Do you need to be a martial arts expert or have special forces training to survive an attack by a gun or knife?
No. You need to be able to get past denial and assess the situation. You need a plan. You need to have walked through it and have had some basic training. You need to know if you can escape, deny, or attack back. You need to Move and do one of these three options immediately with commitment.
I teach all kinds of people how to survive. Sure, I also teach martial art classes and help people achieve their black belts in the Korean self-defense art of Hapkido, but that is not required to be a survivor. The strategies and tactics in the Survive a Shooting course focus on simple things than anyone can learn and implement.
You can survive!
