Basically, my two Battle Sister squads will advance to get into range for their guns under cover fire from the Inquisitor Lord and Retinue. I will use the "Word in your Ear" rule for the Callidus to move a squad out into the open for the first turn so I can blast away at them with Heavy Bolters and hopefully weaken them before they can do much. Then, my Callidus will come in from reserve and toast some brains and charge, probably killing most of whatever squad it was. By this point, my Battle Sister squads should be in range to use thier weapons and mop up whats left.
