There are a lot of Vietnam veterans who have been in places such as Laos, Cambodia, South China, Burma and other areas during their time in service in that arena and the guvmint does not wish to admit it. The time they spent there is not reflected on their paperwork; and they have not been paid for their time there. Some have been visited by, as one vet put it, "men in trenchcoats" who told these vets to say nothing about their time in service there.
These veterans should be getting all the benefits due them.
The Veterans Administration needs to be cleaned up; it is highly corrupt.
