The rank of the Noncommissioned officers is indicated by chevrons worn with the point up upon the sleeves of all coats and the flannel shirt midway between the shoulder and the elbow.
The chevrons for the dress coat are made of stripes of yellow silk braid one-half of an inch wide on a backing of scarlet cloth, the total width of the chevron being eight inches.
The chevrons for the summer field coat and for the flannel shirt are made of cloth of a darker shade than the coat, the stripes being three-eighths of an inch in width and the whole chevron being three and one-half inches wide.
