Nigeglib,
I understand your question totally and as you have probably gathered I echoe your concerns, but sadly I have absolutely no idea of what the JPR arrangements are for this theatre of operations and to be truthful if I did I most certainly wouldn't disclose them.
So not wishing to let anyone get off the hook for not resourcing properly, I can wholly understand why you were given the stonewalling.
However, if you lobby someone that has the right security classification and trust them to do your business, then you may have better results.
