I haven't played CM, but as a longtime Steel Panthers player (well, long time in the sense that I played the original version and play World at War here and there, but not longtime in the sense that I'm really GOOD or anything
), I can tell you CM isn't exactly turn based. Traditional turn-based games are "I go, you go". CM is "we pause the game, issue orders, then WE go". A true turn-based game can be "gamed" in terms of things like reloading. You can still sort of do this in CM, but it's a lot harder to get a "perfect" result if you're using a "We go" system where you don't incrementally select a unit and have it fire.
Now back on point. Here's a quick SAT question:
Combat Missions is to Red Orchestra as:
(a) apples are to apples
(b) apples are to oranges
(c) apples are to pie
(d) apples are to 1968 Dodge Chargers
If you said (d) you're right. Go read OfficerMeatbeef's post for a better explanation. CM does nothing that RO does except in VERY broad terms. The two games function in drastically different ways.
As for the tank damage system, it's got its quirks, no question. We desperately need specific damage locations for buttoned and unbuttoned commanders and drivers. Track damage seems to be modelled strangely, currently, which may be a result of invisible portions of the model extending too far (like what can happen with unbuttoned commanders -- at least that's my theory).
And point-blank or short range combat seems improperly modelled currently (IE: two tanks can be at point blank range and can fire shots that ricochet off each other).
Some of this may be due to abstract data being fed into the program resulting in odd occurrences like the point-blank ricochet. Some of it may also be due to things you don't consider in the moment like VERTICAL angling. Yes, this happens too.
Case in point. On Orel76v88, I was driving a T-34. I was on a hill angled so that a Tiger was at my 11:00. I was also slightly raised so that the vertical slope of my already sloped armor was even more close to horizontal. The Tiger fired multiple shots at me, repeatedly ricocheting off me. He was probably smashing his keyboard in frustration because no less than 5 shots bounced clean off and did no damage. What he didn't understand probably was the fact that not only was I angled horizontally, but also vertically, and with my tracks hidden. Stuff like that can happen sometimes, so don't immediatly condemn the system as "OMG!! BROKEN!!"
That's not to say that there are improvements needed, but the TW guys get that and will do their best to improve things. The pre-patched version of tank combat was much much worse and they fixed it. The infantry combat is doing extremely well, so hopefully it doesn't need that many fixes. That's all good news because it suggests that they'll develop tank combat further.
