The maps in Armored Brigade represent real world regions, and are made of 30x30m squares. These maps include the North germal plains, the Fulda Gap, the Ardennes, the NTC, the Italian-Yugoslav battleground, a Finish-Russian war arena, and two or three more. Plus CCIP's detailed Grozny and Chechnya map mods. For every scenario, the battlegorund gets choosen form one of these very huge regional maps, and it cna vary in size, from small to quite big sectors, like the size of battles also can vary from company level to brigade(s) level.
