Question:
If units start a turn loaded on transports in port, are they in supply? This is significant, because if the answer is yes, then Allied troops can start the game loaded in transports for a turn 1 invasion of southern France (the extra 30 NMPs are needed.)
Answer:
Units embarked upon ships trace supply by the normal rules, so if they are in a port hex and the NT/LC is in port (not at sea in the hex) then, yes, they are in supply. Note also that for your first turn invasion, the units and NT/LCs they are embarked upon could be set up in the North Africa Holding box at start, they needn’t be deployed at separate ports on the map. Also note that since they are already embarked, port capacity is not an issue; all of your NT/LCs, along with anyone they are transporting, could be placed, for example, at Bougie during the initial phase and carry out their invasion from there. The fact that Bougie is only a minor port is immaterial. Note also that any units embarked upon NT/LC could remain in the North Africa Holding Box, or any on-map port, and remain in supply from turn to turn, indefinitely.
