Lead from the back

The Look Out, Sir! rule applies to an attack
made with a melee weapon as well as an attack
made with a missile weapon if the target of
the attack is a SKAVENTIDE HERO that is
not a MONSTER.
In skaven society, the rear of a formation is a position
of honour and leadership. Not least, this is so that
skaven rulers can use their underlings as a living
shield.
