supply question

[Mr Grumpy]

But, more importantly, AFAICR only roads affect VST supply level because it is supposed to represent supply trucks, not trains (VST = Virtual Supply Trucks). Unless I am mistaken, rails are not factored into the equation.

Yes Ed is correct, from the rules....."The rule computes a path of minimum movement cost for a motorized unit in Travel Mode between the Supply Sources and the location of friendly forces on the map."

So rail lines are irrelevant as far as VST supply is concerned. ;)
