1.Panzer speed is faster than IS-2 turret rotation so yes,two well microed Panzer's can take down an IS-2,even better when P4 has vet1 NOS...
The stats you are basing this off of are incomplete - just because the speed is faster than the turret rotation speed doesn't mean that an IS 2 will not be able to target it - this would essentially only work in a vacuum where the IS-2 is not using terrain and both the pIVs managed to teleport right next to it.
