Note 1:
All units are hand painted in order to distinguish the various units from each other.

Note 2:
Most of the Expansion units - such as Paratrooper units - are all painted in the maximum number of units that are available to the German player.
In other words:
During the game the Expansion units are used as original game pieces - not with gray or red plastic chips under a unit.
So when Germany has 2 Paratrooper units in a territory then 2 Paratrooper units are placed in that territory - not 1 Paratrooper with a grey plastic chip underneath.
