Until the T-34 came along Russian tanks were nothing more then target practice for German tank commanders. However tanks such as the might Panzer Tiger were not invincible, attacks from behind (i.e. shooting at the tigers only week point), ambushes could all be used to disable a tank. After that you have anti tank artillery fire and air attacks. But in all honesty if you look at how the start of the German offensive against Russia went down all of these tactics didnt really make that much difference. One of the most unusual methods I have heard of is they trained dogs to attack German tanks. The dogs would have explosives fitted to them who were then sent out on a suicide mission. I heard this was abandoned because the dogs kept attacking Russian tanks because Russians didnt have any captured German tanks to train the dogs.



The turning point in tank warfare was when the T-34 was introduced, its front gun was powerful enough to defeat any German tank head on (although I dont know if they ever fought the King Tiger), it slopping armour made it difficult for German gunners to get a good hit and they were fast and easy to build.
