I totally understand what you’re all saying - and I experienced it a bit when I did the Proving Ground for one of our Live Training Broadcasts 2 years ago.
I couldn’t remember how many shots I had fired or how I got to the door. I do remember snapshots - Kevin’s voice telling me to never turn my back on a loaded gun from before we started, slamming my backside into the exit door so hard as I was retreating and firing that I set off the alarm.
The guy we had playing the attacker totally freaked me out during that scenario. It felt like I was in a real-life horror movie.
