The palm tree is indicative of service in the Philippines; and the giant cactus connotes service on the Mexican border. The motto translates to "Ready and Willing."

The insignia was redesignated for the 147th Artillery Regiment on 18 April 1961. It was redesignated for the 147th Field Artillery Regiment on 28 August 1972. It was amended to correct the motto on 17 January 1973.
