I think the 25/100 is being mis-used in context elsewhere in the rulebook.ORIGINAL: Champagne
Thanks for your input.
You are probably right!
I had not noticed 20.4.3.1 in this light before. My confusion is due to the fact that the manual states on more than one occasion that 25 hexes and 100 MP amounts to full supply for the Corps HQ tracing to the Railhead. This is not accurate.
When you are over the 25/100, you are Isolated, and thus, unable to be supplied even if a wide-open path of hexes is between you and railhead.
Again, this is my interpretation of rules.
