Mississippi Code Title 33. Military Affairs § 33-7-305

It shall be the duty of the Governor, when ordering out any portion of the National Guard, for active state duty, to issue his orders to the officer in command of such troops as he may have ordered out, directing him as to the duty to be performed and the kind and extent of force to be used in the performance of such duty, and if the troops are so ordered out for the purpose of aiding the civil authorities, he shall designate in his order the civil authorities, if any, to be consulted by the commander of the troops and to what extent the troops will cooperate with or take orders from the civil authorities. When an armed military force is ordered out in aid of civil authorities, the orders of the civil officer or officers shall not extend beyond a direction of the general or specific objects to be accomplished. The tactical direction of the troops, the kind and extent of the force to be used, and the particular means to be employed are left solely with the military officers, subject to the orders received from the commander in chief.
