I have seen it and it is more of the Officers style .
and I was enlisted, Enlisted wore all brass no silver
and allot of the things are not "suposed" to be worn outside of the uniform. and we marines tend to take the EGA
(Eagle Globe And Anchor) fairly serious and don't like it to be worn in a maner that may disrespect it. Not that wearing with a kilt is bad but change is hard to handle.
