A different Fourteenth Army if the Pacific war came first

Would a Fourteenth Army formed for this earlier Pacific war contain more British troops?

Probably; without the same prior commitments elsewhere, its British share might rise from about fifteen per cent to roughly half.

The historical Fourteenth Army contained a relatively small proportion of British-born troops because Britain was also committed in Europe, North Africa, Iran, Iraq, and the wider Middle East. If the Pacific war came first, those competing demands would be different. An analogous formation might still emerge, with its British component rising from roughly fifteen per cent to about half. The figure is a scenario estimate rather than a proposed exact order of battle. Its value lies in showing how the sequence of wars changes coalition force composition.
