Process and mandates may be directed to the provost marshal, the military police, or any licensed peace officer of the state and shall be in such form as may be prescribed by rules issued under this code.

Subd. 3. Execution of process or mandates.

All officers to whom process or mandates may be so directed shall execute them and make return of their acts thereunder according to the requirements of those documents. Except as otherwise specifically provided in this code, no such officer may demand or require payment of any fee or charge for receiving, executing, or returning such a process or mandate or for any service in connection therewith.
