In regards to armour, it should be recognized that it is not as straightforward as it seems. It is a bit more then shipping tanks over as soon as they are produced, the entire process is a bit more complicated then that.
Since this TL has been logistics heavy, the better question would be, can Malaya support armoured units?
Is there a RAC depot, with trained personnel, and all the tools, spares and materials needed in sufficient quantaties?
Looking at the supply chain, where exactly do the resources needed for its operation come from, can any of the required materials be sourced locally?
And then, the question will be raised, why are tanks being sent to Malaya, when North Africa is screaming for tanks, and now you have to support the Commies, who have managed to lose how many thousands of tanks?
But hey, there is quite a few of
these around, so are we to see the unthinkable?
