Editing Warhammer 40,000/3rd Edition Tactics/Witch Hunters (section)

===Heavy Support===
*'''Exorcist''' - Not the tank chewing murder machines they were in fourth edition, but still quite good at their role and more importantly the only dedicated anti-armor unit you have. An important note is that these missile spewing behemoths can remain fairly effective while on the move, outclassing a similar unit like a predator annihilator. Take advantage of this and don't be afraid to reposition if need be. As always they are best taken in pairs to mitigate the randomness of their damage.
*'''Immolator''' - Your sisters need to get within 12", and emperor knows they're not getting there on foot. As a transport its basically an expensive Rhino that will draw more antitank fire. It starts to shine when taken en masse. A wall of flame belching AV11 metal can quickly overrun enemy positions.
*'''Orbital Strike''' - Congratulations, you just lost a heavy support choice.
*'''Penitent Engine''' - The Sisters Repentia of the heavy support class. Sure it looks devastating in close combat, but with AV10, open top, and holy rage do you actually think its going to get there? If you're really good with getting units who have difficulty getting to where they need to be, go ahead and take it, but...there's easier ways to do the same thing that this does.
*'''Retributor Squad''' - A solid choice when outfitted with 4 heavy bolters. Unfortunately it suffers from the crippling disadvantage of not being an exorcist. Not my first choice but they certainly wouldn't go amiss in the right situation. Never walk them anywhere, ever.
