The strategy for winning a defensive gunfight is converting disadvantage to advantage.
Let’s clarify what we mean by defensive combative firearms training.
Because you are not the one instigating the confrontation, you will initially be at a disadvantage and in a reactionary and defensive state because you are behind in what John Boyd called the decision making process or the “OODA Loop”.
Conversely, because your adversary is selecting the time, palace, conditions, and weaponry for the confrontation – he will initially start with the initiative as the causal factor in your situation because he has already completed may OODA Loops before you ever even knew of him or his intent.
While starting in a reactive state is an initial disadvantage; proper training can teach you how to convert this initial reactive and disadvantageous situation to your advantage and to the disadvantage of your adversary.
Solid training programs can teach you how to react in a manner that will cause your adversary to react to your actions, and exploiting this initial success can allow you to then wrestle the initiative away from your adversary and then keep him in a reactive state so you can end the with a more favorable outcome for yourself.
The key here is for you to become the causal factor to your adversaries plan for you, and thereby placing him in a disadvantageous reactive state, and the more solid your skills are, the easier it will be for you.
Obviously, converting the initial disadvantage to advantage is key, and this key does have a price, and that price is effort in training.
