If no ''M'' device is authorized, the appropriate hourglass shall be positioned in the center of the ribbon. If no hourglass is authorized, the ''M'' device shall be positioned in the center of the ribbon, followed by (worn to the wearer’s left of the “M’ device) Arabic numerals indicating the number of times the device has been awarded, starting with the second award (no number is worn for the first award). If worn alone, the “M” device is centered. If both the hourglass and the ''M'' device are awarded, the “M” device is centered on the ribbon and the hourglass is worn to the wearer’s right. If a numeral is worn, it is placed on the ribbon to the wearer’s left, with the “M” device in the center and the hourglass to the wearer’s right.
