In checkpoint operations, which duty is considered the first line of contact?

In checkpoint operations, the duty that is considered the first line of contact is the Primary Agent. This individual is responsible for the initial assessment of vehicles and individuals entering the checkpoint. They conduct primary inspections to determine whether further action or investigation is necessary.

The Primary Agent engages with travelers directly, asking questions and observing behavior, which forms the foundation of the checkpoint's operational effectiveness. Their role is crucial in making initial determinations about potential threats or immigration status based on a combination of visual cues, verbal interactions, and sometimes preliminary checks.

In contrast, the Backup Agent typically provides support and assists the Primary Agent, but does not take the lead in initial contact. Similarly, the Rover Agent may move between lanes or areas of the checkpoint to support agents as needed, while the Secondary Agent typically gets involved only after issues are identified during the primary inspection, such as when further questioning or inspection of a vehicle is warranted. Thus, the Primary Agent is central to the checkpoint's workflow and the first interaction for any individuals approaching the checkpoint.
