President Trump announced Sunday that his planned 250-foot triumphal arch near Arlington National Cemetery would serve a second purpose beyond becoming a new Washington landmark: a military security complex equipped for drones, snipers and ammunition.
Trump said the change came at the request of the U.S. military and was being made for national security reasons. The proposed facility would provide space to store and rapidly deploy drones, position snipers on the roof and plaza, and maintain ammunition on site.
