Frontline has changed to four (4) classified objetices. The text on the Intelcom rule is still (copy/paste) singular, speaking of "the classified objective" so I assume we choose one of the four as our Intelcom. I think the text should read "chose one of the four classified objetives" to avoid confusion.
Given that the changes were probably largely inspired from this thread I can say that was the intent when I made the suggestion.
Another here to say thank you to @Triumph for this summary! This game is so complex, this kind of tracking of changes is really really helpful and important.
