This is a weird one but i introduce the T121 powered commanders cupola
It allowed the mounting of twin m2 .50 cals or twin m1919a4 .30 cals in place of the standard commanders cupola
Dual 50’s plus the hull and turret .30 cals sounds like cancer as your sqaud gets plowed by a HE round and then the stragglers get to catch a planes worth of 1 second machine gun burst mass.
Pershing is far more armored than the standard allied Sherman, Sherman is just point and click once you get a long 88 but the pershing has a better chance and you actually need to aim unless you have the pak 43 88 then back to point and click.
