Fallen Angels (White Dwarf 281)

The Fallen Angels hate the Dark Angels with a fiery passion and must assault them if the are able to in the Assault Phase. Note that if Cypher joins the Fallen Angels and they are forced to assault, then he must also join the assault.

Automatically regroup when falling back even when at less than 50%. Enemy advances are treated as a new Assault (enemy striking +1A the following turn). If the enemy does not advance, the Space Marines can move, shoot, and assault as normal in their following turn.
