Military patches for rank on kilt?

[Geoff Withnell]

Different services and nations have different traditions. USMC gives a wide latitude and wearing ribbons, medals and badges, but says, so far as I could tell, nothing about rank insignia. I personally wear my ribbons and badges on suitable occasions, and miniature medals for evening wear, since about the only black tie events I go to are military in nature. I don't wear rank insignia because I no longer hold rank. Someone who is retired and still entitled to be addressed by their rank may feel diffrently.
