Pentagon Deploys Mechanized Infantry And Air Support To Secure Mexico Border, Including Team Of 4,400 Soldiers

The Pentagon is deploying a Stryker Brigade Combat Team and a General Support Aviation Battalion to the southwestern border, accelerating efforts to fulfill President Trump’s directive to bolster military support in securing the U.S. – Mexico border. The units, equipped with wheeled vehicle and air capabilities, are set to reinforce border operations in the coming weeks, Pentagon Press Secretary Sean Parnell announced over the weekend.

Each SBCT is a mechanized infantry force of approximately 4,400 soldiers, and the Army’s nine SBCTs — seven active-duty and two National Guard — are known for their rapid deployment and versatility. Built around the Stryker vehicle — an eight-wheeled armored platform — the brigade balances mobility, protection and firepower. Capable of transport via C-130 Hercules aircraft within 96 hours, the Stryker excels in operations requiring swift response. 

Complementing this, the GSAB, with roughly 650 troops, brings aviation muscle — UH-60 Black Hawks for command and medical evacuation, and CH-47 Chinooks for heavy lift — enhancing operational reach and support.  

The Stryker’s design — lighter than tanks, yet more robust than light infantry — makes it ideal for the border’s vast terrain, while the aviation battalion’s air traffic control and lift capacity ensure seamless coordination. 

“These forces will arrive in the coming weeks, and their deployment underscores the department’s unwavering dedication to working alongside the Department of Homeland Security to secure our southern border and maintain the sovereignty, territorial integrity and security of the United States under President Trump’s leadership,” Parnell said in a statement today.

This deployment marks the latest wave of active-duty troops sent to the border since Trump’s inauguration on Jan. 20, 2025. Following his declaration to “seal the border” and combat illegal immigration and drug trafficking, initial deployments included 1,600 Marines and soldiers by late January, joining 2,500 reservists already mobilized.  

Defense Secretary Pete Hegseth, addressing the mission’s scope on his first official day in late January, emphasized adaptability. “Whatever is needed at the border will be provided,” he said, signaling a robust commitment to the president’s homeland defense priority.
