U.S. Marines, assigned to Task Force Sapper, supporting Joint-Task Force Southern Border (JTF-SB) conduct operations of general engineering- barrier reinforcements along the Mexican and U.S. American southern border barrier near San Diego Calif., January 6, through June 11, 2025. Task Force Sapper is composed of 500 Marines and sailors from I Marine Expeditionary Force who have been tasked with engineering support to U.S. Northern Command with the emplacement of physical barriers on the Southern Border barrier to add additional security that will curtail illegal border crossings. Under the direction of the U.S. NORTHCOM, Joint Task Force–Southern Border aligns efforts to seal the southern border and repel illegal activity and is responsible for full-scale, agile, and all-domain operations, which will allow for more effective and efficient DoD operations.
