Of course, the Valhallans are pretty great too, especially Commander Chenkov. He so perfectly exemplifies the Imperium's attitude that Guardsmen are about as valuable as the las guns they're carrying…actually, scratch that. Guardsmen are less valuable than las guns. You can recover a las gun from a corpse and pass it on to the new recruits, can't do much of anything with a corpse. The Valhallans put the grim in grim dark.
