U.S. Military to Announce Two New "National Defense Areas" on Southern Border

The U.S. military is expected to announce the creation of two new "National Defense Areas" (NDAs) along the southern border this week, according to three U.S. officials. These zones are designated extensions of military installations, granting troops the authority to temporarily detain migrants before transferring them to civilian law enforcement agencies.

One of the new National Defense Areas will be established in Texas, encompassing approximately 250 miles of the Rio Grande River. This zone will be attached to Joint Base San Antonio. The second NDA will be located in Arizona, extending more than 100 miles along the border and linked to Marine Corps Air Station Yuma.

The establishment of these NDAs marks a further expansion of the military's role in border security. By designating these areas as extensions of existing military installations, the administration aims to provide a legal framework for military personnel to engage in the temporary detention of individuals. This strategy allows for military involvement without necessarily invoking broader emergency powers, such as the Insurrection Act of 1807, which traditionally governs the deployment of military forces for domestic law enforcement.

Previous National Defense Areas have already been established in New Mexico and a stretch of western Texas, where troops have begun detaining individuals accused of trespassing. While these zones are intended to be a deterrent and a mechanism for increased border control, legal challenges have arisen concerning whether migrants are adequately informed they are entering a restricted military zone.

The announcement of these new zones underscores the ongoing focus on immigration and border enforcement as a key priority for the current administration. The move is expected to draw both support from those advocating for stronger border security and criticism from civil liberties and immigrant rights groups concerned about the militarization of the border and potential impacts on due process.
