X Corps when it arrives has US Tanks as it was organised on US Lines irt has 2 Armoured Bdes - 4th and 9th because that what my source indicated were the X Corps Armoured element each one has 54 Chaffees and 104 Shermans
Happy to be corrected if you have a source that can give better data.
As its one of the never weres I went with a policy of giving X Corps US Equipment
And, for AE, that is the correct policy.
In 1945 MacArthur was adamant that all forces participating in Operation Downfall (the invasion of Japan) be organized and equipped on US lines.
Apart from not wanting to share the glory, MacArthur had valid logistical reasons for demanding this. The Sea LOC for Downfall was to go direct from San Francisco to Japan. There was not enough shipping available to support separate Sea LOCs for Commonwealth forces. By the early Summer of 1945 the British and Canadians had agreed to these conditions. The Canadian 6th division was in the US, learning US equipment and organization, when the war ended.
FWIW, the Australians were still holding out -- they agreed to use US equipment and eat US rations (a major concession, IMHO) but wanted to use their own weapons. But since they couldn't establish a separate LOC, they were unlikely to win the arguement.
