What does the term 'operator on duty' refer to?

The term 'operator on duty' specifically refers to the officer currently controlling operations. This individual is responsible for overseeing and coordinating various activities during their shift, ensuring that all procedures are followed and that law enforcement actions are executed effectively. The operator on duty plays a crucial role in maintaining order and addressing any incidents that arise, making them central to the functioning of the unit at that time.

The other options may refer to related roles within the organization, such as a training supervisor or someone responsible for equipment, but they do not capture the primary responsibilities associated with being the active operator managing operations during their duty period.
