The 24th Infantry Division traces its lineage to Army units activated in Hawaii. It was activated under the Square Division Table of Organization and Equipment (TO&E) on 1 March 1921 as the Hawaiian Division at Schofield Barracks, Oahu. The division insignia is based on the taro leaf, emblematic of Hawaii. The division was assigned the 21st Infantry Regiment and the 22nd Infantry Regiment, both of which had been assigned to the US 11th Infantry Division prior to 1921.
