Re: Wheeded and fracked vehicle question
Look to see the color of the print for its movement AP cost number. If it is green, it is classified as a "wheeled" vehicle; if blue, it is "tracked." You then apply the bonuses and the terrain that is not allowed as noted in the appropriate movement column on the terrain chart. Note that the bonus symbols for wheeled and tracked are also color-coded green and blue respectively.
As you note, one German vehicle (Scout car, I think?) has both a green "wheel" bonus and a blue "track" bonus. The movement AP cost number is in green, so the vehicle uses the "wheeled" terrain column.
