6.7 - Fleeing

If a unit would perform a move or otherwise would move off of the Battlefield board edge as a result of a Movement Action, the unit has fled and is slain. A unit with the Aircraft type that flees off the Battlefield board edge is not slain and instead enters Ongoing Reserves (see 3.5) and may return to the battlefield automatically during the next battle round via Outflank or Deep Strike per its special rules.
