185 miles complete. They’ll have to be motivated to climb those barriers.
Sure they can dig tunnels and fly drones, but the barrier makes life way harder for the bad guys.
“Sure they can dig tunnels and fly drones, but the barrier makes life way harder for the bad guys.”
By design, it makes it much harder for tunnels and drones as well.
Most of the old barrier required no tunneling (vehicle barriers), or shallow digs that children could do (just a few feet long, about a foot deep). The bollards require going six to eight feet down to get under the foundation, and have cleared areas on both sides, that must be tunneled under to conceal entrances, exits and digging activity. In some areas, 150 feet is cleared on the South side, and on the North side, it is cleared to the Northern shoulder of the patrol road. Such long and deep tunnels are simply far beyond almost all individuals’ ability, and are life-threateningly dangerous to construct.
Seismic (vibration) sensors can detect tunneling activity, and vehicle towed or airborne ground penetrating radar can detect tunnels themselves.
Radars are being deployed to detect drones, and countermeasure systems already exist, that have allowed Border Patrol to take flight control of cartel drones, and land them where they want.
