We played Team Yankee on a double size board with 200 points per side to see what would happen. Mutual obliteration is what happened!
Both sides - Soviets vs Americans - went heavy on air assets, which skewed the game somewhat. Initially the American air arm ran amok amongst the Soviet armour, knocking out a whole company of T64s by the second turn.
The Soviet reserves arrived first, in the form of some T80s which, along with some BMP1s, managed to flank their opponent, enabling them to take out the American Chaparral air defence systems. Also, eventually the Russian Gophers, Shilkas and Gremlin missiles managed to weaken the US helicopter force (helped by the fact that the Warthogs failed to show up for a few turns). The 'Krokodils' (Hinds) then made an appearance, taking out a couple of M1A1HCs, but by that time, there weren't that many ground forces left on the table.
In the end we gave a 'winning draw' to the Americans.
I'm not sure we would play 'big game' Team Yankee again with just two players (as it was a bit of a slog), and we would probably seek to introduce a few other special rules to allow for the larger spaces involved - along with limiting the amount of air assets allowed.
