The Veteran's service connection claim for Chronic Lymphocytic Leukemia (CLL) due to herbicide exposure is granted. The Board found the Veteran was exposed to herbicides during his service at Udorn RTAFB in Thailand, which is presumed to be associated with CLL.
The deciding factor: The Board found the Veteran's lay statements and testimony credible, establishing he was physically present on the perimeter of Udorn RTAFB where herbicide agents were used during his Vietnam-era service.
