“Under 18 U.S.C. § 831, the Attorney General may request that the Secretary of Defense provide emergency assistance if civilian law enforcement is inadequate to address certain types of threats involving the release of nuclear materials, such as potential use of a nuclear or radiological weapon.

Although use of the military for law enforcement purposes in the United states is generally prohibited by the Posse Comitatus Act, Title 10 of the US Code expressly allows the Secretary of Defense to make military personnel available to train Federal, State, and local civilian law enforcement officials in the operation and maintenance of equipment”
