Didn't say that either,
Some situation obviously require an instantaneous reaction. A battlefield would seem to be one. Training can "inform" that reaction, or so I have been told.
I was not trained to fight. I served, I did my job well. Not that many enlisted navy jobs actually involve personally fighting in a combat situation. That is just what it is.
As for a personal decision to fight or flee, I was trying to say that the thing is to not just always react to one's "feelings" in every situation, but that hopefully some thought goes into choosing the appropriate and necessary response. Training can inform that process also, or so I have been told. Told by a cousin who taught at Quantico, and a half dozen other LEO's in the family. Universally, they stressed the training and the necessity to evaluate before acting, and that what eventually became "second nature" or a "natural response" was in reality the result of training and mental conditioning.
