So, this is mostly a "how do you?" more than a how does the book say, but I am curious. How do you deal with enemy units health in combat? On the one hand, I could see a large group of Dominate schmoes using something akin to Magnitude, rather than keeping track of Wounds and Health, but smaller groups, say squads, only seemed to work with Eldar, where their numbers needed a boost against Space Marines, and Dom don't. When your players fire at NPC grunts, do you treat them as characters, tracking health and what have you, or like Comrades, who die very easily? If they get to be more like your players, and less like their comrades, why? If every other soldier is durable, why are Comrades so tissue paper?
Granted, this assumes that I am reading rules right, and three real hits will kill a Comrade, barring special things (Ogryn Comrade). They can take cover, and whatnot, to hopefully not get hit, but their bullet-sponging abilities seem lacking. Are enemy soldiers as squishy in your games, or are all Comrades just that much redshirt/whiteshield?
