Not sure which version you have, but the loss parameter in DA is hardcoded. If you want to control how a unit moves as it withdraws, you can give it a route and check the "Withdrawal Route" radio button under "Retreat Parameters". However, keep in mind that, depending on the unit's level of suppression, command status, fatigue, logistics, etc, there is a chance that it won't move at all and sit there and whacked to death. I have used this function with success to set-up a delaying action, but if the enemy has you locked in its sights and brings a combination of arty, air, and direct combat, it may be a case of DIP (Die In Place) for that unit, even with the max loss at 30%.There are some retreat parameters in DA, and the Maximum Loss is 30%. Now I want to let my unit don't retreat or retreat until Max Loss is more than 30%, Does anyone tell me how to do that?
