loking at the low penetration from some AT units...its even more. a jp4 has headache to penetrate a ISU. Even panthers an AT guns bounce often on it....because it doesn't need to come close ...it can one shot most AT guns crews from range 70.
So use adequate unit?
Why are you ignoring top tier TD for the faction and bring up mid tier TD against a top tier unit?
Do you also complain about Easy8 sherman armor after trying to use Puma against it?
JP4 is not supposed to fight heavies.
That's why panther exists.
You are comparing inadequate unit to prove a point that doesn't exist outside of your head.
And no, panther doesn't bounce often on ISU, even if you stay at max range for whatever mad reason, majority of shots pen it.
Also, if you want to bitch about ISU, make a thread about ISU.
Stop derailing this one.
