[DRG]

The basic Panzer Gruppe ( Formation 13 ) draws all the tank choices from all medium tanks available from whatever date you have set for the game or editor. What you see in the OOB itself are the Template units that formation uses and in the case of Panzer Gruppe that is the PzKw IIIE 3.7cm but that Template unit is just a placeholder for all Medium tanks available in the time period you are viewing.

Ultimately though the entire span of time the Panzer Gruppe exists ( 6/39 - 12/46 ) these are all of the Medium tanks types that will become available when the Gruppe is selected between their in and out of service dates.
