Coincidentally enough, the one nuke target in Alaska just happens to be Elmensdorf AFB (from the v2.2 rules, I don't use the timeline, I just use the nuke targets). Which just happens to be abutting Anchorage. Which happens to be the city the 2nd Infantry Brigade is protecting in July 1997.
Maybe instead of abandoning Anchorage, some units manage to hold out 4 months instead?
