SHOULDER SLEEVE INSIGNIA. Description: On a light khaki square, each side 2 inches (5.08 cm) in width overall and with one angle up, four green ivy leaves arranged per cross issuing from a small open circle (one leaf in each angle of the square and the vertical and horizontal axis each 2 11/32 inches (5.95 cm) in length) all within a 1/8 inch (.32 cm) light khaki border.
Symbolism: The four leaves allude to the numerical designation of the Division while the word "I-VY" as pronounced, suggests the characters used in the formation of the Roman numeral "IV." Ivy leaves are also symbolic of fidelity and tenacity.
Background: The shoulder sleeve insignia was originally approved for the 4th Division on 30 October 1918, without any background specified for the ivy leaf design. The design was embroidered on a square olive background (color of the uniform). It was redesignated for the 4th Infantry Division effective 4 August 1943. On 2 July 1958, the design was changed to reflect the light khaki color background. The insignia was amended to add a symbolism on 1 April 1969. (TIOH Dwg. No. A-1-79)
