with the distances in game, we shoud not have any richochets at all.
Even the Panzer IV, shoud be able to penetrate the IS2 on Arad from near evry direction, with at least the second or third hitting shoot.
Most tank fights in the eastfront took place on ranges beyond 1000m and thats where richochets REALY come in to play, cause the velocitcy from a long 75mm gun or 88 is high enough to penetrate the armor from any soviet tank any range below 1000m.
red orchestra armor model, isnt working right, not even near realistic. You can go to Orel, that has some REALY realistic ranges there, at least the most realistic so far we have in game, take a T34/76 and get in fight with some tiger or panther there, count how much richochets you have from your T34 armor, and check what distance it is (bigest you can see on that map is, if i believe 1000m), this was typical distance for germans to destroy soviet armor, at least early/mid war soviet armor without any heavy richochets at all. Panthers had the most accurate optics and a formidable gun with great ability in armor penetration. Practically, from evry archived shot a panther fired, near evry time, the second one was a hit (of course, not always penetrating).
The tanks in game ... are fun, but often frustrating and a "who clicks first and/or faster" game. I know Ro Dev Ram, stated that the tank-health is NOT hit point based, but in 90% of the time it feels that way. When you get in fights with a tiger and IS2, and the Tiger is a bit angled, its near always about, who shoots first and realoads his second shoot faster ...
