Elites

Dreadnoughts, valiant warriors who have suffered so much physical damage that they cant be put back together, and are instead interred into a life support system so that they can fight on.
Iron Priests are the Techs with a 2+ save and a Thunder Hammer you have to love this guy.
Scouts, these are seasoned veterans that are happier operating by themselves and appear when least expected behind your enemies lines to cause mayhem.
Wolf Guard in terminator armour can carry serious amounts of firepower or close combat support for the boss, one in three can carry an assault cannon! Bit of a shame that they will never teleport.
