I read https://jalopnik.com/ten-obvious-eng...nto-1700377652, which contained:

“Porsche was so confident he would win the contract for the Tiger tank that he began producing chassis before the contract was awarded. When his design was judged inferior to the Henschel he convinced the military to let him build tank destroyers out of the chassis he had already began producing. So it began life as a loser.

Then they built it, but forgot to add opening for machine guns, or openings for vision to the side or the rear.

[...]

Not willing to call it a day and melt the things down as scrap the tanks were “retrofitted” by providing the crew with a machine gun with bent barrel so that they could fire at nearby troops through an open hatch. This of course meant they had to open the hatch in the middle of the battle, which kind of defeats the purpose of an enclosed armored vehicle.
