Most of California’s border with Mexico will be converted into a militarized zone to expand security operations and support the Trump administration’s immigration enforcement efforts.

Designated area

According to Border Report, the area will extend from the Arizona state line to the Otay Mountain Wilderness, passing through the Imperial Valley and multiple border communities. The area will be transferred to Navy control to reinforce the historic role public lands have played in safeguarding national sovereignty.

Interior Secretary Doug Burgum stated that working with the Navy to close long-standing security gaps strengthens national defense, protects public lands from unlawful use, and advances the President’s agenda.

Militarized zone operations

The Trump administration has established multiple militarized areas throughout the southern border. Service members patrol these zones and detain individuals attempting to cross into the country unlawfully. Those apprehended are charged with trespassing on military property and illegal entry.

Troops have expanded their role in immigration enforcement by conducting direct arrests of migrants attempting to cross the border.

First arrests

The initial arrests in militarized zones occurred in early June after three migrants entered such an area in New Mexico. They were transferred to Customs and Border Protection (CBP) and charged with illegally entering militarized areas.
