Introduction: At Modern Era Warrior's Reality Based Self-Defense and Fitness, we have combined Commando Krav Maga (CKM), the most devastating, reality-based defensive tactics system, and Gracie Jiu-Jitsu (GJJ), the most effective grappling system, into the most complete self-defense system designed to prepare any individual for real combat in the shortest time possible. We also incorporate elite combat fitness (ECF), revolutionary fitness and conditioning, into each CKM class.
