As far as I know, JT, no, no doctrines. The IG allies, if you run a pure Daemonhunters list is relegated to plain vanilla platoons, and I think maybe 1 leman russ? Don't have it right here with me, but that's why I have an IG army, with an Inquisitor ally, so that I can use doctrines and what not, but have an Inquisitor with it. Maybe I've got that wrong, but that was the reason I didn't go with an Inquisitor army, then use IG allies....
