I think it would be really sweet to have a cold war campaign, maybe going thought the whole cold war wouldn't work because of how many units would be need to be made. But I think a 50s (about 1955) cold war campaign would be sweet (hold on, this isn't really about campaigns). It would be an event that didn't happen against the U.S. and Russian.
(Here is were the addon part comes in) The U.S. changed there look after WW2, as did the Russians- although they did have some same units. I have seen a 50s U.S. plane, but needs something more then machine guns. I even think they U.S. had the M-16 (the Vietnam style) at the near end of the Korean War - I saw a picture... and pictures don't lie... although that picture could have been in the wrong spot.
I would like everything to tanks to planes to helicopters (I got the MASH style chopper) to infantry. Countries like Russia, the U.S., China, and some UN country troops... and heck, maybe North and South Korea troops too. You editor guys now what to do.
