Using Midway as an example…
That 1 INF also represents, in addition to actually INF soldiers:
Artillery, a small number of aricraft, support and radar instalations, mines, barbed wire and other fortifications.
When/If the INF is move from Midway via a TRN, the TRN can be assumed to have additional reinforcing personnel on board (if advancing to attack) to bring it up to offensive combat readiness, or to be transporting the heavier equipment and seasoned personel to the US to be augmented with new units in preparation for re-deployment elsewhere.
Thus, as has been mentioned earlier, specific units at specific locations are NOT equivalent in terms of numbers, but ARE equivalent in terms of combat capability.
So…
a Russian INF on the German Front represents a LOT of men with small arms and limitted support and heavier elements.
a UK INF landing in Norway has light sea-born support and air support for a smaller number of men
a USA INF on Midway has defensive entrenchments, aircraft, technology and artillery with a small number of men.
And as units are moed around the board, the “invisible logistical element” comes into play, where units are augmented (or depleted) as they move through various terrain and enter various theaters of combat operations. That invisible logistacal element is where a Pacific INF get boosted in the several turns it takes to get to Europe, or where heavier elements (especially mechanized elements) are stripped from European units as the manpower moves into the Pacific.
Of course, the only real breakdown of that is in terms of Japan’s land units that enter Asia, which SHOULD deplete as they cross Siberia, but instead miraculously become European grade units (though perhaps justified by Japan forcing local peoples to join the war effort to augment the advancing forces on the march to Moscow…)
