I think they represent the artificial harbor the Allies built at Normandy.
We have messed around with House Rules using them to beef up the logistics requirements of WiF by limiting a minor port to supplying only one HQ at a time unless you use a NSU in a way like the Mulberries (along with some port damage/repair rules). So there is some point to the 1944 campaign in France that historically needed Antwerp to continue across the Rhine, unlike WiF where even one HQ on one coastal hex can supply multiple Army Groups and railroads are always in perfect repair and full of rolling stock as soon as you need them. But when playing you can't remember how a few new supply rules work and it is more fun to just leave logistics invisible.
I think the NSU's represent the amazing Fleet Train (fast oilers, ammunition ships, hospital ships, the list goes on) the USN developed. When the Royal Navy wanted to deploy in the Pacific in 44-45 it was hard for them to work with the USN which had a far more advanced naval logistics system by that time.
On China, someone mentioned how to interface the ChiComms and the Nationalists. From what I remember of creating a paper map of the cWiF map, there was never a solid front line across China, but rather several mini-fronts that weren't connected, only one of which might have Nationalists & Communists in adjacent hexes, so I think that won't be as tricky of a waltz as it is now on the smaller scale maps.
