U.S. forces use drones to install concertina wire along southern border

Key Points
  • Joint Task Force–Southern Border is using TRV-150C unmanned aircraft to deliver supplies and help emplace concertina wire and physical barriers along the U.S.-Mexico border
  • The deployment expands the role of autonomous systems beyond surveillance to include border fortification and persistent river monitoring with long-endurance unmanned surface vessels

The United States Joint Task Force–Southern Border (JTF-SB) is expanding the role of autonomous systems along the U.S.-Mexico border, using unmanned aircraft not only for surveillance and resupply, but also to help emplace physical border obstacles, including concertina wire.

The shift turns the southern border into an active operational environment where emerging military systems are being used for both persistent monitoring and physical fortification missions.

At the center of this effort is the Tactical Resupply Unmanned Aircraft System (TRUAS), specifically the TRV-150C, a quadcopter-style unmanned platform fielded by U.S. Marines assigned to JTF-SB across the central and western sectors of the joint operations area. While originally designed as an autonomous cargo drone for last-mile sustainment, the system is now also being used in barrier emplacement missions.

According to the task force, personnel are securing concertina wire to the Tactical Resupply Unmanned Aircraft, allowing the drone to transport and position rolls of razor wire and other barrier materials in terrain that is difficult to access quickly by vehicle or foot patrols. This means the drones are no longer limited to patrol, reconnaissance, or supply functions — they are also being integrated directly into border fortification operations.

The immediate relevance of the development lies in its dual-use operational role. Alongside traditional surveillance and logistics support, unmanned systems are now being used to assist with the installation of physical border obstacles and wire barriers, expanding their contribution to force protection and access denial.

The TRV-150C is designed to be operated by any trained servicemember rather than a dedicated aviation specialist. Its center-of-gravity configuration allows it to carry up to 150 pounds, making it capable of transporting not only supplies such as ammunition, medical kits, and communications equipment, but also rolls of concertina wire and engineering materials needed for rapid emplacement of border obstacles.

This gives border units a tool for quickly establishing or reinforcing barriers in hard-to-reach sectors without exposing personnel for prolonged periods in open terrain. Such use is especially relevant in sectors where access roads are limited or where terrain slows traditional engineering vehicles.

Marine Gunnery Sgt. Abrahim Bosch, operations chief for Combat Logistics Company, JTF-SB, said, “The TRV is a game-changer for the last tactical mile. By putting autonomous resupply directly into the hands of our ground squads, we ensure they remain sustained and mission-ready without waiting on traditional logistics chains.”

That operational concept now extends beyond sustainment. By enabling drones to move and place wire barriers, the system supports a broader hybrid security mission that combines logistics, surveillance, and obstacle emplacement.

Farther south along the Rio Grande, soldiers and Border Patrol agents are also integrating unmanned surface vessels (USVs) to support long-endurance surveillance missions. These solar-powered watercraft can reportedly remain operational for up to six months without refueling or major maintenance, providing continuous river monitoring within the South Texas National Defense Area.

Their sensor feeds integrate into shared interagency systems, improving the common operating picture and enabling quicker response to detected movement along the river corridor.

Autonomous systems are being used not only to patrol and detect activity, but also to physically shape the terrain through barrier emplacement and wire installation, creating a layered manned-unmanned border security framework.
