The above screenshot shows the new map control overlay. The blue areas are friendly. The orange areas are enemy. Note I have drawn some blue arrows to indicate where the earlier friendly force advanced to secure St Vith in the north. The force left a wake of friendly controlled areas. It never penetrated into the woods, so these are still deemed enemy controlled. Note also the enemy pocket east of the main road. With this feature you can now get a better idea of what area you control. However, it's based on your intel. So it may not be ground truth.
