Commissars are ruthless officers embedded throughout the Astra Militarum, charged with maintaining the morale, discipline, and loyalty of their regiment. With the power to summarily execute any soldier found wanting in their duties, they are feared, brooding figures. A Commissar's devotion to the Imperium is without doubt, and they fight with fanatical bravery – inspiring the same fervour in those who fall under their watchful gaze.
