Description: When performing a Pivot:
1 - Mark the Centre of the unit.
2 - Remove the unit from the Battlefield, and then place it back on the Battlefield facing any direction with its Centre in the same place as before (following the Unit Spacing rule).
When performing a Wheel, rotate the unit forwards up to 90, around either of its front corners. The distance moved by the unit is equal to the distance the outer front corner of the outermost model in the first rank has moved from its starting to its ending position (not the actual distance it moved along the arc of a circle), see figure figure/wheels. All models in the unit are considered to have moved this distance.
