@@yourcasualfinn2213 according to Technical Memorandum ORO-T-117 "SURVEY OF ALLIED TANK CASUALTIES" , gunfire "...exacted the highest over-all percentage (54%) of tank casualties in all theaters." This would be around 1/2, (50%), the value you gave (4/5) would equal to 80%. First off, you are wrong on a numerical basis. Second, it depends on whether you define disabled as destroyed or separate. Out of 449 vehicles destroyed, 51% were due to enemy fire, so you are not wrong on that. However, out of 588 disabled vehicles, 52% was due to artillery & mortar, with direct fire being 28%. These are all sampled from battle casualties of the 6th Armored Division from the period of July 18, 1945 --> May 8, 1945. However, more vehicles were disabled than destroyed, then affirming the fact that you're wrong on a numerical basis. This is pretty consistent across most of the charts, with disabled and repairable vehicles being higher than destroyed vehicles.
translatioin= "Most of the Nazi tanks destroyed were destroyed by American tanks. However, the Nazis left several times more tanks than the destroyed ones on the road and escaped barefoot. Most of the damage to US tanks was caused by anti-aircraft guns, mines, rockets, and various engineering obstacles."
Fun Fact: In WWII M4 Shermans encountered Panzerkampfwagen VI "Tigers" a total of 3 times and won a total of 3 times; two of which were from the Tiger being shot up, and the third of it breaking down mid-combat!
Tiger 201 blew up the Pershing fittingly nicknamed "Fireball" before reversing on a wall and getting stuck. Stone wall confirmed more lethal against a Tiger than a Pershing.
The flaws of the Tiger II included: Stupidly heavy. Overengineered. Easily flanked. A transmission that broke down constantly. Poorly welded armor sometimes. Is it really the best tank? The Sherman was so effective that i don't know any of its flaws, other than the earlier models had a transmission worse than the HVSS transmission.
