Usually celtic longswords have very large lethality, but are a bit unwieldy to use, hence a bit lower attack rating. Nevertheless the higher lethality usually is better than higher attack rating.

Actually attack factor is a product of both the unit's skill and the weapon type while lethality is a product solely of the weapon.
