The job of your personal protection instructor is to make you an escape artist. The better trained you are the smoother your escape. You will slip out of conflicts without engagement. Which is the culmination of a well evaluated situation and it’s appropriate reaction. If you have to engage (“Have to” is key here), it will probably be because you unwittingly painted yourself in a situational “corner” (Zigged instead of zagged) and you have to make your evasion, a forceful one.
Still, no matter how forceful it is, from a hard shove to caving in someone skull, it should still be an evasion (part of an escape plan). Therefore whatever forceful means you use (tools), they need to be applied toward bringing yourself to safety. Nothing else. When do you stop “mauling”? When you know the attacker has been made “safe” for you and/or cannot prevent you from getting yourself to safety. Every time you engage, you increase the number of variables, slow down your exit, give the opportunity for bystanders to get involved and other headaches.
As oppose to a jailbreaker, you have, too often, to formulate a coherent strategy to bail out on the spot with a minimum of info acquired almost on the moment. A good thing to do, when you enter a location that could be unsafe… scope before, take a tactical look, file in your brain where the bottlenecks are, the ways out in order to speed your ability to decide upon an evasive scenario. I call that Quick tactical mapping. If you have to engage, you will facilitate your exit. I’ve seen some guys win fights in spectacular fashion and doing it in a way that made them jump from the frying pan into the fire because of the fact they fought without factoring in where it could end. Example? Engaged at the door, ended in the coatroom (4 x 12) back against the wall with 5 of the guy’s friends coming in with bottles and one with a pool cue. Did not end well for a guy who actually beat up his man.
Counter ambush and evasion skills. Starts with that.
