D.C. National Guard Activates 260th Special Purpose Brigade, Creating New Headquarters for Capital Security Support

A new command structure for domestic support missions

The District of Columbia National Guard has activated the 260th Special Purpose Brigade, a newly established unit intended to provide a standing command-and-control headquarters for military support to civil authorities in Washington. The activation ceremony was held March 7, 2026, at the D.C. Armory, marking the unit’s formal entry into service through the uncasing of its colors.

The brigade is designed to organize and coordinate National Guard assistance for public safety operations, protection of critical infrastructure, and interagency coordination in an environment that includes federal institutions, diplomatic facilities, transit hubs, monuments, and dense visitor traffic. The new structure is presented as a dedicated headquarters that can integrate rapidly with federal and District partners when missions require additional forces.

Legal and policy backdrop: Executive Order 14339

The activation follows Executive Order 14339, issued in 2025, which directed the immediate creation, training, manning, and equipping of a specialized unit within the D.C. National Guard dedicated to public safety and order in the nation’s capital. The order also instructed the Department of Defense to ensure National Guard forces in states and territories are organized and prepared to assist civil authorities when circumstances warrant, subject to applicable law and available appropriations.

Washington’s National Guard occupies a distinct status within the U.S. National Guard framework. Unlike state National Guards that typically report to governors for domestic missions, the D.C. National Guard reports to the President, placing it within a federal command relationship that frequently intersects with national-level security planning.

Scale of the current security mission

At the time of the brigade’s activation, approximately 2,500 National Guard personnel were described as supporting the ongoing mission in Washington, providing assistance to the Metropolitan Police Department and helping manage security needs for residents, commuters, and visitors. National Guard support in the District has included activities such as presence at transit locations and support functions intended to supplement law enforcement operations.

Partnerships and operational focus

The brigade’s mission emphasizes coordination with multiple agencies involved in security and public safety in Washington. Federal law enforcement partners referenced in connection with the brigade’s operational environment include the U.S. Marshals Service, reflecting the interagency nature of major-event security and contingency response in the capital.

• Command-and-control planning for military support to civil authorities
• Coordination for critical infrastructure protection missions
• Integration with federal and District security partners during large-scale events and emergencies

Continuity and lineage

The 260th Special Purpose Brigade is framed as inheriting the heritage of the 260th Military Police Command, a prior D.C. National Guard headquarters element that coordinated military police and emergency-support missions in the District before it was inactivated in 2011. The new unit’s insignia incorporates elements of the District flag, linking the brigade’s modern duties to local symbolism and institutional history.

The brigade’s activation establishes a permanent headquarters intended to streamline planning, coordination, and rapid scaling of National Guard support missions in Washington.

Ongoing debate over National Guard roles in domestic public safety

The expanded use of National Guard forces in public-safety contexts in Washington has also intersected with legal and governance disputes, including court challenges and arguments over the appropriate boundaries between military support and civilian law enforcement. Those questions remain active as federal and District officials continue to navigate how Guard forces are used, under what authorities, and for how long such missions should persist.
