jackson + pershing would be an unbeatable combo.
Is Jackson and IS2 an unbeatable combo in team game? Because that's more powerful than Jackson + Pershing would be. This combo is seen in basically every joint US/Soviet team game. Somehow, Axis still have a major advantage despite this "unbeatable" combination of highly armored, extremely powerful heavy tank backed up by long range, powerful TD. In a solo context, the US player can't build swarms of mediums then also get some kind of free superheavy beast (only Elite Troops gets to do that
), it's an either/or proposition. If there has been enough fuel going around for the US to build T4, a Jackson, and call-in a Pershing (200+ fuel alone), the Axis has no excuse for not being able to field an effective fighting force of its own, and the USF player has, up to this point, sacrificed its combat effectiveness substantially by not opting to gets its most effective mid-late unit (i.e. the Sherman). And since they've picked this doctrine, it means no 1919s, no Airborne, no P47 strike, no Flamer riflemen, no Easy 8s.
And this is all assuming that the Pershing is beastly at killing infantry / team weapons, because if it's not (i.e. if the 90mm gun performs similarly to the M36 90mm), then Shreks and Paks will be fantastic counters to this combination, given that the Pershing has thinner armor than an IS2 or Tiger.
It's really weird to see people say that the Pershing+Jackson combo would be unbeatable, like you've imagined that it would be unbeatable in your head then complained instead of considering ways in which it could actually be a balanced unit.
