Which pressure point is located about three inches from the base of the neck?

The Brachial Plexus Origin is referenced in this context as the pressure point located about three inches from the base of the neck. This area is significant because it is where the network of nerves responsible for innervating the shoulder and upper limb structures can be accessed. Applying pressure to this point can create a level of discomfort or distraction, which can be beneficial in defensive tactics situations, allowing for control over an opponent.

This tactical application derives from an understanding of the anatomy and function of the brachial plexus. Proper knowledge of where this pressure point is located allows a practitioner to effectively implement techniques that can incapacitate or control an adversary without causing significant injury. Understanding this point within the context of defensive tactics can greatly improve an individual's ability to handle confrontational situations effectively.
