I think the immersion of the Game regarding tank combat could be really improved by just adding a couple sounds, like flashier more loud ricochet sounds from shells that Bounce off the hull and maybe a small camera shake from inside the tank without moving your crosshair.
My argument is that tank combat could be more engaging this way other than shotting at each other until one blows with a bit more personality from the crew of your vehícle.
Example:
Now i know that fury is not an accuarate movie but this scene does show the type of sound im trying to push.
