Disorder and Cohesion Stacking Effects?

[Schweetness101]

I'm sure this has been answered before, and it's probably somewhere in the manual, but searching the manual for it is hard because the terms "cohesion" and "disorder" come up all over the place, including on the sidebar, so it's hard to ctrl-f for them lol, so I thought I would just ask.

Do the effects of cohesion levels (steady, disrupted, fragmented) stack with those from terrain debuffs (moderately and severely disordered, etc...)?

As in, would a disrupted heavy infantry unit standing in moderately disordering rough terrain have some kind of doubled up combat disadvantage, or is it just whichever is worse?

The simple answer is no. Just pick whichever is worse. Disrupted is worse than moderately disordered.
