Where should you use a brachial stun for maximum effect?

Using a brachial stun to the side of the neck is effective because this area is vital for both the nervous and vascular systems. The brachial plexus, which is a network of nerves near the side of the neck, can be disrupted by a targeted strike. This disruption can cause temporary incapacitation, making it an advantageous location for law enforcement personnel to target in self-defense situations. The area is not heavily protected by muscle or bone, allowing for a more effective impact that can stun an opponent.

In contrast, the other locations such as the forearm, back of the head, and chest area do not offer the same level of effectiveness for a brachial stun. The forearm may not have as pronounced an effect since it doesn't directly target critical nerves or structures. The back of the head is often more resistant to such strikes due to the skull's protective structure, while the chest area does not contain the same vital nerve points that would incapacitate an individual quickly. Thus, striking to the side of the neck maximizes the potential for the desired outcome in a self-defense scenario.
