The U.S. Air Force assumed control of approximately 190 additional miles of the Texas-Mexico border along the Rio Grande River, expanding the total length under its supervision to about 440 miles. This increase in military oversight covers a significant portion of the Texas borderland, aiming to enhance security and operational capabilities along the international boundary.
Previously, the Air Force managed around 250 miles of the Rio Grande riverbank, and the recent expansion allows for broader deployment of military assets in the region. The increased military presence coincides with ongoing efforts by federal and state authorities to address border security challenges amid fluctuating migration flows and cross-border criminal activity.
The U.S. Border Patrol reported 237,538 encounters with migrants in the fiscal year 2025, which began in October 2024, reflecting a complex migration environment. In January 2026, Border Patrol apprehended 6,070 individuals, the lowest monthly total for child and family migrants since at least 2011. These figures demonstrate ongoing shifts in migration patterns on the southern border.
This development follows heightened tensions and security concerns on both sides of the border. Mexican security forces intensified cooperation with their U.S. counterparts despite operational limitations set by national laws. In February 2026, Mexico conducted a high-profile operation targeting the leader of the Jalisco New Generation Cartel, one of the country’s most notorious criminal organizations. The raid resulted in fatalities and raised questions about stability ahead of major international events, including the 2026 World Cup.
Texas Governor Greg Abbott urged residents to heed federal travel warnings amid escalating violence in parts of Mexico, particularly in border states such as Tamaulipas. U.S. government agencies issued travel advisories recommending increased caution when traveling in certain regions due to terrorism, crime, and ongoing security operations.
The expansion of military control along the Texas border reflects the U.S. government’s multifaceted approach to border security. Alongside physical barriers, technological enhancements and increased personnel deployment form part of the strategy to secure the border and manage migration. As of January 2026, contracts had been awarded for constructing 587 miles of border barrier, reinforcing existing infrastructure and surveillance capacities.
This period also involved coordination between U.S. and Mexican officials to implement joint security initiatives, particularly in advance of major sporting events scheduled in 2026. These efforts underline the continuing complexity of managing the shared border while addressing criminal threats and humanitarian concerns on both sides.
