The deployment authorized by the SPP under the joint management of State and Federal governments can only be in the "State Partnership" relationship, which according to the current United States Code (USC) is defined as a "program of activities." The Secretary of Defense is authorized to establish it between the "military forces," the "security forces," or the "governmental organizations" designed to respond to disasters or other emergencies, and the "National Guard of a state or territory." The nature of the activities is that they must support United States "Security Cooperation" (SC) objectives.
