You guys looking for information, maps, documents on herbicides/AO for a exposure claim really need to look at the stuff posted in the files and photos section of the Thailand Laos and Cambodia Veterans FB Group. A lot of very good stuff there that you can download and use in your claim process. Do yourself a favor and check it out. If you don't have a facebook account then create one. It's free and easy. Just create a very simple bare bones account. That's all you need. Then you can get at a lot of good information at the group page mentioned above as well as others.
