On 19 December 1917, "Special Regulation 41" stated that the Army Field Clerk and Quarter Master Corps Field Clerk ranks were authorized the same uniform as an officer. Their rank insignia was now a freework pin of crossed quill pens on either side of the freework "U.S." pins worn on the standing collar of the M1909 tunic. They were not permitted the brown mohair cuff braid band of an Army officer, but were authorized a silver-and-black braid hatcord for wear with the M1911 Campaign Hat and the officer's "G.I. Eagle" on the M1902 peaked cap.
