The Mastro Defence System is a professional defense and control system, created by Frédéric Mastro, based on the experiences of private and public security professionals. The general philosphy of MDS is that an individual or professional practitioner, will appropriate a reactionary response that is proportional to the level of risk and attack. This makes MDS an ideal tool for anyone working in the field of private or public security or individuals wanting to learn self-defense.
