Shield
The field of the shield is red, the artillery color. The principal charge is the castle of Ehrenbreitstein debruised by a bendlet carrying the American colors and seventeen stars, to signify the occupation of that castle by the 17th Field Artillery. On a canton is a device from the arms of the parent organization.
Crest
The crest commemorates the two most noteworthy battle incidents. The white mountain is for Blanc Mont. The leaf is taken from Verte Feuille Farm, one of the positions occupied by the Regiment in the Soissons Offensive; the linden was chosen as being very common in the central empires. The fleur-de-lis is from the arms of Soissons.
The coat of arms was originally approved for the 17th Field Artillery Regiment on 25 March 1920. It was amended to correct the blazon of the shield on 15 June 1920. It was redesignated for the 17th Field Artillery Battalion on 27 September 1944. It was redesignated for the 17th Artillery Regiment on 28 November 1958. The insignia was redesignated effective 1 September 1971, for the 17th Field Artillery Regiment.
