Final answer:
Sergeant Wilson may leave her assigned post under certain conditions such as emergencies, explicit orders or shift changes.
Step-by-step explanation:
In a military setting, a roadblock is set up to prevent unauthorized access or control the flow of traffic. Sergeant Wilson, as an assigned personnel, should remain at her post until given permission to leave. However, there are certain conditions under which Sergeant Wilson may leave her assigned post, such as:
- If there is a higher priority emergency or mission-critical task that requires her immediate attention.
- If she receives explicit orders from her commanding officer to vacate the post.
- If her shift is over and she is properly relieved by another personnel.
It is important to note that leaving one's assigned post without proper authorization can have serious consequences and should not be done without valid reasons.
