How do the Vietnam veterans get treated?

Answer 1

I wish I knew what you meant by "treated?" If wounded, naturally they may have initially been treated by a fellow Soldier or Marine and/or a Medic or a Navy Corpsman. If the wound/s were serious, hopefully they would be choppered out to a Hospital.

If you mean being "treated" upon arriving home by U.S. citizens , well, that's a different story. In many cases VN Vets were treated very badly in public areas such as airports by anti-war individuals or groups. That also depended a lot of what part of the Country they were in. San Francisco and Berkeley CA would probably be the worst place to be if you wore any type of a U.S. Military uniform.

If you mean "treated" for wounds upon arriving back to the U.S. then they would have been treated medically at a VA Hospital.
