(c) Any person who unlawfully assaults or fires at, or throws any missile at, against, or upon any member or body of the militia or National Guard, or civil officer, or other person lawfully aiding them, when assembling or assembled for the purpose of performing any duty under the provision of this section, must, on conviction, be imprisoned in the penitentiary for not less than two (2) years, nor more than five (5) years.

(d) If any portion of the militia or National Guard, or person lawfully aiding them in the performance of any duty under the provisions of this section, are assaulted, attacked, or are in imminent danger thereof, the commanding officer of such militia or National Guard need not await any orders from any civil magistrate, but may at once proceed to quell such attack, and take all other needful steps for the safety of his command.
