An Army Group during Movement:
1. Combat Movement:
An Army Group that contains only units that can move 2 spaces - such as Mechanized Infantry units, Tank units, Waffen-SS units, Soviet Guard Infantry units etc. can move 2 spaces during the Combat Movement phase.
Note:
Even if there is only 1 unit inside the Army Group that can move 1 space - such as an Infantry unit - the Army Group cannot move 2 spaces.
2. Blitz Movement:
Even though a Blitz Movement is quite rare for an Army Group this movement is only possible when the Army Group contains the following units:
- 2 Tank Armies (or Panzer Armies)
- 10 Tank or Panzer units
A Blitz Move is also possible if the Army Group contains the following units:
- 2 Tank Armies (or Panzer Armies)
- 10 units that are paired in order to Blitz (Tank + Mechanized Infantry etc.)
3. Non-Combat Movement:
The same game mechanisms that works during Combat Movement also applies during Non-Combat Movement.
However, it is possible to split up an Army Group during Non-Combat Movement - and transfer any Armies and units from the Army Group to another territory - and then move fresh reinforcements into that territory - and combine all these Armies and units into a newly formed Army Group.
This newly formed Army Group is ready to defend in the same round - and ready to attack as an Army Group in the following round.
