"The President has the authority to deploy troops within the United States to enforce the laws. The Enforcement of the Laws to Restore Public Order, Chapter 15 of Title 10 USC (formerly Insurrection Act) authorizes the President to employ the Armed Forces of the US, including the NG, within the United States to restore order or enforce federal law after a major public emergency (e.g., natural disaster, serious public health emergency, or terrorist attack) when requested by the state governor or when the President determines that the authorities of the state are incapable of maintaining public order. The President normally executes his authority by ordering the dispersal of those obstructing the enforcement of the laws. The President may act unilaterally to suppress an insurrection or domestic violation without the request or authority of the state/governor and to exercise his "major public emergencies" authority to direct the SecDef to provide supplies, services, and equipment necessary for the immediate preservation of life and property. Such supplies, services, and equipment may be provided: only to the extent that the constituted authorities of the state or possession are unable to provide them; only until such authorities and other departments and agencies of the United States charged with such responsibilities are able to provide them; and only to the extent that their provision, in the judgment of the SecDef, will not interfere with the preparedness of ongoing military operations or functions. Responsibility for the coordination of the federal response for civil disturbances rests with the Attorney General. Any DOD forces employed in civil disturbance operations shall remain under military authority at all times Forces deployed to assist federal and local authorities during times of civil disturbance follow the use-of-force policy found in CJCS Instruction (CJCSI) 3121.01B, Standing Rules of Engagement/Standing Rules for the Use of Force for US Forces".
