Weapon employment and publicly available documents

I read a few times already that ED (and probably also the 3rd party module developers) only use publicly available sources for creating the aircraft modules and weapons systems in the simulation. I was wondering what those documents might be and where we as sim users could read those.

As far as I can see, almost all flight manuals are classified or have export restrictions. So those should be off limits I guess. Another option is of course to use video footage found on youtube and elsewhere, but this shows only a very small aspect and is in no way enough to create a simulation thereof. Asking/interviewing (ex-)pilots is another option, but I'm not sure how much those pilots would be able to share.

In regards to export restricted documents, it might be ok (I'm not a legal expert here) that someone reads those documents in the US and writes a completely new document based on that information which can be shared with the sim developers in another county. However, I'm pretty sure that this method would not be possible with - say -34 documents.

As I said, I would only be interested in the publicly available documents. Wouldn't it be ok, to have links to those in the DCS forum for each module?
