On the contrary the Anzac will stay. Their turn may be combined with the UK in the glob game I don’t know. The set up for the glob game will be the same with some minor adjustments. One of those adjustments (from Larry) will be a few Anzac in Africa for the glob game that won’t be there in AA40E only. He posted that a few days ago. The Anzac IMO will be about 1/4 the size of the UK, making it more of a minor power in the glob game. I think the rest of the Commonwealth will be represented too. I think the India IC will stay, but might shrinking to a minor. There will most likely be an AB & NB in Eastern Canada (Quebec) and maybe even a minor IC, controlled by the UK. There could even be some thing in S Africa.
I still feel because the Anzac will be such a minor power (most likely controlled by the UK) that there should be some mechanic to allow them to perform joint attacks. I know that the US took control of most operations in the Pacific, so allowing the Anzac to attack with either the UK or US would be a step in the right direction IMO. Other wise just splitting them off from the UK could be more of a hindrance to the Brits.
