Gules, five fleurs-de-lis one, three and one, Or, on a chief embattled Azure fimbriated of the second a demi-sun issuant of the like, a bordure of the last.
That for the regiments and separate battalions of the Wyoming National Guard: On a wreath of the colors Or and Gules, an American bison statant Proper.
LET ‘ER BUCK.
The use of the shield of the coat of arms originally approved for the 115th Cavalry Regiment, differenced by a border, indicates the descent of the Battalion from that organization. The red shield and the five gold fleurs-de-lis are for Artillery service in France during World War I. The chief is blue for the Infantry service in the Philippines. The gold sun recalls both the service in the Far East and the shoulder sleeve insignia of the 41st Division. The parting line is yellow for the Cavalry assignment of the unit and is made embattled to represent the fighting record of the old organization.
The crest is that of the Wyoming National Guard.
The coat of arms was approved on 6 August 1954. It was rescinded on 3 August 1961.
