On a shield 2 1/4 inches (5.72 cm) in width overall divided horizontally into thirds, the lower two-thirds brick red bearing a yellow wheel and the upper third white crossed horizontally by a blue wavy bar and all surmounted by two brick red vertical bars all within a 1/8 inch (.32 cm) yellow border.
The colors brick red and yellow (gold) are used for the Transportation Corps. The wheel, a basic implement of mobility, and the white and wavy blue area, symbolic of water, refer to the terminal port function of the organization. The two white and the one blue areas also allude to the three activations of the unit (initially in the United States and subsequently in Korea and France), and the two vertical bars simulating wharves and docks also simulate the numeral "11," the organization's numerical designation.
The shoulder sleeve insignia was approved on 14 January 1969. (TIOH Drawing Number A-1-513)
