Overview
| Primary Military Basis | Hierarchical Mech Warfare |
| Core Combat Unit | Column |
| Common Command Structure | Column → Company → Ward → March |
| Primary Combat Platform | War Mechs |
| Operational Philosophy | Flexible Combined Command |
At the center of nearly every military organization in the Core stands the War Mech. Though supported by conventional forces such as infantry, vehicles, aerospace units, and vast logistical networks, mech formations remain the decisive arm of modern warfare. Across the Core, battles are won and lost by the ability of one side's mechs to defeat the other's.
The military structure of the Core evolved around this reality. For centuries, militaries have organized their forces into scalable formations capable of coordinating everything from small frontier patrols to massive interstellar campaigns. While technology and battlefield doctrine have changed dramatically over time, the underlying organizational principles have remained remarkably consistent.
From mercenary companies and planetary militias to the immense armies of the Great Houses, military formations are built upon a common hierarchical framework designed to provide clear command, operational flexibility, and effective coordination across vast distances. At every level of that hierarchy, the primary purpose remains the same: to deploy, support, and command mech forces in battle.
Structure and Hierarchy
| Formation | Typical Size | Typical Responsibility |
|---|---|---|
| Column | 4 Mechs | Tactical operations |
| Company | 12 Mechs | Local operations |
| Ward | 40-50 Mechs | Regional operations |
| March | 100-200 Mechs | Planetary campaigns |
| Brigade | 1,000-2,000 Mechs | Multi-world operations |
| Division | ~10,000 Mechs | Sector command |
| Corps | 50,000-75,000 Mechs | Major border or theater command |
| Command | 200,000-350,000 Mechs | National military authority |
The Column
Typical Strength: 4 Mechs
The fundamental combat unit of modern mech warfare is the Column.
A standard Column consists of four mechs operating under a single commanding officer, supported by technicians, logistics personnel, and other attached specialists. Though small by military standards, a Column possesses enough firepower, mobility, and tactical flexibility to operate independently for extended periods.
The four-mech structure has endured for centuries because it provides an effective balance between command simplicity and battlefield capability. A Column is large enough to perform multiple battlefield roles simultaneously while remaining small enough for a single commander to coordinate effectively under combat conditions.
Throughout the Core, Columns are routinely assigned a wide variety of missions, including reconnaissance, patrol operations, raiding actions, defensive deployments, urban combat, and direct assault operations. Many frontier worlds rely upon a handful of Columns as their primary military force.
Because of their versatility, Columns form the foundation of nearly all military organizations in civilized space. Larger formations are built by combining multiple Columns under increasingly senior commanders.
Reinforced Columns
Typical Strength: 6-8 Mechs
In high-risk or specialized operations, commanders may deploy Reinforced Columns consisting of six or, more rarely, eight mechs.
These formations are particularly common among mercenary companies, frontier militias, assault units, and irregular military forces. The additional mechs provide greater battlefield endurance, tactical flexibility, and redundancy, allowing the formation to absorb losses while maintaining operational effectiveness.
While Reinforced Columns possess substantially greater combat power than standard formations, they also require more logistical support and are generally less mobile. As a result, most professional militaries continue to regard the four-mech Column as the ideal balance between flexibility, firepower, and command efficiency.
Companies
Typical Strength: 12 Mechs Composition: 3 Columns
Three Columns are typically organized into a Company.
A standard Company fields approximately twelve mechs supported by dedicated maintenance crews, logistical personnel, tactical staff, and command elements. At this level, a formation begins to possess the resources necessary to sustain prolonged military operations without relying heavily upon outside support.
Companies are widely regarded as the smallest formation capable of conducting independent campaigns. A Company may be tasked with defending a frontier settlement, suppressing a local insurgency, conducting anti-piracy operations, or securing strategic objectives on a lightly defended world.
For many smaller powers and frontier governments, a single Company represents a significant military force. Even among the Great Houses, Companies are frequently deployed independently to patrol borders, respond to emergencies, and reinforce threatened regions.
The term mercenary company originates from this organizational level, though actual mercenary formations vary enormously in size. Some independent outfits field only a single Column, while the largest Greater Mercenary Companies command forces rivaling those of entire national militaries.
Reinforced Companies
Some militaries and mercenary organizations employ Reinforced Companies consisting of sixteen to twenty mechs. These formations are most commonly used for independent operations, frontier deployments, and specialized assault missions where additional firepower or operational endurance is required.
While Reinforced Companies offer greater battlefield flexibility than standard formations, they also require significantly more logistical support. As a result, most professional militaries continue to regard the twelve-mech Company as the standard organizational model.
Wards
Typical Strength: 40-50 Mechs Composition: 3-5 Companies
Several Companies combine to form a Ward.
A typical Ward fields between forty and fifty mechs supported by dedicated command personnel, logistical assets, and increasingly sophisticated coordination systems. At this scale, a formation possesses the resources necessary to sustain prolonged operations across large geographic regions while maintaining multiple independent combat elements.
Wards form the backbone of most military operations throughout the Core. Large enough to conduct offensive campaigns yet small enough to remain highly mobile, they represent the formation most commonly deployed when a government expects serious resistance.
A Ward may be tasked with securing a strategic region, defending a major population center, suppressing a large insurgency, conducting planetary offensives, or serving as the primary military force on a frontier world. Many military planners consider the Ward the smallest formation capable of exerting meaningful strategic influence over an entire campaign.
Because of their balance of mobility, firepower, and operational endurance, Wards are frequently described as the workhorses of modern warfare. Throughout the Core, most major military actions are ultimately fought and won by formations at the Ward level.
Marches
Typical Strength: 100-200 Mechs Composition: 3–5 Wards
Several Wards combine to form a March.
A typical March fields between one hundred and two hundred mechs supported by extensive logistical infrastructure, aerospace attachments, command staff, and conventional military assets. At this scale, a formation possesses the resources necessary to conduct independent military campaigns for extended periods without relying heavily upon outside reinforcement.
Marches are among the largest formations commonly encountered in active military operations. They are capable of launching planetary invasions, conducting prolonged offensive campaigns, suppressing large-scale rebellions, and maintaining control over entire regions of contested territory.
Unlike smaller formations, a March functions not merely as a combat force but as a self-contained military organization. Commanders at this level must coordinate logistics, aerospace operations, intelligence gathering, troop movements, and long-term strategic objectives in addition to battlefield engagements.
The deployment of a full March is often viewed as a sign that a conflict has escalated beyond a localized military action. On frontier worlds, the arrival of a March may represent the largest military force the local population will ever witness.
Military historians frequently describe the March as the smallest formation capable of independently conducting a planetary campaign from beginning to end.
Brigades, Divisions, Corps, and Commands
Beyond the March, military formations transition from battlefield organizations into strategic instruments of state power. These immense formations coordinate campaigns across multiple worlds, oversee vast logistical networks, and command military resources measured in the tens or hundreds of thousands of mechs.
Brigade
Typical Strength: 1,000–2,000 Mechs Composition: 7–10 Marches
A Brigade represents the first truly interplanetary military formation. Possessing enough combat power to conquer, defend, or occupy entire worlds, Brigades are commonly assigned responsibility for strategically important systems, major military campaigns, or clusters of frontier worlds.
Unlike a March, which typically focuses on a single campaign, a Brigade must coordinate multiple simultaneous operations while maintaining reserves, supply networks, and strategic flexibility. For many smaller powers, a Brigade represents the largest military formation they can field.
Division
Typical Strength: Approximately 10,000 Mechs Composition: 4–5 Brigades
Divisions oversee military operations across entire sectors of space. In addition to commanding multiple Brigades, divisional headquarters coordinate logistics, transportation, aerospace assets, industrial support, and long-term strategic planning.
Most sector governments maintain close relationships with divisional command staffs, as Divisions often represent the primary military authority within a region. During peacetime, they serve as the foundation of military readiness. During wartime, they become the operational centers from which major campaigns are directed.
Corps
Typical Strength: 50,000–75,000 Mechs Composition: 5–7 Divisions
Corps command major theaters of war.
Responsible for defending borders, coordinating large-scale offensives, and managing military operations across multiple sectors, Corps represent some of the most powerful military organizations commonly deployed by the Great Houses.
A single Corps may oversee dozens of active campaigns simultaneously. During periods of heightened tension, entire borders between rival powers may fall under the responsibility of a Corps commander.
Command
Typical Strength: 200,000–300,000 Mechs Composition: 3–6 Corps
The Command is the highest military formation maintained by most Great Houses.
Commands direct military operations across vast regions of space and frequently coordinate multiple Corps, fleets, industrial centers, and logistical networks. In practice, a Command functions as an entire military establishment rather than a conventional battlefield formation.
The military strength of a Great House is often measured by the number and quality of Commands it can field. Full Command-level mobilizations are exceedingly rare due to their immense economic and logistical requirements, but when they occur they can reshape the balance of power across the Core.
Battlestars
Typical Strength: Equivalent to 10,000–30,000 Mechs
Battlestars occupy a unique position within military organization. Though technically warships, their enormous size, aerospace capacity, logistical infrastructure, and command facilities allow them to function as independent strategic formations.
During major campaigns, a Battlestar may serve as a mobile headquarters for divisional or corps-level operations. Possessing the ability to transport, support, and deploy thousands of mechs across multiple star systems, Battlestars act as mobile fortresses capable of projecting military power far beyond the reach of conventional formations.
The deployment of a Battlestar is often regarded as a political statement as much as a military one, signaling that a Great House considers a conflict of exceptional importance.
Limited Warfare
Despite the immense military forces maintained by the Great Houses, true Command-level warfare is exceedingly rare in the modern Core.
The cost of transporting, supplying, repairing, and supporting hundreds of thousands of mechs across interstellar distances is staggering. Even the wealthiest powers cannot sustain large-scale campaigns indefinitely without placing enormous strain on their economies and industrial bases.
Political considerations further discourage total war. Major conflicts between Great Houses inevitably attract the attention of the Star Regent and the Stellar Conclave, both of which possess strong incentives to prevent wars from escalating into civilization-threatening disasters.
As a result, most military forces spend far more time defending territory than conquering it. House armies routinely conduct anti-piracy operations, suppress bandit activity, secure trade routes, protect frontier settlements, and respond to raids along the borders of civilized space. While limited conflicts between rival powers do occur, outright wars between Great Houses remain uncommon.
Most inhabited worlds also maintain local defense forces responsible for planetary security. These organizations vary enormously in size and capability, ranging from lightly equipped militias to professional military formations possessing their own mech units, aerospace squadrons, and armored forces. In times of crisis, planetary defense forces are expected to contain threats, protect civilian populations, and delay hostile forces until House militaries or mercenary reinforcements can arrive.
When disputes arise between major powers, direct military intervention is often avoided in favor of mercenary proxies. By employing independent mercenary companies, governments gain plausible deniability while obscuring the true origins of military operations. Raids, sabotage missions, border skirmishes, and territorial disputes can be pursued without openly committing House forces or risking a broader political crisis.
This reliance on mercenary forces has had a profound effect on military culture throughout the Core. While House militaries are generally larger and better supplied, many spend years performing garrison duty, security operations, and defensive assignments. Mercenary companies, by contrast, are frequently deployed to active conflict zones and high-risk operations. As a result, veteran mercenary formations often possess combat experience that rivals—or in some cases exceeds—that of their national counterparts.
This reality has shaped military doctrine throughout the Core. Most formations are organized not for total war, but for rapid deployment, limited campaigns, frontier operations, and the pursuit of strategic objectives without triggering a wider conflict.
Faction-Specific Hierarchies
Although military organization remains broadly standardized throughout the Core, command titles vary considerably between factions. These differences reflect centuries of cultural development, political tradition, and military philosophy.
A commander from the Union may immediately recognize the authority of an Imperial Guardian or a Protectorate Commandant, even if the titles themselves differ. While the names change, the underlying hierarchy remains remarkably consistent across civilized space.
Omnisphere Imperium
The Omnisphere Imperium preserves some of the oldest military traditions in the Core. Many Imperial titles are believed to descend from institutions that predate even the Golden Empire itself.
Imperial command ranks emphasize guardianship, continuity, duty, and stewardship. Officers are viewed not merely as military leaders, but as custodians of a legacy stretching back thousands of years.
Confederate Vanguard Union
The Union employs highly standardized military terminology focused on clarity, efficiency, and operational effectiveness. Its ranks reflect the Union's belief that military command should be practical, merit-based, and easily understood.
Due to the Union's military influence and the large number of former Union officers serving in the mercenary community, Union terminology has become the closest thing to a common military language throughout much of the Core.
Helios Sovereignty
The Sovereignty blends military authority with aristocratic tradition. Many senior commands carry noble or ceremonial connotations, reflecting the faction's dynastic culture and close relationship between military service and social status.
Within the Sovereignty, military rank is often viewed as an extension of noble responsibility and leadership.
Starcrest Protectorate
Protectorate ranks emphasize defense, guardianship, and service to the realm. Titles such as Warden, Commandant, and Grand Marshal reflect a military culture focused on protection rather than conquest.
Protectorate officers are traditionally viewed as guardians of the people and stewards of the territory entrusted to their care.
Orion Corporate
Corporate command titles reflect the Orion Corporate's administrative and technocratic worldview. Military leaders are often treated as managers of complex systems rather than traditional battlefield aristocrats.
Terms such as Marshal, Flag Marshal, and Prodirector reflect a culture that views warfare as a problem to be coordinated, optimized, and efficiently managed.
Mercenary Companies
Most mercenary organizations utilize Union-style rank structures due to their widespread recognition and practicality. However, individual companies frequently adopt unique titles, traditions, and organizational customs based on their history and culture.
Larger mercenary companies often develop military traditions rivaling those of the Great Houses themselves.
Comparative Command Titles
| Unit | Mercenary | Union | Sovereignty | Protectorate | Imperium | Corporate |
|---|---|---|---|---|---|---|
| Column | Lieutenant | Lieutenant | Leftenant | Armsman | Sentinel | Lieutenant |
| Company | Captain | Captain | Captain | Praetor | Vigilant | Captain |
| Ward | Major | Major | Major | Warden | Warden | Major |
| March | Colonel | Colonel | Duke | Commandant | Guardian | Marshal |
| Brigade | Brigadier General | Brigadier General | Brigadier General | Spartan General | General Viceroy | Second General |
| Division | General | General | General | General | General | General |
| Corps | Varies | Field Marshal | Lord Marshal | Grand Marshal | Subcommander | Flag Marshal |
| Command | - | First Commander | Lord Commander | Oberst Commander | High Commander | Commodore |
| Supreme Commander | - | High Minister | Archduke / Archon | Herzog | Imperator | Prodirector |
Mercenary Organization
While most mercenary companies broadly follow the same organizational principles used throughout the Core, few adhere to them rigidly.
Smaller mercenary outfits often maintain informal command structures based on seniority, reputation, battlefield experience, or contractual authority rather than formal military rank. Larger organizations frequently employ reinforced Columns, irregular Companies, temporary task forces, and specialized detachments tailored to the needs of individual contracts.
The greatest mercenary companies rival national militaries in both size and sophistication, while the smallest may consist of little more than a handful of mechs operating under a single commander. This flexibility is often regarded as one of the greatest strengths of the mercenary profession.
Conventional Attachments
Although military formations throughout the Core are typically classified by their mech strength, few military organizations consist entirely of mechs.
At smaller scales, such as Columns and Companies, conventional support is usually limited to maintenance crews, logistics personnel, reconnaissance assets, and transport elements. These units exist primarily to keep mech formations supplied, repaired, and combat-ready.
As formations grow larger, substantial conventional forces become increasingly common. Wards and Marches often include attached infantry formations, armored vehicle companies, artillery batteries, aerospace squadrons, engineering units, and logistical support organizations. At the Brigade, Division, and Corps levels, these conventional forces may number in the tens or even hundreds of thousands of personnel.
In most military formations, conventional units are organized around supporting mech operations rather than operating independently. Infantry secure objectives captured by mechs and help maintain control of contested territory, armored vehicles provide fire support and transportation, aerospace units extend reconnaissance, air cover, and strategic mobility, while engineers and logistics personnel sustain military operations across vast distances. Despite their size and importance, conventional forces are generally viewed as supporting elements rather than the centerpiece of military power. Throughout the Core, it is the mech formations that remain the decisive arm of warfare.
As a result, military strength throughout the Core is traditionally measured in mechs rather than total personnel. References to a Company's, Division's, or Corps' size almost always describe its mech complement and do not include the extensive conventional forces attached to it.
This distinction reflects the realities of modern warfare. Conventional forces may support a campaign, occupy territory, and sustain military operations, but it is usually the mech formations that decide the outcome of a battle.
Cultural Importance
Military organization is deeply woven into the culture of the Core.
Across civilized space, military terminology influences politics, government, commerce, and everyday life. Many civilian institutions borrow organizational concepts from military structures, while military service remains one of the most respected professions within most major powers.
The influence of military culture is particularly visible among the Great Houses. Generals, marshals, and veteran commanders frequently transition into political leadership, while many rulers maintain military titles alongside their civilian authority. Even in societies that value commerce, culture, or science above warfare, military service is often regarded as evidence of discipline, competence, and leadership.
This influence extends beyond national militaries. Mercenary companies, frontier militias, planetary defense forces, and civilian security organizations all draw heavily from the same traditions. As a result, a commander from one end of the Core can often understand the structure and responsibilities of a military organization from the other.
For many citizens, the military hierarchy represents more than a system of command. It is viewed as one of the institutions that allows hundreds of worlds to remain connected, defended, and stable despite the vast distances separating them.
From the smallest four-mech Column to the immense Commands that coordinate military operations across entire regions of space, the military organization of the Core reflects a civilization built upon duty, discipline, and the belief that order is the foundation of peace.
