understanding Command and Supply

[Steelwhip]

ahhh okies...thats the part I was missing..that the explicit supplies override the normal supply rules and I need to get supply trucks to those units then. Ok..that I can do...I just couldnt figure out why they were not getting refueled through the HQs....and that under Explicit they dont refuel from the HQs......totally didnt even think about that.

which now brings up a seperate issue....
supply depots have a range of 10 (at least in the campaign im playing right now) I also have...2 or 3 units of supply trucks. The range of 10 for the depots doesn't seem that much to sustain a campaign advance across the Sinai of about 100 hexes....how am I supposed to sustain advances across such long distances?
