Which operation is considered the first line of defense for Border Patrol?

Linewatch Operations are considered the first line of defense for Border Patrol because they involve active surveillance and monitoring of specific areas along the border where illegal entry is most likely to occur. These operations are crucial for the identification and apprehension of individuals attempting to cross the border unlawfully. They typically take place in remote areas, allowing agents to proactively deter illegal activities through direct interaction and observation.

While checkpoints, surveillance, and roadside patrols are important components of Border Patrol operations, they generally serve as secondary measures that support the primary mission of preventing illegal immigration and drug smuggling. Checkpoints tend to be fixed locations where vehicles are stopped for inspection, surveillance can be done from various locations to monitor activities, and roadside patrols primarily focus on patrolling vehicular traffic to enforce laws and provide assistance. Linewatch Operations are characterized by their proactive and tactical approach, making them fundamental in the overall border security strategy.
