Despite the fact that Trump’s fearmongering was his typical hyperbole, more than 10,000 troops are deploying or have deployed to the southern border, according to U.S. Northern Command, or NORTHCOM, which oversees U.S. military activity from Mexico’s southern border up to the North Pole.
Under the direction of NORTHCOM, military personnel — including soldiers from the Fourth Infantry Division at Fort Carson in Colorado, one of the Army’s most storied combat units — have deployed under the moniker Joint Task Force-Southern Border, or JTF-SB, since March, bolstering approximately 2,500 service members who were already supporting U.S. Customs and Border Protection’s border security mission.
One-third of the U.S. border is now completely militarized due to the creation of four new national defense areas, or NDAs: sprawling extensions of U.S. military bases patrolled by troops who can detain immigrants until they can be handed over to Border Patrol agents.
