I've had trouble keeping units in supply ever since I bought the game. I try to keep my units within 4 hexes of an HQ. I try to keep the HQ within 4 hexes of a city. Why then does this some times not work? Ex - I have Balboa in Africa four hexes (including the one he occupies) from Tobruk but my Italian Army attacking Alexandria has a supply rating of 4 even though Balboa's and his accompaning airfleets all have an 8 rating. I read the rules way back when I originally got the game but the rules for supply didn't seem work as described.
Would someone please explain how supply works and also decipher this:
HQ SUPPLY CALCULATIONS
supply = 0 -> HQ supply = 5
supply <= 5 -> HQ Supply = 8
supply > 5 -> HQ supply = 10
Note: Friendly HQ's can now be linked to supply each other over extended distances
