I just received this from an old Air America buddy, if you think this effects you, check it out.

VA Compensation & Pension Service Bulletin May 2010

After reviewing documents related to herbicide use in Vietnam and Thailand, C&P Service has determined that there was significant use of herbicides on the fenced in perimeters of military bases in Thailand intended to eliminate vegetation and ground cover for base security purposes. Evidence of this can be found in a declassified Vietnam era Department of Defense (DoD) document titled Project CHECO Southeast Asia Report: Base Defense in Thailand. Therefore, when herbicide related claims from Veterans with Thailand service are received, RO personnel should now evaluate the treatment and personnel records to determine whether the Veteran’s service activities involved duty on or near the perimeter of the military base where the Veteran was stationed.

DoD has provided information that commercial herbicides, rather than tactical herbicides, were used within the confines of Thailand bases to control weeds. These commercial herbicides have been, and continue to be, used on all military bases worldwide. They do not fall under the VA regulations governing exposure to tactical herbicides such as Agent Orange. However, there is some evidence that the herbicides used on the Thailand base perimeters may have been either tactical, procured from Vietnam, or a commercial variant of much greater strength and with characteristics of tactical herbicides. Therefore, C&P Service has determined that a special consideration of herbicide exposure on a facts found or direct basis should be extended to those Veterans whose duties placed them on or near the perimeters of Thailand military bases. This allows for presumptive service connection of the diseases associated with herbicide exposure.

The majority of troops in Thailand during the Vietnam era were stationed at the Royal Thai Air Force Bases of U-Tapao, Ubon, Nakhon Phanom, Udorn, Takhli, Korat, and Don Muang. If a US Air Force Veteran served on one of these air bases as a security policeman, security patrol dog handler, member of a security police squadron, or otherwise served near the air base perimeter, as shown by MOS (military occupational specialty), performance evaluations, or other credible evidence, then herbicide exposure should be acknowledged on a facts found or direct basis. However, this applies only during the Vietnam era, from February 28, 1961 to May 7, 1975.

Along with air bases, there were some small Army installations established in Thailand during this period, which may also have used perimeter herbicides in the same manner as the air bases. Therefore, if a US Army Veteran claims a disability based on herbicide exposure and the Veteran was a member of a military police (MP) unit or was assigned an MP MOS and states that his duty placed him at or near the base perimeter, then herbicide exposure on a facts found or direct basis should be acknowledged for this Veteran. The difference in approach for US Army Veterans is based on the fact that some MPs had criminal investigation duties rather than base security duties. Therefore, the Veteran’s lay statement is required to establish security duty on the base perimeter. This also applies to US Army personnel who served on air bases in Thailand. During the early years of the war in Vietnam, before Air Force security units were fully established on air bases in Thailand, US Army personnel may have provided perimeter security. In such cases, if the Veteran provides a lay statement that he was involved with perimeter security duty and there is additional credible evidence supporting this statement, then herbicide exposure on a facts found or direct basis can be acknowledged for this Veteran.
Evaluation and adjudication of the cases described above can now be conducted by RO personnel without input from the C&P Service Agent Orange Mailbox.

These instructions replace those provided in the August 2009 C&P service Bulletin. In summary, no herbicide related claim from a Thailand Veteran should be sent to the C&P Service Agent Orange Mailbox. If evidence shows that the Veteran performed duties along the military base perimeter, ROs should acknowledge herbicide exposure on a facts found or direct basis. If the available evidence does not show service along the base perimeter and does not otherwise indicate exposure to tactical herbicides, place the memorandum for the record from M21-1MR IV.ii.2.C.10.q in the claims file and send a request for information to JSRRC.

Taxonomy upgrade extras: 

I am at the point of sheer aggravation dealing with the VA, and requesting your advice. Nov. 2010 first VA claim was filed after going downhill medically & urging by family after the May 2010 C&P bulletin. They separated IHD claim from other claims & issued denial date of 2/14/2012. Reason for denial..evidence shows service during Vietnam era @ Takhli RTAFB, diagnosis of CAD, but objective evidence fails to show confirmed exposure to AO. At this time, VA regs do not allow concession of exposure to AO for (MOS 42153) Aerospace Ground Equipment Repairman Thailand, and personnel records do not show SP or dog handler. I worked on the flightline,servicing planes & aircraft equipment on/or near perimeter, 12-16 hrs a day from 7/69-7/70. I did file for Herbicide Exposure & have not heard a word about the other claims...about 400+ days now sitting in the St Pete RO. Please advise with your thoughts & opinions if I qualify or not for exposure.

Appeal and seek a lawyer. Use map of Takhli from many to choose. One may be at my site.

Hello bostonpatriot,
I was at Takhli july 69-july 70 and i worked in the age shop night shift. i worked mainly on bomb lifts. I am 50%service connected. 40% on hearing and 10% tinnitus. I applied for Agent Orange exposure for Ishemic Heart disease and DM 2. it was denied in feb 2012. I appealed apr 2010 and I still am waiting.
you mentioned in your post that afsc 42153 did not show exposure to AO. how do you know this?
Please get in touch with me at and lets see if we may have been working together.

Please assist with info contained in my recent post with same subject line. Thanks Rick

With all of the herbicides applied in Thailand, has anyone seen where someone that did the applications came forward and told of the locations sprayed? Someone had to have done the applications. Have they all died off. Am I the only one that thinks this is odd?

I was at U-Tapao OCT 1973 to August 1974 I don't know about the perimeter. However the end of Oct/ Nov 1973 I witnessed them spray the flight line. There was a SSGT steward that was with me at the time would like to find him. I have Parkinson's, and more. I have been fighting the VA for over two years. Anything I can do to help you do not hesitate, willing to help. J. Michael My E-mail is

How can I prove the association of daily flightline duty(1969-70) to the base perimeter for herbicide exposure? Received an IHD denial from the VA dated 2/2012, stating that" objective evidence fails to show confirmed exposure to AO. At this time, VA regulations do not allow concession of exposure to AO for MOS 42153 Aerospace Ground Equipment Repairman in Thailand, and your personnel records do not show security police or dog handler." What MOS' qualify for concession of exposure?? And how do I find out? All my detailed mailings apparently have gone unreviewed thru the years at the VA regional office.
I filed the claim for Herbicide Exposure not AO. VA has had several inquiries to JSRRC & keeps delaying & reverting to claim development stage for several years now. Words are inadequate to thank you for all your research on Thailand herbicide spraying & presenting the evidence of the secret Checo Report, etc., to help all the veterans who suffer from the effects of the herbicide spraying.

I am the surviving spouse of Jon Hirsch who served @ U-Tapao from 12/70 -2/71. He passed from 2 of the AO cancers CLL & Non Hodgkins Lymphoma in 93. I am having trouble trying to connect it to his service & have had my claim denied.
Do you have any suggestions?
Hope you are doing well.


DLH....Hi Nancy, so very sorry about your husband. Did you have a VSO (veteran service officer) helping you? Find someone like DAV that is willing to help. Right now, for Thailand vets the VA is saying they had to be with the security police duties to qualify. Don't let that discourage you. But get all the med records you can from in service, and after. Go to and get a lot of info. Hope this helps some..good luck with your claim...


Last month I submitted a comment and a photo of Detachment B, 7th Radio Research Field Station taken in 1971 at T-11 (Chieng Mai). My comment was lost when I attached the picture. Vets would be advised to look at that picture as it represents what a lot of us saw but didn't understand when we were over there. Vegetation grew at a phenomenal rate and for there to be a bare expanse like this anywhere-be it at Det. B, Udorn, or Long Tieng (Lima Site 20 Alternate) indicates a lot of herbicide. VA and the military say it was non-tactical as in Roundup. I know differently. There were 55 gallon barrels of Orange and Blue lying right beside the Air Operations Center at Long Tieng and a PC-6C AirAm Porter outfitted with tanks that flew out of L-08 Wattey (Vientiane). They refueled and reloaded the herbicides there (Long Tieng) frequently. I have pictures on approach to Alternate showing the extent of herbicide usage around the runway and aprons. I personally witnessed young (8-10 year olds)Hmong kids who guarded the perimeter using bleach bottle scoops w/ AO and AB (undiluted) to abate the foliage. At Udorn, my barracks (the new "barns" in May 70) were less than 60 feet from the perimeter. The laterite roadway was the only thing in between us and the fence. Nothing grew there-ever. The Thai lunch vendors who sold through the fence to our hootch girls cooked and ate right in the middle of it. I spent 30 days in Saigon before I was sent up country. That's hardly any exposure to AO there. Nevertheless I have Porphyria Cutanea Tarda and was coughing up blood when I came back in 72 after two years in Laos and Thailand. Don't let the VA isolate compensation to just the Air Policemen and Army MPs who were on the perimeter. Most of us were assigned to Augmentation duty for a month when we got to Udorn because they didn't have enough to guard the perimeter. I can't speak for other bases. Nevertheless at Udorn you didn't have to work the perimeter. It was right there adjacent to your barracks. Any of you who file for AO disease would do well to get buddy letters on this. In the Udorn case, you don't need to know the person who writes it. It's sufficient to say that anyone who can document they were stationed there PCS for a year is capable of testifying about the proximity of the barracks to the perimeter and thus the obvious lack of foliage in that area.
Check this out if you have questions about it-- Look at the pictures in the background-nothing but dead grass. Look at the approach to NKP and it was a wasteland of bare fields for a good reason. I have more recent pictures of NKP and they all show lots of green. We all know that the military was in the habit of stocking one type of most things. VA is asking us to believe they used a non-tactical herbicide in Thailand and AO magically fell to the ground before it crossed the Mekong from Savannakhet,Laos?
For those of you thinking about filing a VA claim, I suggest you read this book-- It will help a lot of you when file for anything-not just AO claims.

I was stationed at Korat RTAB in 1973 with the 354th TFW Composite, comprised of units from Myrtle Beach AFB, SC, England AFB, LA and Davis-Monthan AFB, NM. The unit was armed with A-7 D Corsairs for SAR missions looking for downed pilots. So far, the VA has refused my claim for presumptive service in Thailand because there is no AFSC code to support my work of precense along the perimeter. In addition, most of our troops were billeted on Camp Friendship fenceline. I also was used as an augmentee for guard and perimeter patrol duty and my place of duty was on the fenceline at Korat near the airfield.

I have been diagnosed with diabetes II, iscemic heart disease, coronay artery disease , hypertension by civilian doctors and VA AO Registry doctors. I recently underwent an cardiac ablasion to stop Atrial Fibrulation (Afib). These disease were documented in a summary letter from the examining VA doctor who conducted the labs tests and questionaire. The VA RO said I needed additional evidence, which I documented and sent evidence from my civilian doctors. I guess I need more evidence but need additional information fro other vets who were there.

I am looking for evidence of our units presence being billeted at Camp Frienship, photos, other people who would provide buddy letters, maps, etc.

Any guidance or assistance that you could provide would be helpful.

Please see for augmentees, for specifics on Korat.

The claim is not presumptive, it is a direct exposure case, in which you should show exposure.

Some other related documents may be found here:

My name is Gordon Lewis. I was on a 180 day TDY to Korat from Jan73 to Jun73 from DMAFB,AZ in support of the A7-Ds from Myrtle Beach AFB. Myself and others were billeted on Camp Friendship along the south fenceline. Was this the south perimeter? I thought I remember it had one of those guard towers but not sure. I am a Aircraft Mechanic AFSC 431X1C. Trying to remember things back then is very hard. I also have diabetes type 2, hypertension,and asthma. I am trying to gather evidence for my claim also just started.I was looking at a map of Korat RTAFB on the perimeter & the drift zones and it did cover areas that I worked in ie. EOR & Trim Pad. Please If I can be of any help to you. contact me at:

Hi everyone!

I am looking for someone who may have served with my Daddy..John E. Odom He worked in the FMS and A&E at Takhli from 67-68... He had Parkinson's, prostate cancer and heart disease.

If I could find a Veteran who may have known him then, I may be able to prove herbicide exposure. He went to Vietnam too but after two years of hard work and researching his files from ST. Louis archives , I can't prove his boots on ground..

The claim was denied..

Thank you all for reading my post..

Susie, proud daughter of a Veteran

Susie, proud daughter of a Veteran

I am helping a friend whose father was at NKP in 1969....his MOS was Wireman and TelophoneiInstaller Repairman..he was going back and forth between VietNam and NKP but we can't establish said because of his high security clearance. VA is denying based on this and also is no precedent that Wireman duties were perimeter although vet says he did all his work on perimeter at night reinstalling cut lines. Can you suggest anything that might help?

I am looking for info about the location of the 4258th AGE "shop" on the bomber side in the earliest days of that operation. I twisted wrenches in that open air site from the time the bomber side of the base opened through June 68.

I'm needing this info to help me establish a VA claim. If anyone has photos that might include our AGE gear, refueling tank truck, etc., I would appreciate hearing from you. Even if you don't have photos, I'd like to hear your description and recollections of it. I posted a photo in the Aviation section of the Images section of this website. is my email address.

Thanks for you help.

DLH Hi John, my husband was there 1972-1973. We are also in the process of a VA claim. So we do understand what you are going thru. It is frustrating, but don't give up. Anyway, if you go on google maps and type UTapao, Thailand 1967, you can pull up an aerial map. Then you can zoom in on it to see more detail. Best of Luck to you....


I was there same time working in A&E supply point. I have a claim for heart disease been waiting since last August. Have you had any luck with your claim?

Those who worked on perimeter security...

Thailand-Ubon RTAFB

I did work on the base perimeter security systems both for the base and the other facilities that were associated with it. I now have major health issues, including heart problems, and cancer. I'm looking towards disability and wonder if anyone has been that route and can offer advice?


My name is Peter, and I'm never going to grow up.

My name is Peter, and I'm never going to grow up.

In 1967 I was at Utapao and our radio site was a remote hill top off base with the radio equipment and a generator. We usually had a couple of radio repairmen and a meshanic to take care of the generator. How do I find out if agent orange was used at this remote site to keep the vegetation down? I was with the 1985 Comm Sq.

Go to This link will show the bases where agent orange was used. Also, remember that if you can speak with the men you were stationed with, especially officers that had knowledge of agent orange being sprayed, you can use that as evidence, which the va cannot discount. Also, you may want to check out a book I wrote (hope its cool to post this here) that may give you ideas for helping your claim.

I was at camp Same Son 68-69 work in the motor pool.and became NCO of POL .My name is Seth Ridner .I have diabetes type 2 .enlarged prostate.and has of 10-17-14 heart a fib. I remember spraying of the perimeter of our base three times and fog sprayed all the time in our hootches all the time .I pulled guard duty three times on the perimeter of Utapao air base and it was sprayed.with herbicide.i went to all the camps in Thailand .YES HERBICIDE WAS SPRAYED ON ALL PERIMETER AND ON US FROM MIST WHEN WORKING NEAR THE PERIMETER.I WITNESSED AND STAND BY OTHERS WHO WITNESSED .SETH RIDNER SP/4 COD.538TH ENG.
