You Deserve to Feel Safe. So Does Your Community.
You Deserve to Feel Safe. So Does Your Community.
The only person who is with you in every emergency of your life is you. You are your own first responder - so you should have the skills to keep yourself and the people you care about safe.
When the world feels unstable, and official responders can’t always be counted on, the strength of your community becomes your lifeline. Families, friends, and neighbors who are trained, prepared, and capable form the foundation of real safety.
Strong individuals build strong communities. Active Response Cross-training (ARX) gives you and your community the tools, mindset, and confidence to respond effectively - because everyone deserves to feel safe, no matter where they live.

What is ARX?
What is ARX?
ARX—Active Response Cross-training—is a community-centered safety and self-protection training initiative developed by David Mitchell, a certified instructor with the Civilian Tactical Training Association (CTTA). This isn’t one-size-fits-all training. ARX blends martial arts fundamentals with a comprehensive, trauma-informed approach to real-world safety. You’ll learn how to:
Spot and avoid danger with strong situational awareness
De-escalate conflict using verbal and nonverbal communication
Understand your rights and responsibilities through legal self-defense education
Defend yourself and others with reasonable force and practical techniques
Keep your family and community members safe, whether at home or in public
Build confidence, resilience, and connection—not fear
The name ARX was inspired by my background as a student of the Latin language. Meaning 'stronghold, citadel, refuge,' it seemed like the ideal term for the community-oriented program I wanted to build.
