Shield
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.
Crest
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 It was rescinded on 3 August 1961.
