WARRIOR READY. WARRIOR STRONG. WARRIOR FORGED.


Our Story
At Zaram Karabah Combat Systems, Grandmaster (GM) David McJimson blends the timeless wisdom of traditional martial arts with the demands of modern-day self-defense.
Our system draws from Krav Maga, Panantukan, Silat, Filipino Martial Arts, Wing Chun, Jeet Kune Do, and traditional Budo—creating a versatile, practical approach to personal combat and defense.
With expert instruction, innovative training methods, and a strong foundation in martial values, we develop adaptable, confident, and disciplined practitioners ready for the real world.
Our vision is to build a connected global community of martial artists—united by tradition, driven by progress, and empowered to train anytime, anywhere.
Because self-protection takes many forms, ZKCS also offers in-person firearms training—giving students the critical skills, mindset, and confidence to stay prepared in every environment, both armed and unarmed.
TESTED. TRIED. PROVEN.

LET'S GO!
ZKCS offers a progressive series of online curriculum designed to build skill, confidence, and real-world readiness at every level.
Through consistent practice, students improve endurance, flexibility, balance, coordination, and sharpen both physical and visual reflexes—enhancing reaction time and overall awareness for natural self-defense.
Our subscription curriculum is based on the Patakbasapakan System and is structured into three progressive levels: Beginner, Intermediate, and Advanced. Students must complete each level in sequence, ensuring a solid foundation in core techniques before advancing to more complex skills and concepts.
This clear progression path supports steady growth, deeper understanding, and long-term martial development.
In addition to our tiered subscription program, we offer non-subscription options—single purchase videos in select areas for added flexibility and focused learning.

LIFE-CHANGING TESTIMONIALS
Sedric, TX
ZKCS has changed my life in more ways than one. I was overweight, out of shape, had no energy, and was in pain daily from atrophy due to sitting 8 hours a day in a dead-end job for 13 years, to the point my muscles forgot how to RUN. This is from a guy who played basketball nearly 8 hours a day in my early years. All of that has changed, thanks to ZKCS! I am more agile, my energy levels have risen dramatically, and my physicality and endurance have grown exponentially. GM McJimson and ZKCS has LITERALLY brought me back from the brink, and I'm only getting stronger! This FAMILY has saved my life, and I could never thank them enough!

Before I got into training, I thought I knew what it took to train. I was an athlete and prepared myself in the mental aspects of inner martial arts, as you’d say. But GM McJimson has a way of pushing you to a point where the battle is nowhere else but inside of you. This is why I started, and how I started, that feeling of internal challenge; I was afraid of it, and I knew I had to overcome it. So I chase it every day; for me, it’s not just about learning how to fight physically; it’s teaching me practically how to develop into who I’m meant to be. To accept the challenges and trials I will inevitably face and use them to propel me forwards. I’m glad the Most High blessed me with people who are willing vessels to do his work. GM McJimson is one of those people. If you can stick with it and truly embody the principles, it will bring a change to your life.

I realized quickly that ZKCS isn’t just a martial arts school—it’s a place of real transformation. GM McJimson has a rare and powerful gift: he meets you exactly where you are, no matter your background or skill level, and guides you with wisdom, patience, and precision toward where you need to go! It’s not just about learning techniques; it’s about growing into the best version of yourself! That’s exactly what ZKCS offers—more than developing physical skills; the training has pushed me to become physically healthier, build stronger discipline, sharpen my focus, and strengthen my mindset. The environment is both challenging and supportive, and every class encourages growth. You learn to face challenges head-on and use them as fuel to keep moving forward. You don’t just train here—you become part of a family. I am grateful to the Most High for GM McJimson and the ZKCS family!

Training under GM McJimson at ZKCS has helped me become more confident and focused, not just in martial arts but in school and life, too! GM McJimson is encouraging — he makes it fun, but also pushes you to be better every time you show up. I’ve learned discipline, awareness, control, and how to set goals and not give up. I feel stronger every week and am excited to keep moving up!

GM McJimson has shown me what discipline exemplifies in everyday life and being aware of your surroundings. He always encourages us as students to keep pushing through no matter how hard it gets. This school has taught me more about patience, endurance, and adversity, whether in our everyday lives or just the battle within ourselves. GM also teaches us everything is about control and consistency. I recommend this school to everyone who is looking to become the best version of themselves.
