Real violence doesn't follow rules. Neither does this.

Easy-to-learn online courses built on what kept Adam alive in Iraq, Afghanistan and close protection work. Simple moves you can pick up in a weekend, at any age, that still work when your heart is pounding and your hands are shaking.

Two ways a bad night goes. Be ready for both.

Most confrontations can be talked down. Some can't. DIFFUSE is for the first kind. HAVOC is for the second. Start with the one that keeps you up at night.

Why it works
"If it's complex, you're not going to do it when someone's trying to kill you."Adam Seegmiller
Built for adrenaline

When the adrenaline dump hits, fine motor skills go. Every move here uses the big, simple movements your body still has when you're terrified.

Over in seconds

Real fights are decided in the first 15 to 30 seconds. Every technique fits inside that window, and you can learn them all in a weekend.

Filtered by real violence

Combat zones, close protection, the Tier 1 fight team. One filter on every technique: does it work when you're scared, exhausted and surprised? Only what passed made it in.

From students

Martial artists, vets and cops bought it too.

"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."

Dr. Derek S.HAVOC student

"The simple, gross motor methods it teaches were easily learned and upped my confidence for real-life violence greatly in a short period of time."

Joel L.BJJ student, HAVOC student

"This program is very solid and very in line with the realities that face most people in a confrontation... I'm quite happy with it."

Dr. Chad P.HAVOC student

"HAVOC is a very worthwhile course. It prepares you for tackling bad stuff and really makes you think! As a martial artist of 19 years training I can highly recommend it!"

Tim H.Sensei, 19 years of martial arts
