'Road Block' is done in terrorist affected areas. Which of the following principles should be followed in it ?

1. It should make it difficult for the terrorists to turn back

2. Adequate troops should be kept in the open

3. Manning of road block should be done as per traffic movement

4. Proper communication be set up, audible to all nearby personnel

Select the correct answer using the code given below :

The establishment of a 'Road Block' (Naka) in terrorist-affected areas follows strict tactical principles to ensure the safety of security forces and the effectiveness of the operation:

• Statement 1 is correct: A road block should be strategically located (e.g., after a sharp bend or near a narrow bridge) so that a vehicle driver sees it only when it is too late to turn back or escape.
• Statement 2 is incorrect: Troops should never be kept in the open as they become 'sitting ducks' for terrorists. They must be positioned in fortified, concealed, or protected spots (like sangars or bunkers) to provide cover to the searching party.
• Statement 3 is correct: The manning and scale of the road block should be adjusted based on traffic volume to ensure thorough checking without creating excessive bottlenecks that could be exploited.
• Statement 4 is incorrect: Communication should be secure and discrete (e.g., via radio/signals). Making it audible to all nearby personnel (including suspects) would compromise tactical instructions and operational security.
