In WitW the system is more integrated. There are eight areas that require garrisons. The garrison levels required in these areas vary over time and reduce in some areas following an invasion of northern europe. In addition a number of cities also require garrisons requiring not only a security unit but also a combat unit with significant strength to be in the hex.
Failing to meet garrison requirements impacts in two ways. Firstly there is a corresponding increase in partisan activity. Although there are no partisan counters there is an impact on the rail lines and factories in the garrison area. Secondly partisan activity costs victory points.
To help the player keep track of garrisons, like in WitE, garrison cities can be colour shaded. Also you can toggle garrison CV values for unit counters and there is a Garrison Status screen (see screenshot). Finally at the end of the turn if you have missed the requirements to a level that will cost you points then a pop up will ask whether you wish to continue.
