Are these bugs or is it me?
It's you.
The Steam version have received quite a few updates since april 2015, last patch came out in september, so many of the described issues may have been fixed already.
I'm not a developer by the way.
1. I've just tested this both with the T-62 and M60. Whenever I order the driver to halt there is no turning to any side, tank just halts.
2-3. Did not notice any problem with that either.
3-1. You overestimate the effects of an HE tank round. For example,
This is
Figure 2 – 25-pdr HE ground-burst, angle of descent 20º - Percentage Casualties to men standing in the open around the point of burst of the shell. As you can see, there is no guarantee that even a standing man within 10 meters of impact point will become a casualty. Yes, i know that M60 does not fire 25pdr HE, but the fragmentation pattern will look similar, not like a circular AOE splash as seen in many other games. A prone soldier in realistic terrain will not get hit every time just because a shell exploded anywhere within 10 meters of him. Not sure about the blast effect, but would not expect much in the open.
4. Have noticed quite the opposite - the platoon members often are more effective than I am.
5-1. And?
5-2. As they should be. Not every hit on the fuel tanks or ammo will lead to an immediate destruction. If you hit the propellant it will burn and this may lead to an explosion after a while, that's what you are describing.
5-3. Bounces as in ricochets? What was the angle of impact? It is usually displayed in the statistics.
6. 90 degrees at 40 kmph?
Also here at around 22:45 an Abrams loses a sprocket in the mud, without "getting slightly over excited while driving".
Tracks should be fragile, much more fragile than in other games. Especially if you are making sharp turns in the difficult terrain while going 40kmph.
7. Haven't noticed anything strange here either. You can hide behind smoke and vegetation, and you should change your position often.
Also, please make some screenshots or videos of the things you've described.
