The video discusses the necessity of knocking someone out in a self-defense situation, particularly when facing multiple attackers. The instructor shares three knockout moves inspired by Aikido techniques.
The first technique involves a chop to the side of the neck, targeting the tendons and nerves. The second technique is a palm strike to the chin, as demonstrated by a female security guard who took down an aggressive individual.
The third technique involves a combination of blocking an attacker's hand, striking their neck, and pulling their head down. This technique was used by the instructor in a real-life situation when he was working as a security guard.
