”ARMOURED VEHICLES PART 10, Assault Guns” (på engelska). jaegerplatoon.net. https://www.jaegerplatoon.net/ASSAULT_GUNS.htm. Läst 13 september 2022. ”As often with armored vehicles, there was a variety of official and less official names & abbreviations for this assault gun version. Early on when assault gun was introduced to German use their military simply called it sturmgeschütz (assault gun), since there were no other designs to mix up with. But especially once PzKw IV medium tank based Sturmgeschütz IV was introduced, there was obvious need to separate the two - hence PzKw III tank based assault guns got named as Sturmgeschütz III or Sturmgeschütz 40.”
