A shield 3 inches (7.62 cm) in height and 2 inches (5.08 cm) in width its upper edge a convex arch, having a 1/8 inch (.32 cm) white border around a blue field with a zigzag yellow band arched across the upper third and below it a white wheel with twelve pointed cogs containing within it a square with point up having a yellow edge around four quarters of blue and yellow, the yellow quarters placed vertically.
The Aurora Borealis, a phenomenon familiar to Alaska, is represented by the yellow zigzag arch and the white and blue colors suggest the colder climate of the region. The cogged wheel simulates the driving wheel of a tracked vehicle such as might be used in snow and rough terrain, alluding to the aspect of logistics dealing with transportation. Inside the wheel the box refers to supplies and its division into four parts applies to the provision of quarters or housing.
The shoulder sleeve insignia was approved on 1 June 1967. (TIOH Dwg. No. A-1-455)
