Alpha Legion - Legion Command Hierarchy: As with so much concerning the Alpha Legion, precise definition of their command structure cannot be determined with certainty, but certain patterns can be deduced as -- if not constant -- then repeated enough to have been deemed important. The first of these is specialisation. In any given deployment, a chain of command was obeyed unquestioningly, but this chain of command was a fluid one, both conditioned and highly decentralised in its manner.While a force would be notionally under the command of an officer such as a Captain, the authority held by specialists in particular, such as Siege Masters or Vigilators, was deferred to as a matter of course and was regarded as absolute and not to be questioned in their area of expertise. Likewise, each unit within the XXth Legion was expected to operate as a self-motivated and self-governing "cell" without need of exterior command, and expected to display initiative and pursue its part in the wider battle plan under its own cognisance and in any way it judged to be expedient.Such was the emphasis on unity of action and initiative the Alpha Legion placed on its warriors that the battlefield co-ordination and responsiveness to changing circumstances that the Alpha Legion displayed was arguably superior to that of any other of the Legiones Astartes. The Alpha Legion's commanders seldom were observed to operate as champions or warlords in the conventional sense as might be expected of the Legiones Astartes, craving it seemed neither personal glory nor the experience of sublime clash of arms.Instead they were wont to observe the battle unfold impassively, matching the patterns of force and bloodshed it revealed, intervening only when needed by issuing orders that would tip the outcome in the Alpha Legion's favour or by direct participation, striking personally at the point of vulnerability where they would inflict the greatest damage.In terms of honourifics and titles, the Alpha Legion seemed to have used a shifting set of terminology to convey authority and role. At times the Alpha Legion appears to have deliberately aped the systems used by other Legions (such as the Sons of Horus and the Blood Angels) although whether this was done to incorporate a proven pattern of organisation as part of a particular strategy or as some form of mockery remains unknown.Aside from these patterns, close scrutiny of the records reveals several distinctive additional divisions of command not shown by other Legions. One such unique title known to have been used by the Alpha Legion was that of "Harrowmaster" or Jhariuk as the leading commander given overall control of all Alpha Legion forces in a given war zone was known.Although their normal rank might vary, it was the task of the Harrowmaster to keep track of encompassing the shifting events of a conflict in minute detail and shape the actions of the Legion's forces accordingly, creating and aborting battle plans and stratagems with bewildering speed.The position of Harrowmaster was known to be held as a supreme accolade by the Alpha Legion, and their infamous skill at battlefield control was highly regarded (even as the Legion itself was often mistrusted) by the commanders and strategists of the other Space Marine Legions.It is noteworthy that the Harrowmasters were among the few of the Legion, save its Equerries, whose personal names are left to the open record, although whether they have any basis in reality or are merely guises worn by a single warrior or perhaps a series of individuals remains unknowable.
