Well, that's part of what forts are for... deterring attack./QUOTE]
the original poster is referring to the AI bug that it will place far too much weight on even a low-level fort in its calculation of whether to attack or not. e.g its hypothetically possible to survive as Poland by building even a low-level (3-4) fort in Warsaw. The German army will surround it, but never attack; even if they have massive superiority in numbers, equipment etc.
