GEM...
read an earlier iteration of that idea (study, I found at the Uni library actually), the fact that an 'average' gun toting criminal has MORE trigger time, both in shoot outs, and back alley 'target practice' shooting rats and cans, than an average patrol officer.
When I left the army, my unit went from the usual 2x a year qualification, to much more realistic 'run and gun' type iterations, such as getting from prone to firing on the move, around building corners, etc. And that was for the support troops
What can you learn, first, how much you don't know
how much you are not practicing
and what counts.
Had a PA, prior SF Medic, he said, SF isn't really that much better than regular army, they just do fewer, different things, and practice A LOT more. And they learn tricks, practice things that honestly are not addressed in RA, stuff like, magazine changes, the difference between what he showed us, in magazine changes, was how he'd learned his gear, blindfolded, not super fast, just very SURE and SMOOTH. Instead of a talk though, or just 'change magazine' it was , blind fold on, what move are you making, why, next move, why...
The point of training is in the outcome
to get you past the 'OH ****' moment, which is where many people freeze
Look up Heuristics and training, many people freeze because, much like a computer, unexpected input isn't being processed, there's no 'category' for 'getting sucker punched' or 'mugged' so they are stuck going 'uh uh uh'
Once they identify the 'situation' they can think of outcomes, but they don't KNOW, don't have a standard operating procedure for it. Punch a martial artist, and they'll comeback fighting, or block the blow if they see it coming.
On the mag changes, why blindfolded, because, it trained you NOT to look, to trust your hands and sense of feel to find the mag and put in the rifle.
To quote Fred.... Mindset, Skillset, Equipment, in that order.
Why pay the money for the classes, because the kinetic sense of how it "should be" isn't something you can get off the internet or a video, nor is the professional eye of a trainer, explaining what you ARE doing, and how you SHOULD be doing it.
Sorry for the long post.
