A white pentagon with concave sides 2 3/8 inches (6.03cm) outside diameter similarly pierced 1 inch (2.54cm) outside diameter, all on a dark blue disc background 2 1/2 inches (6.35cm) in diameter.
The design was arbitrarily selected to represent the 5th Corps Area Service Command. White, being a mixture of all colors, was 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.
The 5th Service Command was located in Columbus, Ohio, and the Command was responsible for the states of Indiana, Kentucky, Ohio and West Virginia. The 5th Command patch was originally approved on 18 Jul 1941. The shoulder sleeve insignia was amended on 14 Oct 1941 to change the background from olive drab to dark blue.
