Your attack back attitude is one of the most important aspects to surviving an attack. In the book
Real World Self-Defense, which I recommend, Jerry VanCook states:
"Col. Rex Applegate, an American Office of Strategic Services (OSS) command officer during World War II who was closely associated with Fairbairn and Sykes, explains this in his book
Kill or Get Killed when he speaks of mental balance: 'The most basic fundamental of all is that of balance. Mental balance, or stability, is a state of mind that is necessary before physical balance can be achieved.' My interpretation of what the colonel calls 'mental balance' here is that in a violent self-defense situation we must each, in a sense, become two people. One of 'us' must be subjective, letting our natural fear and outrage provide the fuel for our defense. But the other one of 'us,' the objective 'us,' must keep that fear and outrage from going wild and spending itself on unproductive action. All of our efforts must remain focused on our ultimate goal - survival. And if we can break the mental balance of our opponent while retaining our own duality, we gain a tremendous advantage."
I had the oportunity to meet with Col. Applegate before he passed away, and I also highly recommend his books. This advice from the colonel and Jerry VanCook is something you should consider when mentally preparing to attack back if that day comes. Your attitude and "mental balance" will play an important role in being able to attack back and survice in a violent encounter.
Stay Safe!
