The best they can come up with is that the required vaccinations in the Marines to go to Viet Nam and something they can be exposed to caused MS. Both of my Brothers that were in the Marines and served in Viet Nam/Japan/Asia got MS. Understand 80% of Viet Nam Vets that are disabled have MS. And that's NOT counting the agent orange stuff that caused cancer. And my twp brothers had different fathers as well.

Younger brother was crew chief on a Chinook and was in the thick of it. He came home with MS.
Older brother was radar operator on an F4 phantom and got MS After going back to the area years later as a missionary.
When in the Jet group he mostly stayed on the big bases and on carriers and didn't get into the villages etc.
Younger brother was taking stuff to and from the villages all the time he was there.
