Do you have all of this in writing? telling you so over the phone is not evidence or by word of mouth , you should have orders and orders about what you just mention about the 4 officer’s , morning reports unit reports ect,,ect,, they can come back and say we don’t know who told you this? ect,,ect,, you need confirmation in writing. Letters or emails from anyone of those 4 officer’s will be good…we never had emails back in 1971 so you would need to contact these officer’s
As for as being exposed to A.O. If you were boots on the ground in Vietnam then yes you are considered to be exposed…some areas of Nam worse than others but the point is you were exposed to the Air in Vietnam. VA Uses the Presumption of a Condition caused /related to A.O. OFF THE A.O. Presumption List.
your DD 214 Should have your Vietnam service on it and your CIB Ribbons Unit Awards ,Certifications ect,,,ect,, & MOS and the location of your Vietnam unit you served with this DD-214 is a very Important document.
About the only other Advise I can give you is contact someone like Alex Graham (Asknod) or maybe an experienced VA Attorney to help you with this and your claim…I use to use the DAV but their a little on the lazy side and I ended up working my claim by myself along with some great hadit members years ago.
We older Vietnam Veterans need to stick to gather I am a 1969-71- Vietnam combat Veteran as well As member Gastone 1968-69 I believe.
And broncovet too!
