Supply for besieged units

[TheDoctorKing]

This is a general question I have about the AGE system as a whole: if a unit is besieged, but his side has military control of an adjacent area, can he draw supply through that area? Under what circumstances?

How about if the unit is in a port and the attacking player does not have control of the adjacent sea/river area?

You can have supply pass through a region if you have 25% + MC. So if you are besieged, chances are that your MC is under that, unless the siege just started and the besieger don't have a firm control around your location. So the answer would be: NO, you can pull supply from an adjacent region (you can't even take it from the countryside).

If you have an unblockaded harbor, things are much better otoh.

So my army besieged in Fortified Lines Kiev was getting supply via river?

In RUS, I'm noticing that there is no special river transport pool. How does supply move by river? Does it use the rail pool?

[Pocus]

Is it a true river (i.e a region) or a cosmetic one? Only the former can have supply pass through.
I'm not sure, as I did not participate in RUS except for some advices, but if this follow the ROP model, then there is an unlimited river transport pool in RUS, but only for supply, so I bet that if the river is not interdicted, supply can pass through.

Yes, Kiev is on the Dnepr, which is a "real" river that ship units can enter. So in my game, no doubt the supplies were moving down the river from the nearest upriver port that I controlled (Chernigov? name escaping me). And my supply totals were declining when the Whites had cut the rail line between that city and Kursk and the rest of the Red world.

Good to know. A major advantage for the Reds since they control the navy.
