ShieldThe symbolism and pictorial content of the original coat of arms of the former 6th Field Artillery and 6th Coast Artillery have been retained with as little change as possible. The order on the shield represents oldest service at the top and most recent at the bottom. The rattlesnake is for service in the Mexican War by the 6th Field Artillery. The six rattles represent the numerical designation of both units. The crossed sabers represent Civil War service in the Army of the Potomac. The star represents service in the Philippine Insurrection, being taken from the banner of Katipunan; the two fleurs-de-lis are used to represent service in World Wars I and II.
CrestThe crest is for service as the first horse artillery in the Army, by the 6th Field Artillery.
The coat of arms was approved on 15 May 1959. It was cancelled on 23 May 1971.
