John, would be happy to try and help. I need more info to compose a letter. please contact me at labousq@verizon.net and we'll see what we came come up with. Just a note, I never did any augmentation guard duty while at Takhli (1966), do you have any proof (orders etc.) that you did? Saying it is one thing, proving it to the VA's satisfaction is another. Happy to help if I can. LouB
