Hans, best maps I have found are posted on this site. Look for post "Official Base Maps" which I have moved back toward the top so you should have to scroll far. I used these with my successful herbicide claim with the VA. Also search the internet for the Veterans benefits network Forum (on YUKU), other knowledgeable vets sharing their knowledge of claims. there is a section on Thailand claims. No sugar coating they tell you what you need to do. Do your research and submit a "Fully Developed Claim" every time you add info to your claim, it goes backwards and the time frame drags on. If you need help another let us know your email. LouB.
