Brachial strikes are very dangerous to practice on people. "Bob" torso punching bags are a better way to work on the technique.
There are too many videos where the strike is demonstrated on people to list, and not enough of them warn people about it. Take a look at these two Marines, (youtu.be) for example.
These are not Brachial strikes, these are to the side of the neck. And, cutting off the carotid for 100th of a second is not going to knock anyone out. A Brachial strike would be straight on to the front of the neck with say the heal of your hand. And yes, very very dangerous.
Edit: I don't know if the marine video is real but it sure looks good.
Ahhh.... Duh,, my bad, I was thinking Trachea !!! lol, Thank you for the correction!!
Here's a good video (youtu.be) that talks more about it.
