Titan Legions (1994), p20 — Titan Battle Groups

Scout Titans such as Warhounds have not been organised into battle groups since the excesses committed by Senior Princeps Esau Turnet's Deaths Head Scouts, part of the Traitor Legio Mortis, during the Horus Heresy. Instead Scout Titans operate in pairs and these teams are attached to battle groups or other large formations as required.
