Hello,
I suggest to rework all of the Tank sound and maybe the ones of wheeled vehicles so it is much more immersive and realistic. Right now Tanks sound rather like cars and the engines cant be really heard loudly. Track noises are very loud and annoying. I also suggest implementing a slider for volume of vehicle for the player (doesnt change other vehicles). What i also noticed that the sound comes directly from the center of mass or just in the middle of the tank. (dont know at wheeled vehicles)
Also they should have unsmooth sounds so if a tank starts, they will do a couple revs until they run a bit smoother like in this video:

And the legendary Tiger II engine (for all panthers and other HL230 Tanks)

We should also have the sounds for modders.
