LOL!
GDW's take on the AK invasion certainly didn't involve anybody taking the time to look at a terrain map of the area involved. The only Soviet options that ever made any sense was taking out either end of the pipeline, and the Soviet Pacific Fleet never had the power projection to actually try it. It would have been a Spetsnaz/Airborne show and would have been more of a raid than anything else, and it would have been more easily accompished by tossing a few dozen SSMs/ASMs into the area; or even just park a SSN or two with orders to sink tankers. From a story line, its intresting, but from a realistic approach, it would never have happened.
With the job of securing the pipeline, hunting down the Soviet recon/raiding party...I think the 6th LID would have been kept in AK, at least until the 47th ID was up to speed and deployed. Even then I can see 6th LID moved up to the north and west coasts with the 47th securing the major cities in the south. Can't say that I would agree with deploying a Marine Division, the situation in Korea would have almost certainly required their deployment there. Most likely one of the NG Infantry Brigades could be moved into the state, if needed.
Korea is the big question mark of the game...from the Vehicle Guides we know that the US units committed took brutal losses. But never so much of a hint of canon material to explain what happened. Someday, in my overflowing free time, have to sit down and start writing something....
