Omg I missed a lot when I was away. To the person who asked, yes you can play Cuba having its revolution since that actually happened. However, you could also choose for it not to have its revolution or have it fail. It's up to you since it's post-1950. For example, I'm East Germany and depending on how things play out maybe the wall won't even end up going up. 

As for the other question, for now I'd like if people just count their active troops. Reserves are not as relevant right now.
