ShieldThe Regiment was organized in 1922 from personnel transferred from the 25th Field Artillery which in turn has been formed from personnel of the 4th Philippine Infantry and the 45th Infantry. The shield is blue for the old Infantry Regiments and also for the color of the sea, which surrounds the Islands. The sun is similar to one which appeared on a flag of the Philippine Insurrection. The twelve rays refer to the twelve principal tribes from which the soldiers of the Regiment came, i.e., Ilocanos, Cagayanes, Pangasinans, Zambals, Pampangos, Igorots, Tagalogs, Bicols, Ilongots, Samars, Cebuanos, and Moros.
CrestThe crest signifies the dashing spirit of the Cavalry service.
The coat of arms was approved on 20 August 1924. It was rescinded on 2 February 1959.
