### Technique Name: Rear Naked Choke The Rear Naked Choke (RNC) is a fundamental submission technique primarily utilized in Brazilian Jiu-Jitsu, mixed martial arts (MMA), and self-defense. It is renowned for its effectiveness and efficiency in causing an opponent to submit or lose consciousness when applied correctly. ### Japanese Name: Mata Leão (although not strictly a Japanese name, it's commonly used due to its popularity in Brazilian Jiu-Jitsu which has Japanese roots) ### Position: - **Back Mount** ### Top or Bottom: - **Top** --- ### Step-by-Step Instructions: 1. **Achieve Back Control:** - Begin by securing back control on your opponent. - Ensure you have your hooks in, which involves placing your legs around the opponent's waist, with your feet hooked inside their thighs for control. - Hold onto your opponent's upper body using an over-under body lock (one arm wrapping over the shoulder and under the armpit, and the other arm under the other armpit and over the shoulder). 2. **Position Your Arms:** - Choose your dominant arm to wrap around the neck of your opponent. - Slide your dominant arm's bicep under one side of their neck so that the crook of your elbow is beneath their chin. - Ensure your dominant hand goes behind the opponent's head while your other hand remains in front. 3. **Secure the Choke:** - With your non-dominant hand, grab your dominant arm's bicep. - Use your free hand (non-dominant arm) to gently place or cup the back of the opponent's head. This hand orientates as a support to seal the grip. 4. **Squeeze and Adjust:** - Apply pressure by squeezing your elbows together while pushing the opponent's head forward. - Tuck your chin to your opponent's shoulder to provide protection and ensure tight control. - It is crucial to maintain a calm and steady squeeze to exert a controlled pressure on the carotid arteries, contributing to the choke's efficiency. 5. **Finish the Choke:** - Maintain pressure while simultaneously arching your back slightly to increase the choke's effectiveness. - The aim is to cut off circulation to your opponent's brain, leading to a swift, safe, and humane submission. ### Notes and Tips: - Always practice the technique safely and under supervision, ensuring the opponent has no injuries. - Be conscious of the opponent's willingness to tap in training; safety should always be a priority. - Focus on technique, ensuring each step is performed with precision and control. - The move can be transitioned into or adapted with technique variations, often seen in competitive scenarios and grappling exchanges.​ The RNC is an essential technique that every practitioner should master, capable of effectively ending a confrontation in seconds. Remember always to employ proper form and safety when practicing or applying in contests.
