And by the way: before you reject adding Independent battalions into Templates of standard formations, where would all those high profile Units and equipment go, like Tigers, jagdpanthers, Jagdtigers, Ferdinands, 88/128mm AT guns, Flak battalions, Panzerwerfer, Nebelwerfer, StuG-Abtl?
Because these were usually not organic components of divisions, but attached to them temporarily.
If you dismiss that Idea, your "historical" Wehrmacht would not field Tigers or Jagdpanthers, which would mean dismissing more than 2000 of the war's most renowned tanks.
And to get back to GD: you said in the beginning that GD would be the only formation approaching 40w.
Now, LSSAH has been grudgingly acknowledged.
Can you guess that 2nd SS, HG, 12th SS, 3rd SS, Panzer Lehr, were similarly equipped and hence, 40w wasn't the norm but is by no means a fantasy size?
