Navy Times recently reported that the 47 additional ships had been added to the list of those whose crews may have been exposed to Agent Orange during the Vietnam war.
Looking into this a little further, it appears that all Coast Guard vessels that participated (WAK, WHECs, WLBs, WPBs) are included in the list. Go here for more information. Any Vets who set foot in country are also presumed to have been exposed.
“Veterans must meet VA’s criteria for service in Vietnam, which includes aboard boats on the inland waterways or brief visits ashore, to be presumed to have been exposed to herbicides.
“Veterans who qualify for presumption of herbicide exposure are not required to show they were exposed to Agent Orange or other herbicides when seeking VA compensation for diseases related to Agent Orange exposure.”
