Authorised 22 October 1925
A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall: An Indian in breech clout and war bonnet, mounted on a galloping pony, brandishing a rifle in his right and holding a single rein in his left hand, all in gold, displayed upon a five-bastioned fort in blue edged with gold.
The five-bastioned fort was the badge of the Fifth Army Corps in Cuba, of which the Ninth Cavalry was a part. The yellow outline is for the Cavalry, and the blue for active service in the Spanish-American War. The mounted Indian represents the Indian campaigns of the Regiment.
The distinctive unit insignia was originally approved for the 9th Cavalry Regiment on 22 October 1925. It was redesignated for the 509th Tank Battalion on 23 May 1951. It was amended to change the symbolism on 31 July 1951. The insignia was redesignated for the 9th Cavalry Regiment on 1 October 1958. Coat of Arms
