Or an American invasion map. The UK and Russia both lost to the axis powers. While fighting some smaller battles in Africa and the middle east, they now focus on taking over the Americas. With the only ally to be Argentina on the Americas mainland, they now face a coalition of the remaining American powers with the United States, Canada and Brazil as the most important ones.
COOL
A what if the Americans stayed out of the war, and the axis won scenario.
I think you should add cavalry because the British had a cavalry division at the start of the war. Also the ANZAC’s had cavalry divisions even though the did not use them in Gallopoli and will you include rules about terrain such as the hills in turkey that meant the ANZAC infantry became fodder. Also will there be sea units used for transportation? You could also create a tech that meant Art could fire poison rounds that decreased Inf def and also killed halve of Inf stack.
