As a brown water sailor I have never figured out how a blue water sailor steaming on the gun line could be exposed to agent orange.
Could such claims be nothing more than a hustle to game the system?
On the off chance that you are serious about your question, I suggest that you follow this link:
Read the information relating to Water Distillation Issues and the Austrailian / New Zealand Navy Vietnam Veterans reports. Or, read or listen to the "Haas vs. Nicholson" Oral Arguments before the 12th Circuit Court.
Educate yourself on the subject, then get back to me.
