Say that to the T-34s that were invincible to everything except 88's when they were introduced to Jerry.
Could the Panzer IV or V(Panther) rival it
Panther wasn't developed yet. P4 needed upgunning before it could properly face T-34s.
Is that why the Marder I - III were developed ? I always thought they were supposed to be TDs
Never shown pic of a secret weapon that could have changed the war
