself with the exact same technic, and if a kid can do it, then an adult, man or woman, can do it too.
It is this wisdom that Ludovic is committed to provide to all students when it comes to teach OIS Krav Maga, and for what he keeps on training by following the courses, trainings and advices, in either OIS Krav Maga or guns shooting and handling.



Instructor degree 1

Seeking for skills improvement of my self-confidence and my independence, I have practiced combat sports and then krav maga before integrating the OIS krav maga. I came here for the realism, humility and pragmatism imposed by the operational field. This is the system which I judge to be able to stop an aggression. The key word is to avoid conflicts, but to be able to respond to it with force, determination and rapidity if it is necessary to. The main aspect is not the number of hours spent in training but the determination and the mind dedicated to avoid injuries when I deal with a dangerous situation. The OIS quickly becomes a mentality and a way of life.


Franco RIZZO

Assistant Instructor

In my work I have to cope with aggresion and violence regularly. More than the physical reinforcement and mind balance brought by the OIS krav maga system, it helps me every day to keep my composure and stay calm during tricky situations. The OIS system enables me to be ready to react in front of violence.

This system has finally been taught for two years in Switzerland. It is the most open minded and constantly updated method to bring the best solution to deal with physical involvements of any kind.

I would be glad to share my entusiasm about this useful self defense method. My motto: learn from each other and improve our knowledge.
