'Wheeling' is the best way of making an alteration to the direction a unit is facing whilst still being able to advance. To wheel, the leading edge of the unit moves forward, pivoting round one of its front corners, as shown in Fig 124.1.

When a unit wheels, every model counts as having moved as far as the outside model. Once the wheel is complete, you may use any movement the unit has remaining. Unless it is charging, a unit can wheel more than once during its move and can alternate between moving forward and wheeling.
