The Imperial Host is split up into three primary, assigned divisions: The Army, The Guard, The Institute and a fourth, unassigned and un-named division. Though these divisions all operate independently, their hierarchies do converge at the higher levels, most notably among the Red Viziers.

The Red Viziers are individuals selected to sit alongside the Grand Vizier on the Divan and represent the interests of their particular division. There are two assigned to The Army, one to The Guard, and another to The Institute. While there are a number of things differentiating the Red(also "Lesser") Viziers from the Grand Viziers such as authority, the most notable and important difference is in the manner in which their positions are achieved. A Red Vizier may attain such a role through one's own merit alone and steady ascension, whereas a Grand Vizier could more aptly be addressed as Holy Vizier, as they are appointed by the Emperor's will alone and are therefore considered sanctified.

The Army is the largest and most heavily funded branch of the Imperial Host. In the earliest days of the Empire the Army was the whole of the Host. It was initially comprised of the combined forces that had united under Gerra's banner of holy conquest, and then subsequently the assimilated militaries of the conquered city states after the battle of Ninagal. This led to a confusing and tense re-organization. Gerra's initial force comprising primarily of the united Abtati loyalists and the city states being of Kalitian lineage. The history alone between these two species made the Host's reorganization an arduous undertaking in itself, with Kalitians being forced to answer to Abtati, who in times passed they'd had not thought twice about enslaving or murdering.

As we come to the current day, the Imperial Army is efficient, effective and diverse in not only culture but also utility. Though the enmity of old still exists, even blatantly at times, the Abtati leadership of the military, having forgone any inclination toward a vindictive command structure, ensured room for Kalitian advancement and maintained a status quo of treatment across the board. Over time this fairness did not go without notice, and within the ranks of the Army much of this old enmity has been put to rest and even replaced with comradery.

Though many lines have begun to overlap with a now standing army, but each of the races and city states typically bring their own unique contributions toward military support. Infantry, light calvary and cataphract divisions are evenly distributed. The Abtati primarily specialize as assassins, calvary-archers or sorcerers. The Kalitian city of Annuakat send lightweight and agile chariots to war. The mages in Thakath specialize in blood-magic, and use their powers to augment the ferocity of imperial soldiers. Not only this, but their subjugation of monstrous wild beasts have yielded them formidable chariots of their own in the forms a great, armoured rhinos.

Within The Army there are two main groups: the standing army, and the reserve force. The standing army is made up of full time soldiers who spent much of their time on assignment. The reserve force is made up of soldiers who take extended leaves to live as a civilian, and though they are still on military payroll they take a significant pay-cut during times on reserve. They are also still required to attend training exercises several times a month while on leave.

The Army's training program is rigorous and rounded. Ranging from obstacle navigation to hand-to-hand combat, standing warriors of the Imperial Army train daily in order to maintain their prowess.

The Guard was a division that came about after the structure of the Army itself had been firmly established and, due to the fiscal benefits, enlistment became more and more popular. Because of this it had become more difficult to document and justify Army costs, and relations between the military and treasury had become strained. As such, a new division was deemed the next logical step to address not only fiscal but logistical issues as well.

The Guard itself is split up into several detachments. While cities such as Mamsis, Tyria and Kherkana maintain their own local guard, Ragash, Annuakat and Salitra's standing forces have all but been assimilated into the Imperial Guard. They are responsible for the protection of a city's emir, and they are also assigned to the manning of city gates and patrolling of the walls, the protection of Imperial palaces as well as their occupants and other Imperial structures of importance such as dockyards or storage facilities. Though it is typical for nobility to have their own private protection, The Guard has also been deployed as noble escort in the past as well.

Their numbers are significantly fewer than those of The Army, and because of this The Guard is more properly funded and usually better equipped. Though a Guard is not granted to option of being a reservist, they are not only better funded as a division but they are also better paid individually. They are however subjected to a training regime that is no less intensive than that of The Army.

The Institute was another division that came about alongside the creation of The Guard and operate almost as a sub-division of them as they work so closely with one another. They are however on a separate payroll and pay-grade. The Institute is likely the most diverse division as far as career options and pay-scale go, given that their responsibilities range from not only the enforcement of Imperial law, but the prosecution and imprisonment of criminals.

In The Institute, the most commonplace profession is an Enforcer, someone resembling an augmented infantryman patrolling city streets arresting criminals such as thieves or petty miscreants. Then there are riot protocols, gang protocols and heist protocols where these same Enforcers take on other, heavier roles. This ranges all the way to assassination prevention, employing some of the Empire's own most deadly assassins. Institute combatants, for the most part, resemble their Army counterparts though they display a far more personalized flare.

The Institute also employs various administrative positions surrounding the Empire's legal structure. Their Emperor's approach is one of far more fairness than most are used to, and the growing complexity of his policies and laws reflect this.

The Fourth Division has arguably always been. Designated "unassigned," units are associated with this division as blanket term only. None of them share pay-roll. Some of them hardly qualify as an Imperial unit. Most are specialized units with negotiated pay-roll and elevated levels of autonomy. The Immortals and the Sipahi are examples of these.

The intent of the Imperial Host is to:
a) safeguard the lands and populace of the Empire, and,
b) facilitate the expansion of the Empire.

To this end, in peacetime, the army is significantly reduced and many of the active members are garrisoned within the various cities to police these cities and the surrounding areas. There are also regular patrols of the Empire's borders and inner territory. Even in peacetime, the likelihood of conflict is still great as there are various peoples and tribes who do not subscribe to the Empire's influence, and often cause unrest among the outlying tribes and villages who do.

A warriorhood mentality his heavily encouraged amongst those who participate in the army's efforts, and often this mentality remains even with those who return to their homes, inspiring them to practice and hone their martial prowess for when the next need arises.

And though there is still a significant standing military at all times, in wartime, these garrisons are drawn from and great numbers re-conscripted, and a great army is assembled.
