The DOD has not confirmed spraying or usage of AO at that site- however-
you could access the DOD report on line at
http://www1.va/gov/agentorange/docs/Report..._of_Vietnam.pdf.
You might have been in one of the other areas mentioned in the report such as Fort Drum (testing)1959 or Fort Richie MD Testing 1963 etc.
Even if you were at any of the locales mentioned in this report -you must still support the claim with direct evidence of exposure to the AO. This could involve perimeter/guard duty of the AO was sprayed on the perimeter or handling of the AO barrels. These claims also might need strong buddy statements in support of the usage of the AO.
We have member here who I know well and who proved he was exposed to AO while during perimeter duty in Thailand.
I know of a vet awarded AO for duties in Alaska and there are other vets who have succeeded in this type of claim.
It took them all a lot of work and research.
You could access your unit on line-most units have web sites- to see if anyone else has filed a claim due to AO at Ft Lewis when you were there.
The Thailand vet actually got some of the info he needed from FOIAs to DOD.His MOS put him on the perimeters and DOD confirmed the perimeters of his base had been sprayed during certain dates.
The info on the internet regarding AO is far more extensive then any libraries have.
I dont know if there are AO researchers out there-
does your MOS suggest you would have been in areas they tested or sprayed? Or did your MOS involve transport and storage of the AO barrels?
I assume you have disability on the AO list- have you searched your SMRS to see if you can file for direct SC as well as presumptive to AO?
