Hi Rob: Thanks for your feedback and acknowledgemernt. i appreciate your comments. There were six defoliants designated by different stripes painted on the barrels that included Blue, White and of course the most toxic, Agent Orange. I write about exposure and the what happened to my unit and I on the battlefields, as well a pinpoint the cause and effect of the war. I invite you to stand with me on Nov 11, Veteran's Day to particpate in launch of Vietnam Uncensored. The book will be discounted by 50% and I have pledged all net proceeds to the help veterans in need through the Kaufman Fund. Find out more at https://vietnamjerry.com. Hope I can count on your inclusion in this worthy project. Thanks.
