Having mentioned the common trope of the Soviet Union launching an amphibious attack on Iceland popularized in Red Storm Rising, I was playing another Command scenario set with that premise when I saw something.
I can see the reasons for a Soviet invasion of Iceland being so common in potboiler fiction, regardless of the real (im)plausibility. Attacking Iceland is dramatic by itself. To have the invasion initially succeed also gives the “heel” (wrestling villain) the credibility they need to be more than a “jobber” (constant loser) so that the “face” (hero) can have an earned victory.
(Sorry, VGCW has inserted pro wrestling terms into me 😀 ).
But as I played, I saw the gameplay advantages an Iceland base gives. It makes sending aircraft to the North Atlantic far easier than it would be if the AI had to stage them from Kola, even with the refueling changes.
So at least for Command, gameplay reasons may be another (sometimes unintentional) reason for the popularity of the Soviets taking Iceland.
