The U.S. Army enlisted rank insignia that was used during World War II differs from the current system. The color scheme used for the insignia's chevron design was defined as either silver grey on dark blue, olive drab on dark blue, or khaki on dark blue (as seen in the charts below). This scheme of rank insignia was established by War Department Circular No. 303 on 5 August 1920 and would see two significant changes in 1942.
