Description
On a blue shield rounded at base within a 1/8 inch (.32cm) red border 2 1/4 inches (5.72cm) in width overall, a white five-pointed star with a detached and tapered red ray between and within each of the points.

Symbolism
The white star on a blue field was suggested by the first official flag of the Republic of Texas adopted in May 1836 from the design of Lorenzo de Zavala, a native of San Antonio, Texas. To this has been added red rays which allude to the courage of all Texans who have fought gallantly in all wars since 1826, and a red border which refers to the blood shed in protecting not only the liberties of the United States but the liberties of all.

Background
The shoulder sleeve insignia was approved on 10 May 1967. It was cancelled on 1 Nov 1973. (TIOH Drawing Number A-1-452)
