Muff, I'm with you.
Sam has represented what I would call the exception to the rule. Perhaps because agent orange exposure is a given if you have proof of time in an area now included for probable AO exposure and display listed symptoms from exposure. Plus, Sam has great communication skills.
Had I not saved every possible piece of paperwork with my name on it, and had I not had excellent representation from the DAV. The VA would have dismissed my claim in a heartbeat. In fact they tried, had it not been for the records I kept (tdy orders, combat pay, travel vouchers, etc;(thanks Mom), and although incomplete, medical records from the records center) the VA would have turned me away for lack of proof to substantiate my claim. Meaning they may have believed what I presented as true or actual, they(the VA) will not approve any claim without supporting documentation and their doctors diagnosis must also agree with the claimant's claim. For me it was a process that took over two years, beginning to end, and while I may have been able to do it own my own. I'm glad I didn't try.
Vets, if you know or feel you have a justifiable claim for a service connected disability. It is your obligation to prove it, in most instances. Whether you look to the DAV, VFW, Purple Heart, or any other veterans service support group for assistance . In the end the representative who takes your case is a very important part of the process. They need to be well trained and not overwhelmed with cases. I have dealt with two of the groups I mentioned and the DAV as an organization is as top notch as you get.
Hope this helps someone.
