Witch Hunters have the most unpredictable and crazy units in the Imperium and i've decided to bult a small army just around them instead of usually including them in a regular SoB force.
Inquisitor w/Inquisitorial Mandate, Power Stake, Inferno Pistol, Scourging psykic, hexagramatic ward
2x Warriors w/Plasma gun, melta gun
1x Acolyte w/Bolter stake-xbow, carapace armour
Priest w/carapace armour, brazier of Holy Fire, las pistol, ccw
7x Storm Troopers w/Flamer, the priest
7x Storm Troopers w/meltagun
2 x Penitent Engines
6 x Arco-flagellants
6 x Arco-flagellants
Haven't given it a go yet, but I think it'd be fun. The Mandate is there for when (if) the crazies get into hth (screened for a short time by the Troopers). I'd expect the PEs to be destroyef first on turn 1 or 2, at least allowing the flachellants to get close; their high T and inv save should get them close enough to assault and obliterate a few squads. The anti-psyker gear is there just because... the models.
