AL LRRP team unleashing daemons

Grenada Reconquest- Iberian Campaign- Iberia-  An Alpha Legion long range recon patrol team including a sorcerer later identified as the arch heretic Kallis assault a Imperial Supply depot while Kallis opens a small warp rift and unleashes a force of daemons to run rampant behind imperial lines.  These terror tactics the Alpha Legion used on Iberia also had the advantage of tying up an inordinate number of forces from front line duty to protect the ground already taken.  A result of which was the slowing of the advance.
