That they could catch fire when going up a hill

The weight was just too great

Especially on the Elefant since the Elefant is litteraly only a Ferdinand with extra armor and a machine gun

The big TDs, or generally any big German tankses did bad in the end of the war

The biggest problems were allied fighter-bombers

And their logistical problems

still think the TDs were a waste of time but that probably reflects modern thinking

well, probably from 1950s onwards thinking

The Hetzer was not a waste of time.

since TDs disappeared pretty qucikly after WW2

The Hetzer was very cost-effective

TDs dissapeared because of hand held AT weaponry and there not being so many tanks to shoot at.

introduction of capable anti tank missiles probably

That as well.

But if another big conflict came into play

And a lot of tanks would be used

not so many tanks to shoot at?! errrrrrrrr davy crocket a-10 milan law viper and apache

The TDs would be right around the corner, being built by every great power

dobut it

Do you now?

Tell me a conventional way to take out an enemy tank 10 KMs away.

I'll simulate it.

F-35

😃

Shot down by enemy ground to air missile.

Continue.

TD, dstroyed by some git with an air rifle

continue

nope, that wont work, fell into a manhole cover

so, back to reality

F-35 😃

where fook is my wallet

10 KMs away from a tank, and you don't think there will be multiple ground to air missiles and enemy jets on you?

s'what the Typhoon and various long range air to ground munitions are for

We're talking modern war against a great power

oh, wait... no typhoons for the US
