There is a reason why 9/10 games on 2v2 calliope and Landmattress are used. Simply because of the often wipes of axis infantry. Unit preservation is never rewarded but often punished due to the units I mentioned above.
Besides Brummbar, and strum tiger, generally speaking, there aren't much other axis tanks that just completely squad wipe off 1 shot as much as the Allied counterpart. It's bullshit and cheesy. That's why I see the same shit in every game
Walking Stuka and Pwerf are just as common and good at wiping squads as the LM and Calli each have their ups and downs, as for the other comment, well:
King Tiger
Vet 1 Jag
Tiger
Brummbar
Sturm Tiger
AVRE
Bulldozer
KV 2
ISU
Pershing
All capable of one shotting squads with relative ease whereas the Cromwell, P4, Sherman etc can all one shot too if the models bunch up badly...
