I was curious as to why the Sturmgeschütz Abteilung was redesignated Brigade? A Brigade, as far I know, is a larger that regimental size unit. However the Sturmgeschütz Brigades seemed to be simply Abteilungen with additional Stugs. They still had three batteries, and the commanders of the brigade was still an abteilung level commander. So, why were they renamed as Brigades? Thank you very much.
