The rookie is “obeying” the commands he so often got at basic; also the TEAM training: when one goes down, all go down.

I remember one recruit in the rifle shoot house that did a nice job of clearing all the rooms and hitting the targets high center mass…one of which was UC with a clean 223 hole through the badge round his neck.

I suspect “training scar” issues like this occur more from novice skill levels rather than learning a “bad” habit. When academy/basic training remains the totality of formal learning a person has, they’re more likely to repeat such things because it’s the only response available in a rather limited playbook, especially when there is little to no history of performing under pressure where the results truly matter to them.

Example. We shot a series of surprise courses at CAFSAC in the shoot houses at Connaught, Ottawa. Despite shooting these after the fixed, square range courses (the sort that allegedly cause “training scars”) not a single competitor displayed any such mistake. None of the range officers reported anyone inadvertently remaining flat footed when they should have been moving, failing to use cover, unloading before finding and engaging targets, etc. It’s almost as if being more skillful and being used to performing at a higher level while under pressure where the results matter helps people perform better while under pressure. And they could perform appropriately according to the given context/situation at hand. Amazing!

From John Tate:
You speak of a “limited playbook.” My phrase is tool box/tool bag. And I fully agree.

Once upon a time, LONG, LONG ago, I played guitar and 5-string banjo. The fingering is vastly different. But one learns to change “playbooks.”

Your square range vs. shoot house example illustrates identical adaptation to the environment.

The one quasi-counterexample I would give is a person reacting to an instantaneous and severe stimulus where either instinct or habit takes over before conscious thought. I liken these to “brake pedal moments.” BUT – as you said, “[B]eing more skillful and being used to performing at a higher level while under pressure where the results matter helps people perform better while under pressure. And they could perform appropriately according to the given context/situation at hand.”

All of which goes back to the “train to die” model of only shooting the standard, flat-foot, stationary target qual course.
