I took a look at the DA interface and there is a way to give basic orders to each unit. The available orders are:
- hasty defense
- deliberate defense
I can't seem to find any specific references that explain in detail what each of these postures does and how it affects the unit's behavior. There are several DA tutorials
and reference manuals in the GameSquad download section and there may be an explanation in one of those.
As for setting an exact percentage before the unit will withdrawal, I don't see a way to do that, but it could be there and I'm missing it.
Curt Pangracs is one of the instructors that uses DA in the classroom and he ought to be able to answer these questions in much more detail. I'll see if I can get him to reply to this thread.
