When you stand close to these guns you realize why tanks can have such a huge demoralizing effect on its enemies, blast noise are enormous. And I certainly don't blame the Allied crews who felt the urge to run whenever a Tiger showed up.
The 8.8cm gun on the Tiger Ausf.E is much more powerful than the 7.6cm gun in the above video, and a HE shell from it has the same effect as that fired by the 90mm T8 in the first video. One shot can easily bring half of a normal two story house down.
