Warrior
The Warrior was one of several NPC Classes introduced in Dungeons & Dragons 3rd edition.
Unlike commoners, they generally have some ability to fight back if attacked, but they're even weaker than the fighter, since they don't get bonus feats.
Typical warrior NPCs include guards, soldiers, local thugs or common people who have learned to fight in order to defend their home to a certain degree. A fallen Paladin is almost functionally identical to a Warrior.
