This is how the Campaign is structured. I am still learning how it all works but from what I have gathered the first part defines the names of each region and the second part denotes what maps are contestable in each region.
So if you win a map you get to choose a region to attack that is next to where you currently occupy and then you choose a map within that region if there is more than one.
Below is the maps I have (second part) at the moment but it was a random grab of maps. If someone wants to put some thought into a better list, i am happy to try some different combinations
First Part
TerritoryNames[0]=Steppe
TerritoryNames[1]=Mechetka

TerritoryNames[3]=Mamaev

TerritoryNames[7]=Ouest" ( west )
TerritoryNames[8]=Centre" ( central )
TerritoryNames[9]=Sud" ( south )
