Moving along a bit now to examining the dynamics of Panzer Division organisation change yields the table below.
Over time the division lost tanks but gained infantry. Also, some internal command changes occurred highlighted in green (Brigade HQ components dropped after 1939) and yellow (Motor Cycle Bn moved) and orange ( Flak Bn added).
More units were armoured as equipment became available and finally the Artillery was strengthened - 1st Panzer Division used as model.
Next move is to draw organogram and develop data tables.
