In situations described in this subsection, the commanding officer may apprehend a person on a state military base, armory base, air base, or a vital resource of this state or of the United States if the commanding officer has reasonable cause to believe the person has committed a felony or a misdemeanor punishable by imprisonment for more than 92 days on that state military base, armory base, air base, or a vital resource of this state or of the United States.

That commanding officer shall determine the amount and kind of force to be used in preserving the peace and carrying out the orders of the governor. Except as provided in subsection (3), that commanding officer's honest and reasonable judgment under the circumstances then existing, in the exercise of his or her duty, is full protection, civilly and criminally, for an act done in the line of duty, and a member of the organized militia in active service, special duty, active state service, or the service of the United States is not liable civilly or criminally for an act committed by him or her in the performance of his or her duty.
