What system must you use for conducting travel authorization?

The correct choice is BPETS (Border Patrol Employee Travel System), which is specifically designed for managing travel authorization within Border Patrol operations. Using BPETS ensures that the travel processes align with the agency’s guidelines and regulations while facilitating efficient tracking and documentation of travel requests and approvals. This system provides a standardized method for submitting and processing travel authorizations, ensuring that all necessary information is collected and organized appropriately.

In contrast, the other options do not relate specifically to the travel authorization process in Border Patrol. The DEPARTMENT SYSTEM is more generic and may refer to various functional systems within the department but does not indicate travel-specific use. ELECTRONIC TRAVEL AUTHORIZATION could imply a broader electronic system but is not specifically tied to Border Patrol's requirements or its unique characteristics. The TRAVEL LOG SYSTEM might be relevant to tracking travel but does not encompass the full process of obtaining authorizations for travel, which is critical in the context of Border Patrol operations. Thus, BPETS stands out as the dedicated tool for this task.
