This thinking remained pervasive into the dawn of World War II, when most tank guns were still modifications of existing artillery pieces, and were expected to primarily be used against unarmored targets. The larger caliber, shorter range artillery mounting did not go away however. Tanks intended specifically for infantry support (the infantry tanks), expected to take out emplacements and infantry concentrations, carried large calibre weapons to fire large high-explosive shells—though these could be quite effective against other vehicles at close ranges. In some designs - for example, M3 Lee, Churchill, Char B1 - the larger bore weapons were mounted within the tank hull while a second gun for use against tanks was fitted in a turret.
