Centurion (Space Marine Rank) - General Consul Types: The following are the most common examples of officers of what would be considered centurion rank found in the Space Marine forces of the Great Crusade, although many others existed in particular Legions.Consul Chaplain - Legion Chaplains ensured the spiritual well-being of their Legion and enforced the psyker ban in accordance to the Emperor's Decree Absolute rendered during the Council of Nikaea. These officers were picked from those Space Marines who were the most steadfast in their duties, and who had demonstrated the strongest loyalty to their Primarch and to the Emperor.Legion Champion Consul - A Legion Champion's sworn task was to hunt down and slay the commanders and heroes of an enemy force in single combat. Armed with the finest weapons available, these deadly transhuman warriors embodied the honour of their Legion.Legion Consul Praevian - A Legion Consul Praevian was a unique position within a Space Marine Legion who were often assigned to serve as the commander of a cohort of Battle-Automata, the walking engines of death forged by the Legio Cybernetica and bonded in service to an individual Space Marine Legion. These cohorts were comprised of either Castellax or Vorax-class Battle-Automata.Legion Delegatus - A Legion Delegatus was a mid-ranking Legion officer, such as a Centurion, tasked with a specific mission by Legion high command and formally deputised to act in all matters with the full weight of their commander's authority. As such, they could mobilise the Legion's resources to the full, deploy its assets and, if performing a mission of vital strategic worth, assemble a strike force of chosen warriors.Consul Librarian - The Legion Librarians served as battle psykers and the keepers of the Legion's records, battle honours and chronicles. The Legion Librarius departments were disbanded after the Council of Nikaea on the order of the Emperor.Master of Signal - A Master of Signal was commonly attached to the forward elements of a Space Marine assault, providing vox and cogitator-based communications support across the wider warzone, and was capable of calling down a pinpoint bombardment from either orbiting fleet assets or static artillery positions nearby, engulfing the foes of Mankind in flaming destruction.Moritat - A Moritat was an unofficial designation given to certain Astartes of the ancient Legiones Astartes who displayed suicidal urges and a blatant disregard for overall combat doctrine. Operating independently on the battlefield, these individuals were often employed as efficient shock assault troops and assassins. From its earliest days, the Raven Guard Legion employed more Moritats than did many others. The individuals assigned to this duty were often those considered extreme in their methods even by the cold-blooded Xeric (the original Terran members of the XIXth Legion) and they were often used -- willingly -- to undertake missions from which they were not expected to return. This bygone rank no longer exists amongst the Adeptus Astartes of the 41st Millennium.Legion Vigilator - Highly skilled as watchers and hunters among their brethren, Vigilators were the eyes of their Legion on the ground, their wisdom paramount in scouting out the foe's disposition and strength, and determining the best place to strike. Theirs also were the arts of sabotage and assassination, and while some Legions were more inclined to such subtleties than others, all saw their military value.Forge Lord -  The Forge Lord served as a senior officer among the Legion's Techmarines.Primus Medicae - High officers of the Legion Apothecarion, the primus medicae of a Legion held the onerous duties of both ensuring the battle-readiness and physical well-being of their battle-brothers. This was an authority which none but a primarch or his chosen deputy could overrule, and such warriors were dedicated to preserving the gene-seed of the Legion from loss or contamination at any cost, even that of their lives. The primus medicae were skilled in all the fields of medicae relevant to the biomedical care of Astartes on and off the battlefield and the creation of new Space Marines for the Legion using the accelerated maturation techniques in use at the time of the Great Crusade.Siege Breaker - The wreckers of cities, the bringers-down of fortress walls and the shatterers of strongholds, Siege Breakers were mid-ranking officers of the Legion whose tactical specialty was precisely-applied destruction against strategic targets. Placed often in command of armoured spearhead assaults and frontline artillery units, they preferred to closely observe their work, rather than sit back behind the lines, and so were deadly efficient in adapting their force's attack patterns from moment to moment.
