It's the start of Turn 7, and my lead panzer elements have been slowly losing their ability to refuel and resupply. Here's the basic situation geographically:

I know supply is limited by fatigue to some extent, by distance from rail head, and distance to HQ (the HQ is very close, obviously).
Why is THIS unit so much worse off, and generally speaking, how can I improve supply delivery out there to that Northeastern edge of the advance?
I'm editing this and adding some more supply details from the units in question. Bear with me.
