Many of Knights of the Chalice's quests include a battle or two in which your party gets supported by AI-controlled allies, as in this video where a village is being attacked by Frost Giants and the party must join forces with a group of Knights. Many of these friendlies have so few HP that they're practically nothing more than glorified cannon fodder, but are nonetheless useful since getting the enemies attention away from your own characters (even for just a few turns) can spell the difference between life and death in a challenging RPG like KotC.
