1. Build arty - well let's start with an old favorite, if it's a way for soviets to deal with Elefant it shouldnt be a problem for Germans to kill ISU with theirs
2. Build Elefant - well this one is obvious, no soviet vehicle can counter Elefant
3. Build halftrack and shreks - put shreks into a halftrack, go at the rear of ISU, unload and kill ISU (halftrack is not meant to survive, its just a transport and a way to block ISU retreat)
4. Use smoke bombs/barrage + some tank - use it for flanking?
5. Pak 43 - well since it still shoots trough objects, it can engage ISU with no risk, it got buffed this patch also
So many options what to choose! But if soviets need to deal with Elefant its pretty much arty and call ins, yup
Anyways did ISU became problem in 1vs1? is it really an obstacle all you bright minds cannot surpass ?
Bombing and strafing also help, it's a lot weaker than the elephant
