Joint Task Force 51

Joint Task Force 51 (JTF-51) is a contingency command post under United States Army North (USARNORTH), responsible for coordinating Defense Support of Civil Authorities (DSCA) within the United States. JTF-51 is headquartered at Joint Base San Antonio-Fort Sam Houston, Texas, and operates under the authority of United States Northern Command (USNORTHCOM). The task force is designed to provide rapid-response command and control capabilities for federal military support to civilian agencies during natural disasters, emergencies, and homeland security operations. Major General Scott M. Sherman assumed command of Joint Task Force 51 on September 29, 2024, succeeding Maj. Gen. William J. Prendergast.

History

JTF-51 was established to enable USARNORTH to quickly deploy a scalable, joint command post in response to requests for federal assistance from state or federal agencies following disasters or emergencies. The task force was first operationally tested in the mid-2000s, with its mission and structure evolving in response to major incidents such as Hurricane Katrina, though the primary joint military response at that time was organized under Joint Task Force Katrina. Since then, JTF-51 has played a significant role in disaster relief operations, including response efforts during hurricanes Harvey, Irma, and Maria, as well as the COVID-19 pandemic.

COVID-19 Pandemic Response

During the COVID-19 pandemic, JTF-51 deployed to California and the Navajo Nation to provide command and control for military medical personnel, supporting civilian healthcare providers and coordinating the arrival of Army, Air Force, and Navy rapid response teams. The task force managed the integration and sustainment of military medical teams across several states, ensuring effective support for overwhelmed healthcare systems.

2025 Los Angeles Deployment

In response to the June 2025 Los Angeles protests, JTF-51 was activated under USNORTHCOM to coordinate the deployment of federal military forces to Los Angeles County. The operation involved federalized National Guardsmen and U.S. Marines, tasked with protecting federal personnel and property during protests related to immigration enforcement actions. The National Guard troops, federalized under Title 10 authority, were deployed primarily for force protection and were not authorized to conduct law enforcement operations such as arrests or searches. Marines received specialized training in crowd control and de-escalation tactics prior to deployment.

U.S. military forces under JTF-51 deployed to Los Angeles County currently include:

* 2,100 soldiers of the 79th Infantry Brigade Combat Team, California National Guard under Title 10 status
* 700 Marines from 2nd Battalion, 7th Marines, 1st Marine Division
Approximately 2,000 other California National Guardsman have been placed under Title 10 status, but have not been deployed to Los Angeles County.

Organization & Mission

JTF-51 operates under U.S. Northern Command (USNORTHCOM) and serves as an initial entry coordinating element. It works alongside FEMA, state and local officials, and Dual Status Commanders to facilitate military support for civil authorities. JTF-51 is structured to deploy rapidly and ensure effective coordination between military and civilian agencies during crises.

The primary mission of JTF-51 is to provide command and control capabilities for military forces supporting disaster response efforts.

Controversy

The 2025 deployment of JTF-51 to Los Angeles sparked protests and legal challenges, with California officials, including Governor Gavin Newsom, opposing the federalization of the National Guard and filing lawsuits to challenge the federal government's authority to deploy troops without state coordination. While JTF-51 troops were authorized to temporarily detain individuals for force protection, they were not permitted to make arrests or enforce immigration laws directly. The deployment and its legal implications remain a subject of public and policy debate.{{Cite web , last=Ball , first=Molly , title=Newsom Leans Into L.A.
