Subduing an opponent in an emergency situation requires careful and decisive action. Here are some strategies and suggestions, but remember that ensuring your own safety and the safety of others always comes first: 1. **Analyze the situation calmly**: Quickly assess the nature and extent of the threat. Determine whether you can calm the opponent with words or whether further measures are needed. 2. **Keep your distance**: When possible, keep a safe distance to allow enough time and space to react. 3. **Use non-lethal means**: - **Verbal de-escalation**: Try to ease the tension through dialogue. - **Object protection**: Use objects around you (such as chairs, tables) as shields to prevent the opponent from approaching. - **Non-lethal weapons**: If legal and possible, use non-lethal tools such as pepper spray. 4. **Seek help**: Try to notify others or call the police to get professional assistance. 5. **Learn self-defense techniques**: - **Basic fighting skills**: Master basic defense and subjugation techniques, such as Aikido, Judo or Brazilian Jiu-Jitsu. - **Key parts**: Understand the key vulnerable parts of the human body, such as eyes, knees, etc., and defend yourself when necessary. 6. **Adapt to local conditions**: Use environmental advantages, such as terrain heights, obstacles, etc. to help you control the situation. 7. **Stay alert**: After subduing the opponent, stay alert to prevent the opponent from counterattacking or other threats. At any time, it is the wisest choice to avoid unnecessary physical conflicts, especially when there may be legal consequences and risks of personal injury. Taking formal self-defense training courses can provide you with more effective skills and strategies.
