In my opinon, if there is a connection, why not? If it's worn with respect. I wear it because I am a Marine...and I am very proud of that fact.. I also know there are those who cannot wear it anymore, and if a family member wears it to keep a Marines memory alive.. I am all for it. I am, and I would say every other Marine on this forum, more protective about the Eagle, Globe, and Anchor.. Or the title of Marine.. Those items we earned.. the Leatherneck tartan is just a bonus..
