WHAT STUDENTS ARE SAYING...
As a prosecutor with over twenty years of experience, I never imagined I would find myself on the other side of violence. Yet when I was suddenly attacked by accused persons, I froze. It wasnβt until I trained under Adam and his HAVOC system that I finally understood what had happened to me, and how to make sure it never happens again. HAVOC is not just about self-defense; itβs about mastering the mindset required to survive a violent encounter, even against the most dangerous offenders.
Sylvia R
Very impressed with the videos so far. As a disabled vet they could really come in handy, although Iβm hoping I never have to use the system. Men are always supposed to be the protector and this just might give me the edge if Iβm ever in a situation where I need to protect my family or loved ones.
Roger H
I have purchased this program and am going through it now. I have studied TKD and Aikido. I know what they are talking about when they talk about typical martial arts training vs what works in the street. So far, this is very down-to-earth stuff. I am looking forward to practicing it and making it muscle memory.
Scott G
I am currently going through your HAVOC program. I am 62 with 45 years of martial arts, 24 years of military, and over 40 years of LE and security. It is simple and effective, and someone my age can easily perform these techniques. I love it.
Derek S
As a fellow martial artist I respect the fact that you invested the time to produce Havoc. It takes a lot of courage to put together a program like this. Itβs absolutely commendable. I think HAVOC is ideal for someone with little or no formal training.
Gary M
First & foremost, THANK YOU for serving and protecting OUR freedom! Second, I bought the program and am impressed with the quality and length. VERY well done.
Joe F
Adam β this course is exactly what I have been looking for. After lots of BJJ and Muay Thai/Boxing, I never felt prepared for the street. This sealed the deal for me. The modules on fear and situational awareness are worth the cost of the program by themselves! Thanks again!

THE TRUTH ABOUT GROUND FIGHTING IN A REAL ATTACK
Most self-defense experts will tell you to avoid the ground at all costs in a street fight. They're right. But what happens when you don't have a choice? When you slip, get tackled, or your attacker drags you down? You need skills that actually work under extreme stress.
WHY SPORT GRAPPLING GETS YOU HURT
Most grappling systems... Brazilian Jiu-Jitsu, Wrestling, Judo... are built for competition with rules, referees, and safety measures. They require years of training to become proficient. They teach complex movements that demand athletic ability and extended rolling sessions on soft mats. But real ground fighting is brutal, chaotic, and happens on concrete or broken glass. Sport techniques assume a one-on-one fight with no weapons. In reality, you might face multiple attackers, hidden weapons, or accomplices looking to stomp your head while you're tangled up.
THE GROUND SURVIVAL GAP
Even experienced grapplers freeze when the stakes change from points to survival. Tournament-tested moves disappear when your heart rate spikes past 145 beats per minute and panic sets in. You need techniques so simple and brutal that your body can execute them even when your conscious mind shuts down. Skills designed for escape and survival, not for winning matches.
WHAT ACTUALLY WORKS WHEN YOU HIT THE GROUND
Ground Zero was forged in real combat scenarios by special operations professionals. Developed by elite operator Adam Seegmiller and BJJ black belt Andrew MacDonald, this system contains only what actually works when you're fighting for your life on the ground. No sport rules. No point scoring. No theory. Instead of spending years becoming proficient in a traditional grappling art, you can master these techniques in a matter of days.
BUILT FOR GROUND SURVIVAL
Ground Zero 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 and flexibility, you learn straightforward techniques designed to escape or end the threat immediately. These skills don't vanish under stress. They're designed for chaos, concrete, and survival.
WORKS FOR EVERYONE
Ground Zero doesn't rely on strength, speed, or athleticism. The system uses leverage, positioning, 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 recognize danger and avoid the ground entirely, 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.

ADAM SEEGMILLER
Elite Special Forces, Close Protection Operator
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 environmentsβwhere my survival depended entirely on my hand-to-hand combat capabilities.

FREQUENTLY ASKED QUESTIONS
I have no martial arts or self-defense experience. Can I still learn GROUND ZERO?
Absolutely! GROUND ZERO was specifically designed to be learned quickly by people with zero prior training. The techniques are simple, intuitive, and based on your body's natural movements.
I'm not in great physical shape. Will GROUND ZERO still work for me?
Yes. GROUND ZERO doesn't rely on strength, speed, or athleticism. It uses strategic targeting and leverage principles that work regardless of your physical condition.
How long will it take me to learn these techniques?
The core techniques can be learned in a single weekend. With just a few hours of practice, you'll develop skills that can save your life in a real confrontation.
Is HAVOC legal? Some of these techniques sound extreme.
GROUND ZERO teaches you to use appropriate force based on the threat level. We cover legal considerations extensively in the training. Remember, in a true life-or-death situation, your priority must be survival.
How is this different from Krav Maga or other self-defense systems?
While there are some similarities to other reality-based systems, GROUND ZERO has been refined through actual combat experience with special operations units. We've eliminated techniques that don't work under extreme stress and focused only on what has been proven effective in real-world violence.
