In the case a person who has been honorably discharged from the active military service of the United States, on the presentation to the clerk of the county in which such person resides of an application sworn to by said applicant together with a certificate of honorable discharge from the active military service of the United States, which application shall also set forth that the applicant has resided within the state for at least six months and in the county at least three months immediately preceding his application for license, the county clerk shall forward a copy of such application to the adjutant general of the State for permanent record.
