Tyretian writes: If you want to give a unit an attack bonus vs. villagers, you'll have to use one of the extra armour and attack classes (31-35), and give all kinds of villager at least 0 in that armour class, then give your chosen unit the same numbered attack class. Make sure you remember which one you use and make sure you do it on all the different villagers (Farmer, Lumberjack, etc).
