I simply use them as shields more than anything. Because they will often march forward, and get the attention of whatever I am fighting - so they focus on it - cast Guardian Angel and Magic Screen on it - so it lives as long as possible. In the mean time I have my mage go to town with spells like fireball, nuclear blast, firestorm, asphixiation (sp) - then whatever is left alive comes at my warriors and gets sliced to pieces.
