Shield
Blue, white and red represent the Tricolor of France and signify that the entire combat service of the predecessor organization was as a unit of the French Army during World War I. The wavy chevron represents the first front line sector held by the Regiment at the junction of the Aiane and Tourbe Rivers. The principal military achievement of the Regiment was its participation in the Meuse-Argonne battle; the five poplar trees represent the Argonne Forest and denote the five days the Regiment was in the attack in that battle (26 September-1 October 1918). The rattlesnake perpetuates the distinctive regimental insignia adopted early in April 1918, and worn by the organization throughout the remainder of its service in World War I. The motto, "DON'T TREAD ON ME," was adopted at the same time as the insignia.
