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 our revolutionary General Physical Preparedness “GPP” functional fitness program for maximum results, using minimum equipment, in minimal time in each CKM class.
