As you pointed out Flash, units that are mobilized in Bombay will represent both Indian and Anzac units which would most defiantly included Aussie air craft. I don’t see a problem with this historically. Larry didn’t give us some BS about Indian factories building these units, he explained it very well IMO (see below). This has always been his stand about ICs throughout (although this game doesn’t have ICs). They are staging points bring in fresh units through air, sea, or land (rail?).
Quote:
Britain may place newly purchased land and fighter units in India during the Mobilize New Units phase of the turn (Phase 4). These forces represent troops from India and the Pacific British Crown colonies and they are staging in Bombay
Game play wise it really depends on if there are restrictions to how many British (Commonwealth) units that can be mobilized in Bombay. It could be tied to the IPC value of Bombay which looks like 4 (which seems like a lot to be honest). It could also just be self governing to where if you over build in India to gain an advantage in the Middle East and Africa that it will cost you in Europe.
PS, as you also pointed out the Ottomans or US didn’t have the equipment they are allowed to mobilize either, but they got the stuff by some means. It was either supplied by their allies, or purchased somehow. You need to get over the image of these powers producing these units in their own factories, and see it for what it is. A central place to introduce new units to the game. This would include their own industrial means, purchasing from allies (sometimes even black marketed enemies), staging points for industry from their colonies, or simply pulling in all available resources from the surrounding region by air, ship, or rail.
