Flying models follow the rules for Skirmishers. However, they cannot use Feigned Flight, and if they have a Unit Strength above 2 and/or a close combat armour save better than 4+, they cannot use Vanguard.
Moving Flyers
Flight is represented by a swoop equal to the number in the brackets instead of using the model's normal M value. Note that any equipment or rules that affect the model's regular M will also affect its Fly move, unless specified. The flyer starts off on the ground, takes off, flies to where it wishes to go, and then lands. Flyers, therefore, begin and end their movement on the ground.
Units made up entirely of models that can fly can move or charge normally on the ground, using their M value, or instead choose to fly. A unit that flies can move over other units and terrain as it does so, treating the entire move as taking place over open ground. It may not finish the move on top of another unit or in impassable terrain. Models that Fly can make a flying charge over intervening units and terrain as long as they can draw Line of Sight to their target as normal. A unit that makes a flying charge does so using its Fly move as its M characteristic, using Swiftstride.
Flying March
A unit that is flying can march as normal, doubling its
flying move.
Flee and Pursue
Flyers always move on the ground when attempting to
flee or pursue.
