I have not yet reached the end of 1942 and the historic time for the US invasion of North Africa and Operation Torch, but I'd like to be prepared. So, is there some kind of coordination event with the UK, or do I just land and attack and hope the Brits are there? Same question goes for Operation Husky and Operation Avalanche.

Land and pray. The AI isn't "that" good.

Though it's getting better - hopefully in a few versions time it will truly be a beast to be reckoned with.
