On an ultramarine blue shield 2 3/4 inches (6.99 cm) in height and 2 inches (5.08 cm) in width a winged unicorn issuant from base in golden orange. Worn above the shield a black tab with the word "AIRBORNE" in golden orange letters.
The unicorn is associated, by tradition, with qualities of virtue, courage and strength. The horn of the unicorn signifies extreme courage. All of such virtues should be cultivated in all units. It is hoped that these virtues will be conspicuous in the 13th Airborne Division. The unicorn has been winged to represent its travel in the air as "Airborne." The blue background is the color of the Infantry, which is the basic arm of the Division, and also indicates the sky, which is the distinctive medium of travel for the Division.
The shoulder sleeve insignia was approved on 2 June 1943.
