National Guard troops currently deployed to Washington will remain in the nation’s capital through the end of the year, according to a U.S. official familiar with the matter.

The extension, formalized in a memorandum signed Wednesday by Army Secretary Dan Driscoll, represents a significant commitment of military resources to the ongoing security mission in Washington. As of Friday, 2,429 troops were committed to operations in the District of Columbia.

The deployment draws from multiple sources. The D.C. National Guard has contributed 712 personnel, while an additional 1,717 troops have been mobilized from eleven states across the nation. The original deployment was scheduled to conclude at the end of February.

According to the memorandum, “the conditions of the mission” justify extending the deployment to support the administration’s “ongoing efforts to restore law and order” in the capital.

White House officials indicated that President Donald Trump has made clear his intention to utilize all available resources to maintain security in Washington. The National Guard deployment represents one such tool at the administration’s disposal, and officials stated the President will continue to authorize such deployments as circumstances warrant.

The extended mission raises questions about the specific security concerns driving the decision and the financial burden of maintaining such a substantial military presence in the capital for an extended period. National Guard deployments of this scale and duration require coordination between federal authorities and state governors, who maintain command authority over their respective Guard units until they are federalized.

The deployment represents a notable departure from typical National Guard operations, which generally involve shorter-term activations for specific events or emergencies. A mission extending through the end of the year would mark one of the longest sustained Guard deployments to Washington in recent memory.

The troops involved in the mission have been drawn from Guard units with varying specialties and capabilities. The multi-state nature of the deployment suggests a coordinated federal effort to assemble the necessary personnel and resources for the extended mission.

Details regarding the specific duties and rules of engagement for the deployed troops have not been made public. Previous National Guard deployments to Washington have involved a range of activities, from traffic control and crowd management to providing security at federal facilities and supporting law enforcement operations.

The decision to extend the deployment through year’s end indicates the administration’s assessment that current security conditions in the capital require continued military support beyond what local and federal law enforcement agencies can provide independently.

As this mission continues to evolve, questions remain about the criteria that will determine when the National Guard presence is no longer necessary and what conditions would need to change for troops to return to their home states.
