What action can a soldier take if someone gains unauthorized access?

A soldier has a responsibility to maintain security and ensure that unauthorized access is addressed appropriately. The correct action in this scenario involves temporarily detaining the individual who has gained unauthorized access. This allows the soldier to assess the situation, gather additional information, and prevent any potential harm or further breaches while ensuring that proper procedures are followed to manage the threat.

This action is based on the principle of maintaining security and safety in a potentially hazardous situation. By temporarily detaining the individual, the soldier can prevent them from causing any damage, gaining further access, or escalating the situation before higher authorities can take over and handle the matter appropriately.

The other options do not provide immediate or effective responses to the situation. Ignoring it is not an option as it could lead to security breaches or unsafe situations. Calling for reinforcements may take time and doesn’t help with the immediate threat posed by the unauthorized individual. Escalating the issue to higher authority is crucial after assessing the situation, but immediate action is required to ensure control over the unauthorized access. Therefore, temporarily detaining the individual is the most appropriate course of action.
