Border Wall Models Thwart U.S. Commandos in Tests

Border Wall Models Thwart U.S. Commandos in Tests, by Breitbart.

Recent assaults by tactical teams on prototypes of President Donald Trump’s proposed wall with Mexico indicate their imposing heights should stop border crossers, a U.S. official with direct knowledge of the rigorous assessment told The Associated Press.

Military special forces based in Florida and U.S. Customs and Border Protection special units spent three weeks trying to breach and scale the eight models in San Diego, using jackhammers, saws, torches and other tools and climbing devices, said the official, who spoke on condition of anonymity because the information was not authorized for public release.

A Customs and Border Protection report on the tests identifies strengths and flaws of each design but does not pick an overall winner or rank them, though it does point to see-through steel barriers topped by concrete as the best overall design, the official said. …

The highly trained testers scaled 16 to 20 feet (4.9 to 6.1 meters) unassisted but needed help after that, said the official who described the assaults on the wall prototypes to the AP. Testers also expressed safety concerns about getting down from 30 feet. …

The report favors steel at ground level because agents can see what is happening on the other side and holes can more easily be patched, the official said. With concrete, large slabs have to be replaced for even small breaches, which is time-consuming and expensive. Topping the steel with smooth concrete surfaces helps prevent climbing.
