hi everyone...

i was given a dog tag from a friend who served in Vietnam from Feb 1967 to April 1968. he was assigned Foxtrot 2nd Battalion, 1st Marines (1st MarDiv)...

having served in the Air Force (albeit close to 20 years later than him) im familiar with most of the notations on the tag...

i have a question though. after USMC, about 4 spaces there is a solitary "M"...

i understand the name, "O" blood type, service number (not SSN), branch of service, and religious preference but that "M" has me baffled. the only thing i could think of is "Male" but i dont think thats correct...


are there any Vietnam Marine vets here (lol... dumb question im sure) that could fill me in?
