best way to knock someone out

[iwariori3]

how is the best,fastest way to knock out someone?? (staelth) :roll:

[Jago]

define stealth, what for? why do you need it?
Chloroform.

Blackjack, if you have the advantage of surprise.

[Steve_TPF]

The fastest way, if you have good technique, is to punch them in the jaw. It's not the most reliable method though. The punch must be forceful and land cleanly.
If you have the advantage of approaching from behind you could choke them unconcious with a sleeper hold. This is probably safer, but takes longer.

What is it exactly about a clean punch to the jaw that knocks someone out? Does the mind just shut down out of shock, or is it something else?

[Steve_TPF]

Basicaly. The brain actually bounces off the skull, the shock to the nervous system overloads it, and the brain shuts down. Hitting the jaw gives the best chance of a knockout. I believe this is because it transfers the impact back to the base of the skull and brainstem.

[scorpz911]

Rear Naked Choke, should only take about 6 seconds when you do it properly.

i heard the jaw punch fucks with some fluid in your ear that has to do withyour balance and your legs buckle

[napalmiscool]

Your legs buckle because you lose consciousness. Two things can happen when your jaw is hit. The first is the immediate transfer of shock from the mandible to the brain stem shutting down the CNS. ( causing your voluntary actions to stop aka knees buckle). Autonomic functions resume almost immediately,( victim begins to snore or gasp for air). The second effect a strong punch to the jaw is disturbing the mandibular nerve to the point where it relays incorrect signals to the CNS. This causes the nerve to send too much blood to the digestive system and there for the brain does not receive sufficient amounts of blood.

Btw Jag, Chloroform does not work like it does in the movies. Large ( semi lethal) amounts would have to be used to "knock out" the person. The effects are not immediate either, taking away from the "stealth" factor.

The bottom-line is that knocking some one out is dangerous and can cause serious damage, the "rear naked choke" as mentioned above is probably your best bet as far as safety, stealth, and effectiveness go. It cuts off the windpipe rendering them unable to talk, yell, or breathe, and it closes the main blood flow to and from the brain. This can knock them out almost instantly if their blood pressure spikes, its the body’s natural response to fix that. If that doesn’t work out for you just clench it until they are limp.

[Steve_TPF]

Thanks for the clarification napalm.
You're right about the cloroform, it takes a good lungful to put someone down and they won't breath it willingly because it's obviously a noxious chemical. If you are strong enough to hold the pad over their mouth long enough then you could easily apply a choke hold. Safer and more effective.

[headcase]

Some of my friends are pretty handy thai boxers and even their chokes aren't bullet-proof. If you get a hand jammed between your neck and their arm then they have to release you. Not the best outcome if you've just tried to choke someone. I'd go with the chloroform. Everyone has to breathe it in eventually and the struggle of trying to get it off will speed that up.

[YoungHypnotiq]

i like a good old fashioned hook, uppercut, overhand, haymaker, or straight. all these to the jaw or temples or chin should knock the guy out. if you want stealth a pipe to the back of the head should work . or just give em a haymaker or overhand to the back of the skull. thats what I would do.

[headcase]

I wouldn't rely on that. Last weekend, I got a clean punch in the jaw while I was looking the other way. Without wanting to talk myself up (although I am a demi-god) it didn't even put me off balance, and I was after a good bit of alcohol at this stage. The other guy was hammered too, but he was still a pretty big guy.

[YoungHypnotiq]

obviously he didnt know how to punch that well.

[M. Aronnax]

I've found that if you hit a chap with your car they go out cold... j/k. but i'm sure that would work as well.

Hey don't blame me, i've never used it :wink: glad you cleared it up tho

[napalmiscool]

hahah no worries jag nothing personal at all, just dont want any one to A kill someone( always bad news) or B try to knock someone out and then get knocked out in return... that is just no fun haha

[headcase]

Whether or not the person is knocked out isn't crucial. after a few lungfuls of chloroform they will be in no state to put up a fight. Hold it over them until they stop fighting and you're sorted.

[M. Aronnax]

hear, hear. I can vouch for the point Mr. headcase is making. Could you not just hold the chap up with a knife at which point he may not even attempt resistance to your chloroform? (i don't know what situation you're going into so that may not be a suitable COA). By the by, from where does one obtain said, "chloroform"?

[Jago]

from memory: sodium hypochlorite + acetone. Decomposes into phosgene, so be careful.
As always, correct me if im wrong.

[Steve_TPF]

Try this if you're still keen on chlorofprm.
Instead of holding a pad over their mouth with your hand, soak the arm of your shirt, then apply a choke hold. The grip is much more secure, and any air he does get is going to be loaded with chloroform. Best of both worlds.

A punch or blunt instrument is still faster though.

[M. Aronnax]

I'm no chemist... i probably should be though. I guess you'd have to know what your doing... I don't even know where to get that stuff.

[napalmiscool]

nice idea steve, best of both worlds. Make sure to have another shirt of somthing handy... wouldnt want to make yourself woosey.

Jag is right, it breaks down into phosgene, in the liver. Like chlorine gas, the Cl in phosgene reacts with the water in your lungs( well all of your body, but the most dangerous is your lungs) causing your lungs to swell and retain water to help repair the damage, but it usually ends up just drowning you in your own fluids. This is some quick info I grabbed from wikipedia :This highly toxic gas gained infamy as a chemical weapon during World War I, Concentrations below 1 ppm may be harmful,Decomposes to further toxic compounds in the presence of water." Side note, whats the body.. like 80% water?

edit:About 70% of the fat free mass of the human body is made of water.

[Jago]

It breaks down over time too if i remember correctly. Chloroform is also carcinogenic.

[napalmiscool]

hahahha after you knock them out with the chloroform you should leave a note that says " sorry for giving you cancer, my bad"

My bro, a petty officer in the U.S. Coast Guard, and soon to be in the first Spec. Ops. division of the Coast Guard, showed me some hand to hand stuff. BTW, he related to me that the Coast Guard Basic Training is second only to the USMC in intensity etc. He first showed me that with a fist or balled hand, preferrably both, strike with a lot of carry through to the side of the neck under the ears. Two major arteries to the brain run there, and you can make someone quite instantly pass out without any more moves. He said that if you use the 'knife-edge' hand technique, you could knock out a disk of the spine and cause semi to full lethal damage, which isn't always what you want to do. He also showed me a compliance grip that basically you get your middle and pointer finger in the eye socket, and thumb deeply hooked under/in the jaw bone. Also, he said a straight shot to the bread basket is a standard effective strike. Another compliance hold is to basically take someone's hand, your palm to the back of the persons hand with your fingers reaching around to their palm, and turning/twisting it like there's no tomorrow will make a person have to stop what they're doing and deal with the pain and their inability to manuever.
A friend showed me his basic go-to technique of stomping on your opponents foot, 'sticking it' basically, and either punching in any desired way, or simply pushing them back while their foot is immobilized and they lose their balance and fall back.
Obviously these things need a some practice to be effective.

Does Anybody know approximaty how much chloroform is enough to knock out a person under a minute
i got 2 pounds of chloroform in my dad's lab. I stole half a pound from that. I want to sedate my uncle joe. He is really a pain in the ass.

You can't. I've read experiences of people who've used Chloroform to sedate and from what I've read it takes at least a minute to kick in.

[fightforcash]

1 word rohypnol lol but in all seriousness its pretty effective ask my victims lol

[bloodlusta]

There is no sure fire way to knock someone out. Sometimes you can deliver a massive hit and they won't go down, other times a not very power blow can put them down. I have had a cricket bat taken to my head and not been knocked out (but I was throwing up for an hour), but one time me and a mate were mucking around and he knocked me out with a light hit to the head.

However a strong open hand clap to both ears at the same time will render someone unable to fight and will ground them as it will burst their ear drums. If you follow this through with a head stamp to the temple they should be knocked out
