Don't expect a quick or easy win on this map. The circular nature of the command posts ensures that even when the odds are against your enemy, they'll still manage to capture posts while you're on the other side of the map (and while there are 2 or 3 of your troops just sitting inside a tank right beside them). I do advocate trying to maintain control of the center, otherwise the enemy will quickly mobilize in all directions as their units spawn. Unlike many mods for BFII, the vanilla game's AI is usually good about defending command posts, but maybe not so much on this map.
