Any person who commits an offense named in this section must be tried in a circuit court of this State, and jurisdiction is conferred upon that court for that purpose. Upon conviction, such a person must be punished by a fine of not more than five hundred dollars, or imprisonment for not more than six months, or both. The attorney general or his designated representative shall, upon the certification of the facts to him by the military court, prosecute any person violating this section.
