with 1.10, we will now have two different kinds of "capture" - and two different meanings for the word "zone".
we have good old field capture, same as always. and the way to win the reset is still to capture all an enemy's fields but one.
but now we will also have zone capture - capturing a zone's primary field, which gives you control over the zone's supply systems, but does not mean instantly taking control of all the fields in the zone (note that you can't zone-capture an enemy's "primary zone" - the one that contains the HQ).
so in this supply-system sense, the word zone doesn't mean the fields in a particular area, it really just means the supply system in that area.
but of course zone also means the actual geographic area covered by a supply system... and so we will have situations where a country owns "half a zone" in the geographic sense, but does not own the zone at all in the supply sense.
be warned.
