In A Life-Or-Death Scenario, When Seconds Matter, The Police Are Minutes Away.

Most people are completely unprepared for the raw, chaotic nature of real-world violence.
Traditional martial arts look impressive in the dojo but fail catastrophically on the street. MMA training requires years of dedication and peak physical condition. And most self defense classes? They're giving you a false sense of security that could get you killed.
Our society is becoming increasingly chaotic. Political turmoil feels like it's a day away from all-out anarchy. Random acts of violence are surging across the country. Home invasions, carjackings, and street attacks don't follow rules or give you time to prepare.
Most combat systems were designed for sport competition or theoretical scenarios—not for the brutal, no-rules reality of a life-threatening attack.
You need something different. Something that works when everything goes wrong.
When your life is on the line, you need a system built for reality, not the dojo.
HAVOC isn't another martial art. It's not a sport. It's a meticulously engineered combat system developed by Adam Seegmiller, an elite Special Operations Vet who spent one-third of his military career as a high-threat bodyguard in hostile environments where he wasn't authorized to carry weapons.
HAVOC was designed specifically for the worst-case scenarios that other systems ignore: multiple attackers, confined spaces, weapons, and the psychological freeze that happens during real attacks.
The same techniques that have saved lives in combat zones are now available to civilians in a format that can be learned in a single weekend.
HAVOC will.
While traditional martial arts and MMA schools focus on tournaments, points, and rules, HAVOC focuses exclusively on what works when your life is on the line.
The HAVOC difference isn't just in what we teach, but how we teach it. Every technique has been battle-tested, stripped to its essential components, and refined to work under the worst possible conditions.
This isn't theory. This is survival.

Adam brings over two decades of elite military experience to HAVOC. As a veteran of Canada's elite special operations units, he has served in combat zones across the globe, supporting critical missions and high-stakes operations.
During his military career, Adam spent one-third of his time as a high-threat bodyguard in hostile environments where he wasn't authorized to carry weapons. This experience proved critical – he knew he needed devastating hand-to-hand techniques that would work instantly against armed attackers when his life and the lives of his clients were on the line.
His expertise in close quarters combat (CQC) was forged in the most dangerous environments on earth, where split-second decisions mean the difference between life and death.
Adam has trained alongside elite units including the U.S. Navy SEALs, Delta Force, British SAS, and Australian SASR, giving him an unparalleled understanding of combat tactics that work when failure is not an option.
After years of testing various martial arts systems in real-world violence, Adam developed HAVOC to address the critical flaws in traditional training methods. His system has been taught to military personnel, law enforcement officers, and civilians who need reliable self-defense skills that work immediately.

Andrew brings over 20 years of martial arts experience to HAVOC. As a distinguished Brazilian Jiu-Jitsu black belt under Wagnney Fabiano and Leo Santos of Nova União International, Andrew has competed at the highest levels of the sport.
His martial arts journey began in 2001 in China with Sanda (Chinese kickboxing) before transitioning to MMA, Sambo, and eventually Brazilian Jiu-Jitsu.
In 2014, he co-founded Arete Brazilian Jiu-Jitsu in Bangkok, Thailand, creating a hub for serious combat sports training.
Andrew's extensive background in both traditional martial arts and real-world application gives him unique insight into what works—and what doesn't—when lives are on the line. His teaching philosophy emphasizes technical precision, practical application, and the underlying principles that make HAVOC so effective regardless of the student's size or strength.
Together, Adam and Andrew bring complementary expertise that makes HAVOC the most comprehensive, effective self-defense system available to civilians today.

HAVOC isn't just another self-defense course. It's a complete system for surviving the worst day of your life. Here's what you'll master:

The most important part of walking away alive is what happens before the fight. We'll show you how to identify threats early, control proximity, and position yourself for maximum advantage in any environment.

Ridiculously simple and effective techniques like "Ocular Control" and the "Russian Attack Method" use violence of action to help you take out any attacker - from the loudmouth at the bar to a life-or-death home invasion.

From "Caging" to "SPRAT" - How to not get caught off guard and what to do if you are. These techniques work with your body's natural stress response, not against it.

From elevators to vehicle attacks, we'll show you how to defend yourself when retreat isn't an option and traditional techniques fail. Master the specialized tactics that work when you're trapped in the worst possible scenarios.

Most self-defense systems fall apart against multiple attackers. We'll teach you the proven methods to control, neutralize, and escape when out numbered - the scenario most martial arts completely ignore.
The HAVOC system is delivered as a comprehensive video course you can access immediately after enrollment. Here's exactly what you'll receive:
"I am always looking for effective training that will give my troops an edge over the numerous threats that members of the Canadian Armed forces (CAF) are faced with on a daily basis- be it at home or abroad.
I brought him in for single day of training at a local facility, to train Members of my unit who had little to no experience.
I can honestly say that the response from my troops was overwhelmingly positive. Adam's instructional technique, approach, drills, trade secrets and experience he has developed over his number of years of service coupled, with his special forces training, proved to be a no BS brutally effective hand to hand fighting system that I had not been exposed to in my 25+ years as an Non Commissioned Member (NCM) in the Combat Arms. To this day I have Troops asking me “when is Adam coming back to kick our ass?”
For anyone wishing to learn effective hand to hand combat in a short period of time, Adam's Fight Program is the only system I would recommend"
"He is one of Canada's best use of force trainers that I know of"
“I have been training in various martial arts for years, but never felt like I was ready to handle a dangerous situation. Adam’s approach to violence is like nothing I have ever seen before. The techniques he teaches and more importantly, the mindset he teaches is life changing. I feel more ready than ever. I wish I would have found this course sooner."
We're so confident in the effectiveness of HAVOC that we offer a simple, no-questions-asked guarantee:
If you don't feel significantly more prepared to handle real-world violence after completing the HAVOC system, we'll refund your entire purchase price.
No hoops to jump through. No fine print. Just a straight forward promise that HAVOC will deliver the self-defense capability we claim it will.
We can make this guarantee because we've seen HAVOC work for countless students—from military personnel to grandmothers—regardless of their previous experience or physical abilities.
This isn't just training. It's life insurance you can actually use.

Most martial arts and MMA schools charge $150+ per month for training that takes YEARS to become effective in real-world situations.
Over a decade, you're looking at an investment of $18,000+ for skills that might fail you when you need them most.
HAVOC delivers more practical self-defense capability in a single weekend than most systems teach in years—and at a fraction of the cost.
That's less than the cost of a single month at most martial arts schools, for a system that works immediately when you need it most.
Remember: Violence doesn't announce itself with a warning. It strikes when you least expect it, giving you just seconds to react. In today's increasingly chaotic world, being unprepared is a risk you can't afford to take.
Every day, thousands of people become victims of violence because they weren't prepared.
Don't let yourself or your loved ones become another statistic.
In a life-or-death situation, when seconds matter, no one is coming to save you. You must be prepared to protect yourself and those you love.
For just $97—less than the cost of a decent dinner for two—you can gain access to the same combat system taught to elite special forces operators around the world.
This is your chance to transform from potential victim to confident protector.
HAVOC isn't just training. It's the insurance policy you hope you never need to use—but will be eternally grateful for if you do.
REMEMBER: When violence erupts, you have just 3 seconds to react. Traditional martial arts will fail you. Your fine motor skills will collapse. And the police will still be minutes away. The only person who can save you is YOU—but only if you have the right training.
