Hi, my name is Mario Castillo.
I spent 15 years in the military and I've done
two tours overseas. My first mission was in Kosovo in
2005/6 and my second mission was in Iraq in 2009/10.
On both missions, I was a combat medic attached
to an infantry unit.
In 2015, while working for a hospital in Northwest
Houston, a security guard told me that if she
encountered an active shooter, she would remove her
shoe and throw it at him in the hope that she
would knock the gun out of his hand. She went on
to say that she would then run as fast as she
could away from the shooter. This upset me, of
course. That night I spent about five hours creating
the embryonic version of what I teach today. I
spent the following six months enhancing that model.
It’s important to know how to survive an active shooter
scenario without weapons for a couple of reasons. First,
most organizations don’t allow their employees to carry guns.
Consequently, my approach gives the unarmed individual specific
tactical options used in combat zones around the world.
Second, it may take quite some time for police to arrive on the scene.
I've designed my Training for Tactical Thinkers (T3) program
so that individuals are not powerless while they wait on law enforcement.
T3 can be taught in four or eight hours. In both classes,
we focus first on the strengths and weaknesses of both the
shooter and the unarmed individual. The intention is to
demonstrate how much power the unarmed individual actually has,
contrary to popular thinking. We then teach movement as a strategy
and a tactic. We discuss the importance of movement and what
movement means as it pertains to survival in the active shooter
scenario. We follow that with a discussion on leadership and
being prepared for potential threats. The eight-hour class has
a segment on radio communication and a practical exercise as well.
