The Chief of Police may appoint, for a specified time, as many reserve officers as may be necessary. Reserve officers shall be subordinate to the Chief of Police. Under the provisions of M.S. § 626.84, Subd. 1(g), as it may be amended from time to time, a RESERVE OFFICER is an individual whose services are utilized by a law enforcement agency to provide supplementary assistance at special events, traffic or crowd control, and administrative or clerical assistance. A reserve officer's duties shall not include enforcement of the general criminal laws of the state, and the reserve officer does not have full powers of arrest or authorization to carry a firearm on duty.
