It's called Krav Maga. Best damn martial art in the world. Look it up. The best thing about it? It is 100% compatible with all other martial arts. How? It has no set moves. Just a psychological mindset. The "No quarter" mindset. If you're defending yourself, the other guy should NEVER have the ability to even THINK about attacking you again.
I've seen several Krav Maga demos, and they don't impress me as much as, say, watching Boxing or Wrestling. The demo givers had a few simple disarms, which was good, but didn't follow up well. The link I gave had some notes on that. Not to say that this couldn't be a perfectly valid martial art. I just don't see it in my exposure. I'm sure a good teacher could convince me otherwise--if you know of one, put me in touch.
I'm not sure about your "no set moves" concept. Do you mean that they have no closed syllabus, or that they have no actual taught moveset? Or something else entirely?
As for martial arts, I'd like to train in boxing, stand-up wrestling, historical western martial arts, and run some knifing scenarios.
How is that different from other martial arts demos? You have an asshole trying to make money by impressing you with set moves. REAL Krav Maga is what they teach in the IDF. The Israeli army.
There, you get to learn adaptive combat and improved weapon use. In Israel, the use of weapons is legal in self defense. Seriously. If you grab a chair and defend yourself with it, it's self defense.
By no set moves, I mean there are no specific motions or styles. It's just a mentality. Like Parkour is just a mentality/philosophy for how you use free running.
It's not WHAT you do. It's HOW you do it. The key word? No quarter. Okay, two words. Sue me.
No quarter pretty much means no mercy. Disarming is just the first step. But the key goal is making the gun point away from you or anyone else for as little as one second. During that time, you can easily daze him and stun him. While he's stunned, just disarm the weapon normally whilst still attacking a region like his face or his crotch.
Back to self defense law, IIRC, dirty fighting is not illegal if used in self defense. You come charging at me and I kill all your potential future children? You're guilty of assault and I'm a free man. (This is referring to Israel. I have no idea how pansy the self defense laws in the USA are.)
Back to Krav Maga. Krav Maga literally means "Contact combat" in Hebrew. But a proper translation would be "Close combat"
The mentality is this: There's a guy there and he's attacking me. How can I disarm him in the fastest and most painful way possible, then escape while he is unable to chase me or gun me down?
The answer? Use a gun And if that don't work? Use more gun.
-Engineer.
The real answer? Cave his face in, smash his nads and break his weapon hand. All within 3 seconds or less.
"But Yanlin! I'm a pussyfist! I don't like fighting!"
Well then. You stun him. A quick jab to the back of the head or the neck, maybe a kick in the balls while shunting away his weapon arm and if he has a gun, stealing the actual gun so he can't shoot you with it. Or "reloading" the gun by making the gun drop the magazine. Most pistols allow you to do that. By the time he finishes picking it up and reloading, you'll be far away.
Now back to the mentality. In Krav Maga, you can utilize ANY martial art. But the "default" form of Krav Maga is your natural human instinct. YOU know where humans are weak. ATTACK THOSE WEAK SPOTS! For massive damage! Turn him into a giant enemy crab!
You don't need to know any complex movements as long as he doesn't!
