Top defense officials toured sections of the U.S.-Mexico border over the weekend to see how the military could reinforce efforts to block drug smuggling and other illegal activity.
Acting Defense Secretary Patrick Shanahan and General Joseph Dunford visited a border site near El Paso called Monument Site 3, where a stretch of 18-foot border wall stands atop a huge landfill.
The Department of Homeland Security has requested the Pentagon to help in operating surveillance cameras, which can see as far as eight miles away.
These projects are separate from, but related to, those which Shanahan is expected to pay for by diverting money that Congress appropriated for military construction projects.
