The U.S. Army is contributing ground-based radars to help spot and track drones as part of the continued build-up of U.S. military support along the U.S.-Mexican border. Drug cartels in Mexico have been steadily increasing their use of weaponized uncrewed aerial systems, as well as unarmed types for surveillance and smuggling. There are also growing concerns about the threats drones pose to the U.S. homeland, especially military bases and other critical infrastructure.
The Department of Defense released pictures earlier today showing members of the Army’s 10th Mountain Division, based at Fort Drum in New York State, training with the AN/TPQ-53 and AN/MPQ-64 Sentinel radars in Arizona. The 10th Mountain is one of a number of units from across the U.S. military that has sent personnel and material to support the enhanced border security mission that kicked off after President Donald Trump took office in January.
