The U.S. military has deployed advanced ground-based radar systems along the southern border to enhance detection and tracking of drones used by Mexican drug cartels, according to specialized defense-industry news site The War Zone (TWZ).
The report comes a day after the Navy assigned a guided-missile destroyer, the USS Gravely, to U.S. Northern Command (USNORTHCOM) operations supporting border security, a rare deployment for a vessel of its type in this region.
