I remember wathing something like that on youtube, top 10 fighters or something. Pretty bad program imo, just picked what the American audience wanted to see.
In quick defense, there are I think three (THREE!) different top-10 programs. One called "Top 10", one called "Greatest XX", and I do not remember the last program. I would have to go check my DVR to see which recordings I kept, but I think the "Top 10" show is good and the "Greatest XX" was not. I do not remember feeling like any show catered to the Americans though, one actually uses online polls as part of its answer, so that could be part of the problem. Sample winners: Longbow Apache (helicopters), T34 (tanks), AK-47 (rifles). I have no disagreement there. I do disagree with the Swedish turret-less tank that made one top-10 (for ingenuity and innovation), but thankfully Sweden has since switched to the German Leopard. I love the German tank naming convention, for what it's worth.
Anyway, briefly one the T-34: the revolutionary thing about it was its armor, as has been said, and then later of course just the pure number of them. The armor was amazing because it was the first mass-produced tank with sloping armor, increasing the effective thickness of the armor just by its design by I think 20%. After its success, of course the new armor design was emulated by everyone and T-34 wasn't as good, but by that time the war was already won anyway.
The other thing was the numbers. When they were mass-produced, there were just too many for the Germans to take on (especially because the Germans refused to use lower-quality parts, although the min-max curve definitely favored more tanks at slightly less quality). In fact, the German tanks were unreliable -- if this makes sense -- because they used such precision parts.
The OP has generously yielded his topic to this somewhat-absurd historical debate, but let me ask @OP: did you want a system where it shows how many men were lost from each brigade (armor/infantry/etc.)?? Or did you want better intelligence on the enemies' units after you fight them?
