Answer: No. Any veteran who served in Southeast Asia can order and wear this ring.
Question: I did not serve in the military, however, I lost a loved one in Vietnam. Is it okay for me to order and wear this ring in their honor?
Answer: Yes. The most important feature of this ring is to silently honor those veterans who served in Southeast Asia . When ordering in someone's memory, you would order the non-labeled type, that is one without the branch of military engraved on it.
Remember, one glance at this ring will immediately identify the wearer as one who served in Southeast Asia or one who is honoring the memory of a loved one. Pass it on lest we never forget.
