What kind of questions should one ask. I know that one should have a humble approach but how should one start? How do these veteran organisations work?

I assume you are talking about the German organisations, right?

Personally I don't have too much experience with them, but I would assume that the more information you give the more receptive they will be; I mean, if you want to contact vets because of a serious research project and you are able to convey what you know and how interviewing vets or whatever would fit in with your project, they will be more inclined to offer assistance than to some-one who 'just wants to write to veterans'....

Yes, I think that I'd write mostly to german veterans since that is what I'm researching. Thanks for the tip, it was a good thing to point out.
