A7: Loser: Break, and withdraw from the assault
After it becomes clear which side wins the assault, formations on the losing side become Broken and must withdraw.Clarify. Other text says you don't have to make a withdrawal move — it is just that your units may be destroyed if you don't.
If a losing formation was already Broken when it was assaulted then the whole formation is destroyed; remove all its remaining units from play as casualties.
Any other formations on the losing side that were in a position to have lent support (that is, they were within 15cm of an enemy unit directly engaged in the assault) receive one Blast marker each, even if they did not actually lend support — these Blast markers represent the detrimental effect on morale of seeing friendly forces defeated in an assault.
