The regiment was organized in 1901 and saw service in the Philippines. This is indicated by the crossed bolos with red blades and blue hilts. The regiment rendered very good service on the Mexican Border in 1916 and this is indicated by the cactus. The regimental colors, black and yellow, are shown by the shield and the black border within the edge and by the color of the crest which shows against the yellow regimental flag.
The coat of arms was originally approved for the 11th Cavalry Regiment on 25 August 1921. It was redesignated for the 11th Armored Cavalry Regiment on 26 November 1951.
