Another example:
The German Army Group North occupy Novgorod. Army Group North consists of 1st Panzer Army and 3rd Waffen-SS Army - plus 10 Panzer units.
During a German attack, the German player decides to split Army Group North:
1st Panzer Army - plus 5 Panzer units - attack Soviet controlled Belarus.
3rd Waffen-SS Army - plus 5 Panzer units - attack Soviet controlled Archangel.
1st Panzer Army and 3rd Waffen-SS Army both get their Army Bonus Dice Rolls, since these two Armies no longer share the same territory.
