Once again it really boils down to differing standards and inevitable problem of quality control during war. Soviet Union had it worse in general, but every participant had their share of wacky and dramatic problems with production on very mild to small scale. Especially as the war progressed and calibres increased what really mattered as far as rough theory goes was getting the first hit regardless did it actually penetrate, and having a range finder makes getting the first hit much more likely and having crews trained to use the rough range finder speaks for itself.
And even with the range finders, the first shot tended to miss, at longer ranges. The curious thing for me is, that whenever the quality of soviet optics comes up, this one report, just this one singular report is used to prove how amazing they were. What I'm not saying here is not that this investigation of soviet optics was partial or some sort of hoax, I do believe the results. The optics provided for testing most likely were the best the Soviet Union could come up with, but in no way would be in line with what the actual troops had to work with on the field.
The 'good enough' way of thinking even supports this, the tanks were not made to last years, engineered to perfection (and I use perfection here generously, because over-engineering things can and will make things more complicated and even fragile) and beyond like german tanks. Also, think about the Berlin victory parade with IS-3s trundling through the city and allied generals going to fits over how amazing and imposing machines they appeared to be. And in reality it was just a facade, a troubled machine that never really shone. I seem to remember Egyptian IS-3s getting trashed against Israeli medium tanks later along the line.
Another point of success for the germans might have also been the fact that even if all crew members were specialized in their own position, they also had training in other vital functions of the tank. Thus they would be able to stand in for an incapacitated crew member with a better chance of actually succeeding in the given task.
I do not necessarily see it as trash talk since every good equipment has their downsides. P-51 was very dangerous to take off with high fuel load since it was very unbalanced, Bf-109 was tricky mistress to control especially on higher speeds which had certain tactical limitations (though arguably they did mean it was impossible to exceed dangerous G-forces in simple move and damage\destroy the airframe), open bolt firearms ala PPSh and MP40 can be accidentally discharged by slamming the gun hard enough - or say accidentally just bumping it into something hard like a door - and whatnot. In this context since the usual consensus is that Panther is God-tier and for the sake of inciting another forum argument, Sherman is the complete piece of garbage-tier it is very easy to read any challenge to those like someone is trash talking, although logically reasonable conversation should be able to distinguish even faults or potential issues of said equipment.
Very good points. All military designs are compromises in the end anyway. It's just what the designer/person making the order is willing to sacrifice first/most. Even if I do adore the looks of the Bf-109s, the narrow landing gear proved to be a pretty tricky on landing, for an inexperienced pilot. Yet it never was "fixed", maybe it just couldn't without re-designing the damn thing entirely. And since it was a proven successful design, the sacrifice of a number of rookie pilots was easier to accept.
Even if the Panther, when maintained properly, was a pretty damn good medium tank, it certainly wasn't perfect. Nothing is. The problem with the final drive is well known and often quoted, but as it was also known back then, people just got on with it. It did not immediately relegate Panther to a piece of junk, and you'd rather face enemy armor in anything else but that. This is not a direct reply to you, but it's just on the tracks of my train of thought. The Gun was more than adequate at taking care of it's adversaries. Some of which could not return the favor frontally at normal engagement ranges for the Panther. The side and rear armor is nothing to write home about, but neither is it in many tanks. Then again, if you have enemies to your sides and rear, you're doing it wrong.
I remember someone criticizing the "notoriously brittle german steel" somewhere earlier. As far as i know, the soviets had the most brittle steel of the combatants. Causing massive spalling even on non penetrating hits with guns of high enough caliber/velocity. Anyway, even here it's a matter of compromise. The harder the steel is, less likely is the shot to penetrate, but the steel also is more brittle. And I do remember seeing many a notions of germans missing some vital ingredients for the steel making later in the war, causing the steel to become more brittle.
Some historians and/or researchers have refuted this, saying that the steel germans produced still met the specifications set for it, and that those specifications had not been changed during the course of the war. And when i say some I recall Hilary Doyle mentioning it on some show, must have been in a book too, and at least Dave Lister has said similar things. This how ever does not necessarily mean the quality has stayed the same, just that the specifications are met, but perhaps not exceeded by as much as before. I do recall seeing that germans had to replace tungsten with vanadium in their steel making process, and that supposedly would make steel more brittle. I'm no metallugist, so I just have to trust others on that.
Another thing altogether is, does the drop in steel quality mean that the tank overall has become worse? Let's assume a reality where the drop in steel quality would not need to happen due to different prevailing conditions. War is not being lost, Hitler is not screwing things up and and we have the real Panther. The original Panther. Heck, this real Panther could even be better than the original Panther, as people can't seem to decide when the armor cuality started to (supposedly) fall. And Panther was a quite late war tank.
Long ramblings short (I do apologize), the shortcomings related to the war fortunes need not be the benchmark by which the tank in this game is judged.
PS. If changes in armor quality can be modeled in HoI4, I'm all for it! More important resources!
