Val I can go over settings and keys with you sometime in game. As for the not having distance to the target like in planes there isn't a way to get it. I believe this is a good thing because it makes people estimate distance to the target. If you were to give someone exact distance in game they would be able to go to a test drive before and figure out which elevation mark to use for each distance. This would essentially turn RB into AB minus the penetration indicator which once you start to recognize weak spots you won't even need. And covering your last point of aiming and targeting I will be honest with you. I shoot completely with feel, I know there are ways to use the crosshairs to get a better estimate for distance but when you are engaging a tank and they are shooting back I won't be sitting there taking the time to try and guess range. The easiest way to get comfortable with the gun on your tank is doing a test drive, 5-10 minutes on the range will give you a chance to shoot at targets and get a feel for round drop in that tank.
