Pentagon Sends Additional Troops To Border As Security Measures Expand

A new wave of military personnel is heading to the southern border as part of an expanded effort to curb illegal crossings. Defense Secretary Pete Hegseth approved the deployment of up to 3,000 troops — which will join forces already stationed along the U.S.-Mexico border.

The new arrivals will include soldiers from Fort Carson’s 4th Infantry Division — specifically the 2nd Stryker Brigade Combat Team. These troops will be backed by an aviation battalion and will integrate with National Guard and Reserve members already in place. Their mission is to reinforce security operations and provide logistical support to federal agencies.

Military equipment — including Stryker combat vehicles — is also being transported to border regions. These vehicles, which have been used in combat operations overseas, will enhance mobility and allow for rapid response in key areas such as Arizona. The Pentagon has coordinated with law enforcement officials to position these assets in strategic locations.

This deployment follows a similar move in January when 1,500 active-duty troops were sent to the region. That deployment supplemented the thousands of National Guard members already working to maintain security at major crossing points. Officials say this latest wave will further strengthen enforcement efforts.

Mexico’s government has also increased security on its side of the border. President Claudia Sheinbaum has directed National Guard troops to patrol high-traffic areas — particularly in Tijuana — as part of discussions with the U.S. over trade and immigration policy.

Officials expect these newly deployed forces to arrive in the coming weeks. The Pentagon has indicated that additional reinforcements could be considered if necessary.
