Mehh IMO you don't need to be trained to operator level what you really need in my opinion is Luck muscle memory & consistency with the basics, clear holster and accurately hit targets center mass/fail to stop in a decent time with the slow is smooth, smooth is fast. Honestly in a fight you will likely revert to gross motor functions witch is where muscle memory comes in.
What's crazy is the guys who do operate at an alpha operator level only really practice the basics and master the fundamentals.
Keller told us before a deploy all he would do for months leading up are standard ready up drills on 3 inch and 6 inch circles from 10 to 15 yards. And he rarely shot on the range for more than an hour a day, due to fatigue and training scars then developing. All the hopping over cars bs, shooting upside down with one arm behind your back, and sprint before shooting stuff was just that...stuff. At the end of the day a shot, no matter the situation or position will come down to sight alignment, sight picture, trigger squeeze.
And it's all true. We do very little steel work in his classes and constant reps of ready up drills and offhand shooting. Barely any moving and shooting.
But by the end of the 2nd day everyone in the class had their time and accuracy improve in the moving and shooting steel drills by at least 5 sometimes 10 seconds. And the weather the 2nd day compared to the first was pure ass. Thunderstorms all day, rain and fog.
