The United States military’s expanded presence along the southern border and in the seas is set to continue for several years, according to Air Force Gen. Gregory Guillot.

Speaking before the House Armed Services Committee on Tuesday, April 1, Guillot confirmed that the deployment of active-duty forces, along with naval assets, will remain a critical component of the US national security strategy.

This long-term commitment comes as the US ramps up efforts to curb illegal immigration, combat drug trafficking, and address broader geopolitical challenges in the region.

The Scale of US Military Deployment

Currently, around 6,500 active-duty US military personnel are stationed along the southern border, with that number increasing to approximately 10,000 when naval ships and aircraft are included in the operations.

This expanded force is part of President Donald Trump’s executive order, which was signed a few months ago, designed to enhance border security.

In addition to these ground forces, the US Navy has deployed guided-missile destroyers, such as the USS Spruance (DDG-111) and USS Gravely (DDG-107), along with the USS Normandy (CG-60), to patrol the seas and provide a robust presence in the region.
