Introduction to National Defense and Public Safety for Grade 10

Understanding the fundamentals of national defense and public safety is essential for every Vietnamese high‑school student. This course expands on the key concepts tested in the quiz "Ôn tập Giáo dục quốc phòng và an ninh lớp 10" and provides clear explanations, real‑world examples, and practical advice. By the end of the lesson, learners will be able to identify the components of Vietnam’s armed forces, recognize the role of drug precursors, know how to respond to traffic signals, and apply basic first‑aid techniques.

1. The People’s Armed Forces of Vietnam

Vietnam’s security architecture is built on three main components that together form the People’s Armed Forces. These forces operate under the principle of “people’s war” and are tasked with defending sovereignty, maintaining internal order, and supporting civil development.

• Quân đội Nhân dân (People’s Army): The primary military organization responsible for external defense, disaster relief, and international peacekeeping.
• Công an Nhân dân (People’s Police): The civilian police force that ensures public order, combats crime, and protects citizens’ rights.
• Dân quân Tự vệ (People’s Self‑Defense Force): A volunteer militia that assists in local security, emergency response, and community policing.

Other units such as the Cảnh sát biển (Coast Guard) are specialized branches within the broader structure, but they do not replace any of the three core components.

2. Drug Precursors: The Starting Point of Illicit Production

In the fight against narcotics, understanding the role of tiền chất ma túy (drug precursors) is crucial. These chemicals are the essential raw materials used in the manufacturing stage of drug production.

• They are combined, processed, or transformed to create illicit substances such as methamphetamine, heroin, or synthetic cannabinoids.
• Controlling the distribution of precursors helps law‑enforcement agencies disrupt the supply chain before the final product reaches the market.

Other activities—such as trafficking, storage, or sale—are downstream actions that rely on the existence of the precursor‑derived drug.

3. Reporting Suspicious Drug Activity

When you suspect illegal drug transport or trade, the safest and most effective response is to report the incident anonymously to the nearest police authority. This approach protects the community and ensures that trained professionals handle the situation.

• Do not confront suspects directly; this can endanger your safety and compromise investigations.
• Provide clear details: location, description of individuals, vehicle plates, and any observed behavior.
• Use official hotlines or mobile apps designed for confidential reporting.

Remaining silent or creating a public disturbance does not contribute to public safety and may even hinder law‑enforcement efforts.

4. Traffic Signals: Understanding the Red Light

Road safety is a core component of national security. The red traffic light is a universal command that requires drivers and pedestrians to come to a complete stop. This pause allows intersecting traffic to clear the way, reducing the risk of collisions.

• Never interpret a red light as a cue to slow down or turn; those actions are reserved for green or yellow signals under specific conditions.
• Pedestrians should also stop at the curb and wait for the walk signal before crossing.

Compliance with traffic signals not only prevents accidents but also demonstrates respect for the rule of law.

5. Railway Crossing Safety

When approaching a railway crossing where lights, bells, and barriers are active, the correct action is to stop at a safe distance behind the barrier. This distance provides a buffer zone in case a train passes unexpectedly.

• Never attempt to walk or drive close to the barrier to get a better view of the train; visibility can be deceptive.
• Do not cross the tracks until the warning devices have stopped and the barrier is fully lifted.
• Maintain awareness of any additional signals, such as flashing lights or audible alarms.

Following these precautions protects lives and ensures the smooth operation of rail transport.

6. The Core Role of the People’s Police

Among Vietnam’s security institutions, the Công an Nhân dân (People’s Police) serves as the nòng cốt—the backbone—of national security and public order. Their responsibilities include:

• Preventing and investigating crimes, including drug trafficking and violent offenses.
• Maintaining public order during events, protests, and emergencies.
• Cooperating with the military and self‑defense forces to safeguard the nation’s stability.

While the army focuses on external threats and the self‑defense force assists locally, the police are the primary agency interacting with citizens on a daily basis.

7. Basic First‑Aid: Controlling Bleeding

In emergency medicine, the immediate goal of temporary bleeding control is to stop the loss of blood. Rapid hemorrhage management can be the difference between life and death.

• Apply direct pressure with a clean cloth or bandage to the wound.
• If bleeding persists, use a pressure dressing or tourniquet as a last resort.
• While controlling bleeding, simultaneously call for professional medical assistance.

Cleaning the wound or moving the victim to a safe location are important secondary steps, but they should not delay hemorrhage control.

8. First‑Aid: Stabilizing Fractured Bones

When a bone is broken, proper splinting must stabilize both the joint above and the joint below the fracture site. This technique prevents further injury and reduces pain.

• Identify the ends of the broken limb and align them as naturally as possible.
• Place a rigid object (e.g., a wooden board or a rolled newspaper) along the length of the limb, extending beyond the fracture.
• Secure the splint with bandages or cloth strips, ensuring that the joints above and below the break remain immobile.

Improper splinting—such as fixing only one joint—can cause additional damage to surrounding tissues and nerves.

Conclusion

This course has covered eight essential topics that intersect national defense, public safety, and emergency response. Mastery of these concepts not only prepares students for examinations but also equips them with practical knowledge for everyday life. By recognizing the structure of Vietnam’s armed forces, understanding drug‑related risks, obeying traffic and railway signals, respecting the role of the police, and applying basic first‑aid skills, learners contribute to a safer, more resilient society.

Remember to stay informed, act responsibly, and always prioritize the well‑being of your community.
