US Military Expands Border Security Operations With 3,000 Troops

Thousands of U.S. troops are being deployed to the southern border as the Trump administration intensifies its security strategy. Defense Secretary Pete Hegseth approved the deployment Friday, marking another step in the Pentagon’s ongoing effort to strengthen border defenses.

Among the units being sent are soldiers from the 4th Infantry Division’s 2nd Stryker Brigade, stationed at Fort Carson, Colorado. These forces will be accompanied by aviation battalions specializing in intelligence and logistical support. Officials say the troops will integrate with existing security operations, assisting federal agencies in preventing illegal crossings.

The Pentagon’s latest decision follows a previous deployment in January, which sent 1,500 additional service members to the border. These personnel joined the roughly 2,500 National Guard and Reserve troops already assigned to border security duties.

Stryker combat vehicles, known for their speed and versatility, are also being transported to the border. These vehicles have been used in past military operations and are expected to play a role in patrol and surveillance efforts along key regions, including Arizona.

Mexico has stepped up its own security efforts, with National Guard troops stationed near Tijuana as part of a larger strategy tied to negotiations between President Donald Trump and Mexico President Claudia Sheinbaum.

Military officials anticipate that troops will begin arriving within weeks, with further deployments remaining a possibility depending on border conditions.
