[@Eisenhorn] Yeah, if anything the Imperium's psykers are some of the least stable and most prone to daemonic possession and whatnot (not counting untrained psykers of course, because they don't even know they have powers.) We need to see that at some point, our mixed regiment standing to attention and causing a commissar to have a heart attack due to the number of psykers we have. That is, quite a smart idea actually. Provided you aren't BLAM'd first. Since I imagine said horror monster is probably able to rip apart/blast with mindbullets most things it is fighting (daemons are no joke, unless you play Wardian Grey Knights) and generally turn everything into pulp. But yeah, an interesting strategy - given that all sensible people would run from that.
