It seems you are trained in martial arts because during my training the first attack that i was taught was to hit in the groin area and keep hitting otherwise too till the attacker falls down. If my life is in danger then literally gouge his eyes out, blind him in one eye or both. I may or may not be able to defend myself in court if i kill him and but i have been taught the levels and lengths of defence I can go to considering the intensity of provocation I face.
If i am defending a third party (my family or a client) and all else fails, and lives are in danger, then I would go for the neck break or choke to kill. The use of gun is similar, injure by firing at leg or arm, or kill by aiming at heart or forehead, depends upon situation.
However, KM teaches third party protection which body guards use to protect clients and get them out of danger and into safety. For a private citizen, it helps in saving family, parents, kids etc.
About second nature, yes. I give a break in my KM lessons because at times i feel my second nature of awareness is taking over me. I start to sense people walking behind me, people making eye contact with me while i walk on streets, the way cars pass by me, the way people look at me, the things they are holding in their hands, people wearing hoodies, people hiding hands in pickets, i start to notice pockets even. i start to notice peoples face expressions, their eyes, their way of walking, if they are walking nervously, if they ware walking aggressively, if they are walking too cautiously themselves. KM has instilled in me to walk in the direction where cars are coming in my opposite direction, rather than walk in direction where cars are passing by me from behind. Every new building i enter, its become second nature to see the exits in that room instantly, the windows, doors, exit signs etc.
Above is the awareness factor i was talking about in earlier post.
There was a thread made a few years ago on side arms for self defence, and the thread holds good material on hand guns, security, awareness etc.
There has been excellent material posted by
@RescueRanger . His threads hold significant subject matter and information on the topic of security.
I hate to admit it. I have been beaten in sparring and during lessons through techniques by 5 feet tall girl whereas my height is 6 feet. No wonder i found more women than men training in KM classes. On the contrary I have been trained in techniques to subdue a person more taller and more heavier than me so yes its KM is good to go for girls.
There have been classes specially designed for women taught by women for reals life scenarios, in house, in car, in streets, in markets, at public places. I obviously didnt attend those classes but i know they are provided as i have seen in training centre.
In my earlier post, I posted a link of a woman Munazzah who learnt only 9 techniques to protect herself, there are many many more techniques and many more scenarios that can be learnt in KM as KM revolves around real life scenarios, not the 1,2,3 punch kick elbow taught in other Karate and martial arts although yes BJJ is very helpful and there have been classes of grappling taught in KM to tackle an opponent who is trained in BJJ.
Bully Kutta (BK) is basically a fighting breed, its size is intimidating.
A breed called Belgian shepherd dog BSD (primarily Malinois) has been specifically bred for purpose of protection work - protecting person and property. Its size is smaller than of a German shepherd dog (GSD) but it can jump higher than a GSD, it has more energy than a GSD, it has more prey drive and it can be termed as a "GSD on steroids". Its coat is smoother and can stand heat of the desert during day while some working breeds are more active at night in cool weather. A BSD can easily fit into a car such as can be seen in police cars, can leap in and out of car windows, can climb ladders even.
I can talk for long about GSD or BSD, but there are thousands of videos on youtube about their effectiveness in protection work.
