Axis have several legit supply sources, but all troops not adjacent to cities/resources still have supply 1 instead of 3 you normally get from city. That rule makes sense for African deserts, but strange for European territory with good infrastructure, like England.
Same is true for Sicily by the way supply is 3 near cities and 1 far from them for both sides, no matter who controls Rome.
So question - is that intended effect or bug of some sort?
