Shoulder Sleeve Insignia

Description
A six arm cross in white, 7/8 inch (2.22cm) in width and 2 1/8 inches (5.40cm) overall, pierced by a hexagon 5/8 inch (1.59cm) across flat surfaces with one point up, all on a dark blue disc background 2 1/2 inches (6.35cm) in diameter.

Symbolism
The design is arbitrarily selected to represent the 6th Corps Area Service Command. White, being a mixture of all colors, has been selected for the reason that Corps Area Service Commands may be composed of all arms and services. The geometric design represents the Command's numeric designation.

Background
The 6th Service Command Headquarters was located in Chicago, Illinois and the Command was responsible for the states of Illinois, Michigan and Wisconsin. The shoulder sleeve insignia was originally approved on 17 Jul 1941. It was amended on 14 Oct 1941 to change the background from olive drab to dark blue.
