Securing the U.S. Border With Military Involvement
President Trump has expanded the military’s role in securing the southern border through a new memorandum, which supplements Executive Order 14167. This directive, issued on January 20, 2025, calls for the military’s integration with federal agencies, including Defense, Interior, Agriculture, and Homeland Security, to bolster the border’s integrity. The plan prioritizes curbing unlawful entries, deemed essential for maintaining U.S. sovereignty and security.
The directive permits strategic deployment of military assets, surveillance, and deterrence measures. Federal lands, particularly the Roosevelt Reservation, are accessible for military operations. The directive impacts the U.S. states sharing the Mexican border, namely California, Arizona, New Mexico, and Texas, authorized under the memorandum.

Military personnel will adhere to existing force guidelines and may call upon the National Guard if necessary.

President Trump announced converting a narrow strip along the border into a designated military installation. Authority over this 60-foot-wide strip, known as the Roosevelt Reservation, now lies with the Department of Defense, allowing for potential conflicts with laws regarding troop use in domestic law enforcement.

Rapid Response and Future Projections
The initiative, marked by direct military involvement, is seen as a mechanism to address diverse threats at the southern border. The strategy includes provisional detention of migrants trespassing military jurisdiction, with Border Patrol responsible for making formal arrests. Military and quasi-military personnel will dynamically adapt based on ongoing logistical considerations.

While certain areas have seen decreased illegal crossings, the expanded military presence promises comprehensive coverage. The designation of “National Defense Areas” facilitates jurisdictional control transitions to the Department of Defense, prioritizing fast, adaptable responses to border challenges.
