Question:
How do I obtain a roster of my fellow Marines who served with me in Vietnam?
Jim's Reply:
You'll have to use the Internet to search for the info you're seeking. Go to Google search and enter the name of your unit. Once the results are returned, it's then time to refine your search. You can enter any names you may remember and so on.
There are a ton of commercial sites that promise you they'll do all this for you for a membership fee. Don't bite, all they do is set you up with spam emails.
The info you're seeking may or may not be out there. Records weren't computerized back then and paper records tend to disappear over time.
Good luck.
UPDATE:
Thanks to a reader of Jim's Mailbag, another resource has come to light that may help you find a roster of those you served with in Vietnam.
Go to this searchable database created by Texas Tech University to search for your unit, its unit diaries, and more. Specifically, the unit diaries should include personnel joining and leaving the unit, along with any casualties. The information is not limited to the Marines, though of course they are included.
Hope this helps!
