Fall of Cadia - Wrathful Crusade Formation

This looks like an interesting formation to run.  It contains Celestine, Greyfax, a space marine captain, 2-4 Crusader squads, 1-2 assault squads, 0-1 Sternguard squads (the space marines have the Black Templars chapter tactics), and a Militarium Tempestus squad.  Maxing the number of units in the formation while applying no upgrades, so you get the Collective Fanaticism rule, costs 1040 points.  This will give every unit in the formation, Zealot, in addition to the Crusader Rule, and the ability to re-roll charges, and possibly get Furious Charge when you roll a 10 or more on the charge distance.

With the addition of dedicated transports, and unit upgrades this can formation can be set up for alpha striking, and/or objective holding.

Add in Celestine's Saintly Blessings, you either get troop units have a 6+ FNP,  or elite units get Furious Charge and Counter-Attack, once per game.

Using Greyfax's Aura of Oppression psychic power will prevent a unit from moving away quickly, or overwatching any of the units within charge range.

Additionally, the Space Marine Captain can take any of the Ecclesiarchy Relics.
