When requested to render mutual aid or exercises and training for mutual aid, the National Guard shall take such action as is necessary to provide and make available the resources covered by this compact in accordance with the terms thereof, provided that it is understood that the National Guard when rendering aid may withhold resources to the extent necessary to provide reasonable protection for the state. The National Guard shall afford to the emergency forces of any other member state, while operating within its state limits under the terms and conditions of this compact, the same powers (except those of arrest), duties, rights, and privileges as are afforded forces of the state in which they are performing emergency services. Emergency forces will continue under the command and control of the National Guard regular leaders, but the organizational units will come under the operations control of the Adjutant General of the state receiving assistance. Under no circumstances will the assisting member states use force within the boundaries of the other states without express federal authority. The assisting member states may assist in the support of a state using authorized police powers within its own boundaries but will not participate as part of the state police force without express federal authority. The assisting member state shall not be used to suppress riots or tumults or provide direct support to these activities without federal authority.
