I am trying to reflect the Polish armies low morale and cohesion at the beginning of the Russo-Polish War of 1920. I want the Polish Army to have a lower than normal maximum cohesion for various models at the start of the game. Then at various times, introduce an event which would increase the maximum cohesion of models to reflect the increasing cohesion and morale of the Polish army as the Reds approach Warsaw.
Unfortuately, looking at the script commands in the wiki, I have only found commands which adjust current cohesion rather than max cohesion for models.
So have I missed a script command that changes the maximum cohesion of models? If not, is there another approach to simulating the same effect of reduced maximum cohesion? I definitely do not want to make a bunch of duplicate models with different maximum cohesion levels.
Hopefully someone can help me out. This is a vital event for simulating changes in the performance of the Polish Army.
