So far haven't figured out much.  Except Moscow is a pretty hard target.

It seems to me that hitting the opponent's population centers sends them into Armageddon mode, i.e. he's allowed to launch every warhead in his arsenal. Presumably the trick is to make it impossible for the other guy to hit back at you. I've tried several strategies, such as gunning entirely for command-and-control targets (on the grounds that you can't order missile launches if your all of your communications are down) and various counterforce schemes. No use.

The A.I. for either side keeps going for your BMEWS and other early warning targets early in the first volley. I'm not sure why.

try tit for tat?

TbV, did you make any progress with BRD? I never was successful with that game: I suspect the ending was never finished.  It was also frustrating that there was never any "See All" cheat so that you could figure out what the heck was actually going on. After a few hours, your commo is so degraded, you have no idea what's been launched, what's hit, etc. It would be fun to have this game updated with a better interface.....

I haven't fiddled with it for a long time. The game is so abstruse, thanks to the lack of documentation, that it deserves its own wiki. (Maybe there's an idea there.) I did go back a few months ago to record the CEP and launch times of each USSR weapon system (6 hours for the SS-N-18s? Meshugah!) as well as making a map of the various US military targets... But that's it. I haven't tried any more approaches to the scenario.
