<p>SHOULDER SLEEVE INSIGNIA 
</p>
<ul><li><b>Description:</b> On a yellow triangular Norman shield with rounded corners 5 1/4 inches in height overall, a black diagonal stripe extending over the shield from upper left to lower right and in the upper right a black horse's head cut off diagonally at the neck all within a 1/8 inch green border.</li></ul><ul><li><b>Symbolism:</b> Yellow, the traditional cavalry color, and the horse's head refer to the division's original cavalry structure. Black, symbolic of iron, alludes to the transition to tanks and armor. The black diagonal stripe represents a sword baldric and is a mark of military honor; it also implies movement "up the field" and thus symbolizes aggressive elan and attack. The one diagonal bend, as well as the one horse's head, also alludes to the division's numerical designation.</li></ul><ul><li><b>Background:</b> The shoulder sleeve insignia was originally approved January 3, 1921 with several variations in colors of the bend and horse's head to reflect the subordinate elements of the division. The current design was authorized for wear by all subordinate elements of the division on December 11, 1934 and previous authorization for the variations was cancelled.</li></ul>
