マチルダII歩兵戦車
In response to the difficulty of penetrating the thick armor of British infantry tanks (Matilda and Matilda II) during the Battle of France, the Germans had tested a gun — based on the 5 cm Pak 38 anti-tank gun — on a Panzer IV Ausf. D. However, with the rapid German victory in France, the original order of 80 tanks was cancelled before they entered production.
