Complicated techniques break down under stress. HAVOC, developed by a special operations veteran, arms you with easy-to-learn and devastatingly effective skills that end violence in seconds no matter your age or strength.
PROTECT YOURSELF NOW







One in five people will be the victim of a violent crime this year. Police take an average of fifteen minutes to arrive. But most attacks are over in just seconds. Calling the police and waiting for help is not a good plan.
Most people turn to martial arts, self-defense programs, firearms training, or tools like pepper spray. These solutions seem logical. But they all share a fatal flaw: they fail when your heart rate crosses 145 beats per minute. Complex techniques vanish. Fine motor skills shut down. Your ability to aim, draw a weapon, or execute intricate moves disappears under the flood of adrenaline and stress.
Even worse, most self-defense systems assume capabilities many people don't possess. They're designed by and for young, fit, athletic men. If you're smaller, older, or facing someone bigger and stronger, these systems offer little help. You need something simple (and aggressive) that your body can execute even when your mind is overwhelmed by fear and adrenaline.


HAVOC was forged in hundreds of real fights, from the most violent biker bars to the battlefield. Developed by a special operations veteran, this system contains only what actually works when your life is on the line. No rituals. No belts. No theory. Instead of spending years becoming proficient in a martial art, you can master these techniques in a matter of days.
HAVOC is based on gross motor patterns your body can perform instantly when adrenaline spikes. Every technique works at 145 beats per minute and above. Instead of complex sequences that require perfect timing, you learn straightforward techniques that overwhelm attackers faster than they can react. These skills don't vanish under stress. They're designed for chaos.
HAVOC doesn't rely on strength, speed, or athleticism. The system uses leverage, targeting, and decisive aggression to shut down violence in seconds regardless of your age, size, or physical condition. You also learn mindset, situational awareness, and proprietary techniques taught by special operations to spot danger and avoid it, so you never have to use the physical skills. You gain confidence, control, and a proven method to protect yourself and the people you love when nothing else will.

As a highly trained member of Canada's elite Special Operations units, I've been deployed to combat zones across the globe, engaging in direct-action missions, intelligence gathering, and unconventional warfare.
I've mastered close quarters combat (CQC), the highly specialized discipline of engaging enemies in confined spaces where split-second decisions and precision are critical. My expertise extends to the integration of advanced firearms tactics, hand-to-hand combat, and edged weapons.
Throughout my career, I've worked alongside other elite units including U.S. Navy SEALs, Delta Force, British SAS, and Australian SASR, sharing and refining tactics that span across military and law enforcement boundaries.
But what truly sets my experience apart is the time I spent operating without weapons in hostile environments—where my survival depended entirely on my hand-to-hand combat capabilities.

Joining me is Andrew MacDonald, a distinguished Brazilian Jiu-Jitsu black belt under Wagnney Fabiano and Leo Santos, with over two decades of martial arts experience. Andrew's journey began in 2001 with Sanda (Chinese kickboxing) before transitioning through MMA and Sambo to Brazilian Jiu-Jitsu, where he found his true calling.
He's competed at the highest levels, including the Abu Dhabi Jiu-Jitsu Pro Tour as a black belt.
In 2014, Andrew co-founded Arete Brazilian Jiu-Jitsu in Bangkok, Thailand, creating a hub for BJJ enthusiasts and developing a teaching philosophy that emphasizes technical precision and practical application.
Andrew's expertise in stand-up and ground fighting provides the perfect complement to my direct-action combat experience, ensuring HAVOC addresses every aspect of real-world self-defense.
