A warrior poet is a person who is both a warrior and a philosopher. Despite (or, perhaps, because of) the fact that they kill people for a living, they've put a lot of thought into life and death. They often funnel these thoughts into art -- either to help them sort out their feelings for themselves, or as a way to express their feelings to others. Other warrior poets simply talk about such things with their fellow soldiers -- it's not uncommon for a grizzled old Sergeant Rock to lecture the New Meat or Ensign Newbie on the philosophy of combat. Some become warrior poets by necessity, if their only other option is to become a Shell Shocked Senior.
