I think it comes from the fact that the second Soviet mission in MO is about clearing the Alcatraz for the PsiCorps specifically, asked by Yuri himself. Since that is a mission with the fake-Yuri voice actor, it is a most memorable mission.
Well sure, but from the story standpoint, it would seem like the first place the Soviets would go to. I mean, their top commander was there, seeing that PsiCorps is doing a project there, I'd assume that he'd say something about that.
Damn, ninja'd. I was going to say that myself.
Anyways, though, it is a valid point: since Alcatraz Island was specifically requested by Yuri, then it is natural that the Soviets would begin their investigation there first.
Thus, we will either get a Soviet mission where we attack Alcatraz Island, or we get an Epsilon mission where we have to defend it from the incoming Soviets. The Allies are not invited because they are currently nowhere close to San Fransisco.
