Shield
The shield is red for Artillery. A white cross pate was the badge of the 2d Division, 5th Corps, and a white disk the badge of the 2d Division, 1st Corps, of the Army of the Potomac during the Civil War. The disk has been made blue for contrast, conforming to the heraldic law of not placing metal on metal, and to produce the color combination white and blue, symbolizing the service as Infantry. The sheathed Roman sword, taken from the Spanish War service medal, denotes that the organization served within the continental limits of the United States during the Spanish-American War. The fleurs-de-lis represent the service of the 1st Trench Mortar Battalion and the 57th Artillery, Coast Artillery Corps, in France during World War I, which were formed from component parts of the regiment. The number 9 was used by the regiment from the time of its organization in 1859 until 1924.
