Final answer:
Soldiers on extra duty may perform CQ or access control guard in a single night.
Step-by-step explanation:
The statement that soldiers on extra duty may also perform CQ or access control guard in a single night is true.
In the context of military operations, CQ stands for Charge of Quarters, which refers to a duty where a soldier is responsible for the security and safety of a specific area or facility during a designated period. Access control guard, on the other hand, involves regulating entry and exit points to ensure authorized personnel only access restricted areas. Soldiers on extra duty may be assigned to perform both of these tasks in a single night depending on the circumstances and requirements.
