Oddball explains that his crews have fitted pipes to their tanks to make their undergunned Shermans seem more menacingnote in reality, the tanks used for filming had been fitted with larger guns after the war. In fact, there did exist a Sherman variant (the Firefly) which had a far more powerful gun (the British 17-pounder anti-tank gun) that was quite capable of knocking out a Tigernote though not a King Tiger or a Panther, and was actually more powerful than the famous 88mm Tiger cannon or the 75mm gun used by the Panthernote not that this was a decisive advantage since the Sherman was under-armored as well by 1944 standards: the German tanks could knock out a Sherman tank at any range. The Germans did see the Firefly tanks as a serious threat, but their reaction was quite predictably to attempt to eliminate them first and leave the regular Shermans for laternote tank units needed both kinds since no good high explosive shell was available for the 17-pounder at that time, leaving it excellent against tanks but nearly useless against infantry or buildings, which was the forte of the regular Sherman tank guns. This lead the Firefly crews to do anything they could to hide their larger gun (e.g. using white paint to make it appear shorter) rather than try to emphasize it.
