What role does the backup officer play at a checkpoint?

The role of the backup officer at a checkpoint is primarily to provide assistance to the primary officer. This can include observing interactions, offering support during vehicle inspections, and ensuring general safety while the primary officer is engaged. The presence of a backup officer allows for increased efficiency by enabling the primary officer to focus on their duties without the added stress of potential threats or complications that may arise. Additionally, the backup officer can step in if any situation escalates, therefore enhancing the overall security and effectiveness of the checkpoint operations.
