what about Cuber

Its probably a technicality, but if memory serves, the Soviets didn't actually get to finish completely installing the missiles there. They were close, but I don't think they were ever fully operational.

Actually they had smaller nukes that were in Cuba and could have been used to combat an invasion.

Also, the Soviet Union borders Eastern Europe the last time I checked a map. There was no need to deploy tactical nukes when they could have been deployed in an hour.
