Vt. Stat. tit. 20 § 205
Any party jurisdiction requested to render mutual aid or conduct exercise and training for mutual aid shall undertake to respond as soon as possible, except that it is understood that the jurisdiction rendering aid may withhold or recall resources to the extent necessary to provide reasonable protection for that jurisdiction. Each party jurisdiction shall afford to the personnel of the emergency forces of any party jurisdiction, while operating within its jurisdictional limits under the terms and conditions of this Compact and under the operational control of an officer of the requesting party, the same powers, duties, rights, privileges, and immunities as are afforded similar or like forces of the jurisdiction in which they are performing emergency services. Emergency forces continue under the command and control of their regular leaders, but the organizational units come under the operational control of the emergency services authorities of the jurisdiction receiving assistance. These conditions may be activated, as needed, by the jurisdiction that is to receive assistance or upon commencement of exercises or training for mutual aid and continue as long as the exercises or training for mutual aid are in progress, the emergency or disaster remains in effect, or loaned resources remain in the receiving jurisdiction or jurisdictions, whichever is longer. The receiving jurisdiction is responsible for informing the assisting jurisdictions of the specific moment when services will no longer be required.
