I agree zuluhour. At Noumea/Koumac, there isn't much I can do. Koumac has over 50,000 men there, about 3 divisions. I have 2 divisions at Noumea. He also has more than a division at La Foa. I could bring in 2 more divisions and still not take Koumac. At Nadi/Suva, however, I have an opportunity. I'm bringing in the rest of a Marine division now. And I'm going to bring in 2 divisions from Australia. That will be enough to eliminate the enemy at Nadi, which would be a nice result. All of this assumes that KB leaves the area long enough, but that may happen with what's about to happen up north.
My current long-range plan for Koumac is to isolate it, instead of taking it. Aurorus will probably pull out troops before this can happen, but I think I can force this evacuation with a plan of isolation. At some point, if there's a drawdown at Koumac, an assault could become possible.
Still, the plan is defend and delay. Except for what's about to happen up north, where the plan is...well, we'll see soon.
