Interesting side note: Commodore Decker's insignia doesn't have a command symbol on it.
Neither does the Antares
"merchant" patch (instead it's some cross-like stitching, or perhaps a "twinkling star"). The absence of the star/ellipses/spiral division symbols is a detail gotten wrong in the commonly available illustrations of these patches on the web. It's like fans feel compelled to retcon those symbols into the patches.
