In my recent PBEM I as Entente player now am busy in pushing back towards German soil in the west in 1915.
As it can be seen in the next pic, the selected German unit has a base defense value of 22

Now I selected one of my units and check the combat prognosis display. Now the same German unit has a base defense value of 26.

22 to 26 is a remarkable difference and a heavy game changer if I dare to attack this unit, hence the bad prognosis. Any idea where this difference comes from? Are parts of the displayed values unreliable or modified or am I facing a sort of bug or feature I just don't understand?
