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 Drawing Number A-1-79)
