I would be surprised if this were publicly documented anywhere. It's not a secret AFAIK just not common knowledge. I knew several people involved in these exercises. They are no longer with us and it was not specifically about decrypting data. This was about intercepting communications via scrambled radio, RF signals and sub-carriers, spread spectrum radio, electronic typewriters in hardened shielded vaults, lights. So your only link I suppose is me. There are probably a few other old timers out here with a similar circle of friends and associates. I'm sure nowadays it is about intercepting keys, custom ciphers, etc... I'm just not in those circles any more. And those things are usually stolen and/or blackmailed out of people, almost nothing technical about it. In my time blackmailing people was about gay bars. We had cameras monitoring all the local gay bars. Nowadays it's probably more along the line of Epstein/Maxwell and related events. I do not know what else would be considered highly taboo these days. Is anything even taboo any more? Prior to being in the military I always assumed the US and the Soviet Union were enemies, as in everyone hated everyone. It turned out that was incredibly far far from the truth. We played a lot of friendly games and also exchanged a lot of equipment. We acquired numerous 15KW transmitter tubes from them for example and that conversation started with "Why is the ceramic pink?" and my follow-on question was "We bought them from ... who??"
