Ravenwing

The [Dark Angels Space Marines] Ravenwing may go onto special Dodge orders at the start of the Movement phase. The detachment uses all of its speed and skill to make themselves a blur of movement, making it extremely difficult for the enemy to accurately target them. Indicate this by placing the Order dice with the '!' face up next to the detachment.

If the Ravenwing is on Dodge orders the detachment may move normally in the Movement phase. All units in the detachment may add +1 to their Armour value (up to a maximum of 6+) but must then halve their Firepower (rounding up).
