Here are some great pictures of thier "battles". You will note that some of these clanks are holding thier arms behind thier back-it's thier "honor" system, indicating they took a sword blow to the arm, and are now maimed. (Of course, I don't know how 'maimed' a person can really be when he has been lightly tapped by some dungeons and dragons geek with no martial arts training.....)
