The stylized blue arrow and sword are used to represent the purpose and military might of the II Field Force pressing against, sweeping back, and breaking through enemy forces symbolized by the red areas. The dividing of the red and yellow areas of the shield into two parts allude to the numerical designation of the II Field Force, the colors red and yellow also being those of Vietnam. The colors red, white and blue are the national colors of the United States and further allude to the three major combat arms: Infantry, Artillery and Armor. Background The shoulder sleeve insignia was approved on 5 October 1966. (TIOH Dwg. No. A-1-437) ==Distinctive unit insignia==
