You're not hearing what I'm saying.
Also, when the hell did dozens (as in multiple dozens of Tiger II's) bump into a large group of IS-2's? I can't find a documented encounter at anything greater than company-level.
You really did not read anything I said, go back and read up. Tiger II's did not stand toe to toe with IS-2's, one direct hit from a IS-2 was enough to
DISABLE a Tiger II. True the 88mm can penetrate a IS-2, however one round was enough from an IS-2 to DISABLE a Tiger II. Why? Poor welding and craftmanship. You dont' seem to realize the armor was NOT the quality steel it should of had, instead they used a low grade steel. So in this case the armor is not as strong as you want to believe, however I have plenty of source to prove this, you have NO proof what so ever, only by what the stats of the tank are in perfect condition. Except in wartime there is a shortage of everything at this point: HIGH grade steel, Gasoline hell even ball bearings were in short supply.
I proved the Steel grade quality was POOR - this leads to poor armor protection - add POOR welding on top of that means an easy kill for an IS-2 simply by disabling the Tiger with one hit, doesn't matter if the 88mm can hit and kill an IS-2 it only needed one shot and POOF goes tiger II.
You keep arguing over and over and not understanding the Tiger II did NOT stand up to IS-2 due to the defects, only thing going for the Tiger II at this point was its 88 L/71 other then that it only took one hit at times to disable it completely.
You think it would cause a "Small fracture" which is not the case, POOR steel leads to poor armor protection. It makes perfect sense that an IS-2 disables a Tiger at 2000meters simply with this lack of armor defect, which was a common problem.
Secondly you keep thinking Tiger II's were only driven by Aces - actually I can show plenty of source saying this isnt the case. Late in the war, Veterans are dying left and right - Here's an example:
"The Tiger II's 8.8cm gun could be deadly with a well-led and well-trained crew. However, LT. Col. Bill Hamberg (Army) commander of a tank battalion from the 5th armored division during WW2 remembers "As the war was nearing December 1944, I noticed that the accuracy of a German Tiger firing steadily decreased. On a number of occasions when my tanks presented easy targets to Tiger tanks, they were unable to hit our vehicles. It was obvious to me the Germans no longer had the time to train their tank crews in basic fundamentals of tank gunnery."
"As the war progressed, Germany was forced to reduce or no longer use certain critical alloy materials in the production of armor plate, such as nickel, tungsten, molybdenum, and manganese; this did result in lower impact resistance levels compared to earlier armor.[51] Manganese from mines in the Ukraine ceased when the German Army lost control of this territory in February 1944. Allied bombers struck the Knabe mine in Norway and stopped a key source of molybdenum; other supplies from Finland and Japan were also cut off. The loss of molybdenum, and its replacement with other substitutes to maintain hardness, as well as a general loss of quality control resulted in an increased brittleness in German armor plate, which developed a tendency to fracture when struck with a shell. Testing by U.S. Army officers in August 1944 in Isigny, France showed catastrophic cracking of the armor plate on two out of three Panthers examined.[52][53]
Basicaly, (and assuming I correctly remember basic metalurgy from my degreee!) Steel is iron mixed with a small ammount of carbon to make it harder. Different alloys of steel are created with different proportions of carbon and the addition of other small quantities of fancy materials -for example Chromium, Tungsten, Molybdenum... Here's a quick explanation based on the steels used in bicycles. If you don't have access to these materials, some of which were quite exotic at the time, you can't make steel as strong without choosing different materials -which might lead to altogether different properties, e.g. higher weight, more fragmentation, harder to weld/manufacture..."
Read the book Tiger Tanks by Michael Green, tells you everything you need to know about Tiger I and II.
it gives countless details on the armor when it was good/bad.
