Each bar gemel represents the two rivers between which the regiments fought; first, between the Vesle and the Aisne; and the second bar, the Aire and the Meuse.
The most brilliant action of the regiment was in the taking if the town of St Juvin on the Aire River on the 1918-10-14 (St. Juvin was a hermit shepherd), and the shepherd's crook represents this action.
The fleurs-de-lis indicate the two major offensives of the regiment.
