Jackson had up to 108mm of angled armor.
Panther had up to 110mm of angled armor.
Tiger had 120mm.
P4 had up to 80mm.
From a realism standpoint, Jackson has no armor at all in CoH2.
But game isn't balanced around realism, you have failed MoW series for that.
Jackson also has an open top turret. Realistically indirect fire and fighter MGs should kill it.
Agreed that it’s not realistic.
