Oh.
Why would anyone need that, apart from military personnel?
Some folks have the mindset to receive training beyond the basics.
Yes you start out with gun safety and basic marksmanship.
Advanced classes teach you everything from survival and hand to hand combat to shooting on the run, force on force shooting techniques, point shooting, speed reloading, footwork, cover techniques, flanking maneuvers and such.
Situational awareness and advance plans of action. It builds confidence and gives you a fighting chance to prevail.
It's not all about guns, a well trained person could survive a deadly confrontation with just a small flashlight or evasive maneuvers. It makes you aware of potential dangers and how to avoid them in the first place. The ability to not become a target for crime as most criminals like to prey on the weak and unprepared.
Some times all the difference in the world is just paying attention, walking with a spring in our step and holding your head high.
With the right training, an old person with an umbrella could whip some serious butt after receiving special instruction.
