Army Order of Battle

Organization and strength

The Imperial Army organizes surface forces around standardized formations, specialist establishments, and mission-specific attachments. A formation's designation identifies its level and function; its actual strength depends on its assigned personnel, equipment, and readiness. No unit size alone guarantees the capture of a district, city, or planet.

Strength returns distinguish fighting personnel, command personnel, vehicle crews, support staff, and droids. A commander already included in a subordinate unit is not counted again at the next level. Authorized strength, actual strength, and personnel available for the operation are reported separately.

Command hierarchy

Numbered Army → Sector Army → Systems Army → Army → Corps → Battlegroup → Regiment → Battalion → Company → Platoon → Squad or Section.

The twenty Numbered Armies are Oversector-level commands, distinct from ordinary field armies. Below the territorial commands, four subordinate formations are a common organizing principle, not a rule that every specialist unit has identical composition or headcount. Headquarters, support establishments, and attached forces must be accounted for explicitly.

Squad and section

Line Squad

The standard line squad has eight soldiers and a sergeant: nine personnel in total. The corporal is selected from the eight soldiers and serves as deputy, rather than adding a tenth person. The squad provides general-purpose infantry for patrol, security, attack, and defense. A light repeating blaster may be allocated to one soldier as the squad support weapon; equipment returns specify the actual loadout.

Heavy Weapons Squad

Organized around crew-served repeating blasters rather than a uniform issue of rifles. Weapon teams may require two or three personnel according to the weapon. The establishment records the number of weapons, their operators, and ammunition carriers; the squad's personnel do not each count as independently operating its full heavy armament.

Sharpshooter Squad

Combines precision marksmanship with additional individual skills, including demolition and specialist field tasks. Mission duties are allocated according to competence. It is not merely a collection of identical long-range riflemen: equipment and leadership arrangements must support the assigned reconnaissance, precision-fire, or specialist mission.

Engineering Squad

Provides technical skills for obstacle clearance, demolition, repair, and access through difficult terrain or structures. Specialists carry mission-appropriate tools, sensors, and stores alongside personal weapons. Available equipment determines whether the squad can perform a particular engineering task; its title is not a substitute for transport, explosives, or specialist machinery.

Repulsorlift Squad

Combines an infantry element with two light transport vehicles. Infantry, vehicle crews, and specialist communications positions are listed separately, and embarkation must respect available seating. The transport element supplies mobility rather than turning all passengers into vehicle crew. Dismounted infantry and the vehicles may receive different tasks while remaining under coordinated command.

Heavy Weapons Repulsorlift Squad

Uses armed transports to provide greater supporting firepower. Depending on the equipment, weapons may be vehicle-mounted or capable of dismounted operation. A transferred weapon is recorded with its current crew and location; it cannot fire simultaneously from the vehicle and a ground position.

Scout Lance

A scout lance contains five scouts, including its sergeant, with suitable reconnaissance vehicles. Individual speeder bikes are a standard arrangement; alternative vehicles require compatible crew and seating. Scouts emphasize observation, reporting, and mobility, and are trained to maintain their mounts. Heavy combat vehicles are not interchangeable with scout mounts solely because both can move across the battlefield.

Armor Section

The basic grouping used to build armor platoons. A conventional section contains two light or medium tanks with three-person crews, or one heavy tank with a four- or five-person crew. Other vehicle types require their own approved crew establishment. Tank crew totals are not infantry strength, and the section does not automatically include a separate dismounted squad.

Artillery Section

The conventional section operates one medium or heavy piece with an eight-person establishment, or two light pieces with four personnel each. Selected equipment may require a different approved crew. The section's weapons, transport, ammunition, and observation arrangements are recorded separately. Artillery includes appropriate direct-fire and indirect-fire systems; not every piece can perform both roles.

Platoon

Line Platoon

Four nine-person line squads, a lieutenant, and a sergeant major give a baseline of 38 personnel. The lieutenant commands the platoon and the sergeant major assists with execution and coordination. Additional weapon teams or vehicles are attachments, not silently included in the baseline.

Assault Platoon

Also termed a heavy-weapons platoon, this formation combines two line squads and two heavy-weapons squads under the platoon command element. Its baseline is 38 personnel. Additional weapon details can raise strength to 41–47; the actual establishment identifies which teams have been added. Its purpose is concentrated infantry firepower, not simply a more aggressive name for a line platoon.

Repulsorlift Platoon

Coordinates four repulsorlift squads with command vehicles and a maintenance/resupply element. Its returns distinguish vehicle personnel from any infantry carried for another unit. Seats, crew positions, command communications, and recovery support determine the actual vehicle establishment; embarked troops must not be counted both here and in their parent infantry platoon.

Heavy Weapons Repulsorlift Platoon

Coordinates four heavy-weapons repulsorlift squads with command and support arrangements appropriate to their armed vehicles. It provides mobile supporting fire and can support tank or infantry formations. Its weapon mounts and dismountable systems distinguish it from an ordinary transport-oriented platoon.

Armor Platoon

A standard armor platoon is organized into four sections, fielding either four heavy vehicles or eight light or medium vehicles. The same structure is used for walker and other armored formations, although crew requirements vary by vehicle. The platoon lieutenant leads from a LAVr QH-7 Chariot command speeder.

Each platoon is supported by a Heavy Transport Vehicle and an HTV-M Mobile Workshop. Their fourteen mechanics and technicians keep the platoon's vehicles supplied, maintained, and ready for action. When a section operates on its own, it continues to draw support from its parent platoon.

Scout Platoon

Combines two line squads with a ten-scout mounted component. A lieutenant replaces the command lance's sergeant, while a sergeant major directs the infantry component, producing a baseline of 29 personnel. This mixed formation differs from the all-mounted 22-person scout establishment used by special-missions companies.

Artillery Line

The artillery equivalent of a platoon contains four sections: four medium/heavy pieces or eight light pieces. Its standard personnel establishment is 38, including its section and platoon command arrangements. Fire missions require suitable observation, communications, ammunition, and target information.

Special Missions Platoon

Combines two sharpshooter squads, one heavy-weapons squad, and an engineering squad with platoon command: 38 personnel. Teams may be reorganized for a mission while retaining accountable personnel and equipment. Specialist duties do not imply unlimited capability or exemption from support requirements.

Company

A company is normally commanded by a captain. The standard line company has four platoons totaling 152 personnel, five company command/staff positions, and 23 support personnel: 180 people before separately recorded droids or augmentation. Staff responsibilities include deputy command, logistics, medical support, and technical support.

Line Company

Four line platoons supported by the company headquarters and service element. It can undertake extended operations when adequately supplied; its endurance depends on the mission and available support rather than a guaranteed number of days.

Assault Company

Two assault platoons and two line platoons, with company command and support. Depending on attached weapon details, the platoons account for 152–170 personnel and the complete company for 180–198. It combines maneuvering infantry with stronger crew-served firepower.

Repulsorlift Company

Combines two repulsorlift platoons with two infantry platoons for mounted movement and dismounted action. Command and support accompany the mobile force. Transport crews and passengers are separate components, and a vehicle's seating capacity constrains the force it can actually carry.

Attack Armor Company

Combines three armor platoons with a heavy-weapons repulsorlift platoon, company command, and support. Each armor platoon has four heavy or eight light/medium line vehicles, one Chariot, and its HTV support pair. The captain commands from a PX-4 Mobile Command Base rather than another tank. The heavy configuration therefore contains 12 line fighting vehicles, three Chariots, and one PX-4; the light/medium configuration contains 24 line fighting vehicles, three Chariots, and one PX-4. The mechanized heavy-weapons element provides capabilities absent from an armor-only formation.

Breakthrough Armor Company

Combines four armor platoons under a PX-4 Mobile Command Base. The heavy configuration contains 16 line fighting vehicles and four Chariots; the light/medium configuration contains 32 line fighting vehicles and four Chariots. Unlike the Attack Armor Company, it does not replace an armor platoon with mechanized heavy-weapons troops. Its company-level support element is held at battalion headquarters, although each platoon retains its organic HTV pair. It is intended for concentrated armored action followed by relief, replenishment, or support from more balanced forces.

Artillery Battery

Four artillery lines give 16 medium/heavy pieces or 32 light pieces. The battery includes command and support in addition to its firing elements. Fire control, resupply, movement, and local protection remain essential even when individual lines are assigned to support other formations.

Drop Company

A line-company establishment with expanded support and preparation for deployment from orbit. Environmental preparation, landing arrangements, communications, and resupply are planned for the destination. It is not automatically a special-missions company simply because it arrives by landing craft.

Scout Troop

Four scout platoons provide 116 personnel in subordinate formations, including 40 mounted scouts, before company command and support are added. Its mixed infantry and reconnaissance establishment must not be described as 116 speeder-bike scouts. Headquarters and support require their own transport.

Special Missions Company

Three special-missions platoons and a 22-person all-mounted scout platoon provide 136 personnel; company command and support bring the standard total to 164. The scout element contains four five-person lances plus its lieutenant and sergeant major. Support may be positioned separately for a short mission, but remains part of the unit's accountability.

Battalion

A major commands the battalion through a headquarters coordinating intelligence, logistics, medical services, technical work, and headquarters security. A standard headquarters establishment is 90 personnel, including its security element. Specialist battalions may require larger or mobile headquarters. Headquarters security is not additional line infantry unless explicitly reassigned.

Line Battalion

Three line companies and one assault company, plus headquarters. With baseline companies, the total is 810 personnel: 608 in the subordinate platoons, 112 in company command/support, and 90 at battalion headquarters. Expanded assault-company weapon teams can raise the total to 828. The battalion is not simply four copies of an eight-person-squad multiplier.

Assault Battalion

One line company, two assault companies, and a repulsorlift company, plus headquarters. It brings concentrated infantry firepower and a mobile component to attacks on defended objectives. Its strength depends on the weapon-team and transport establishments actually assigned.

Repulsorlift Battalion

Three repulsorlift companies and a scout troop with mobile headquarters. It is suited to reconnaissance in force, exploitation, screening, and rapid movement across dispersed objectives. Its crews, infantry, and scout elements retain distinct tasks.

Armor Battalion

One Breakthrough Armor Company, two Attack Armor Companies, and one Repulsorlift Company, with an enlarged mobile headquarters and maintenance establishment. Conventional heavy and light configurations contain 53 or 93 tanks respectively. This is a combined-arms organization, not four identical tank companies; its infantry component remains important for holding terrain and protecting vehicles.

Artillery Battalion

Three batteries with an assault company for protection and battalion headquarters. The firing establishment provides 48 medium/heavy pieces or 96 light pieces. Batteries may support separate formations without becoming simultaneously available for a second full-strength battalion fire mission.

Special Missions Battalion

Four special-missions companies plus headquarters give a baseline of 746 personnel and 88 scout bikes. Headquarters must support dispersed specialist teams and provide continuity when individual detachments are operating separately.

Regiment

A lieutenant colonel normally commands a regiment of four battalions with a regimental headquarters. The headquarters coordinates support, replacement, repair, and employment across its battalions. Numerical strength follows the actual battalion mix, not a universal 2,000-person figure.

Line Regiment

Two line battalions, one assault battalion, and one repulsorlift battalion. It balances a sustained infantry presence with mobile and heavier-firepower elements that can be concentrated without committing every subordinate unit.

Assault Regiment

Two assault battalions, one line battalion, and one armor battalion. It concentrates forces for deliberate attacks on defended objectives while retaining infantry and armored support. Occupation and prolonged area security may require reinforcement or relief by other formations.

Repulsorlift Regiment

Three repulsorlift battalions and one armor battalion. It emphasizes dispersed movement, exploitation, and rapid concentration, supported by a mobile headquarters. Mobility does not remove the need for fuel, maintenance, recovery, and secure supply routes.

Armor Regiment

Two armor battalions and two repulsorlift battalions. This balanced armored establishment combines tank strength with mechanized forces. It is normally employed within a larger combined-arms operation rather than presumed sufficient to occupy extensive terrain alone.

Vanguard Armor Regiment

Three armor battalions and one repulsorlift battalion. It concentrates more tank formations and less mechanized infantry than the standard Armor Regiment. That difference changes its support and holding requirements; Vanguard is not merely an honorary label for an otherwise identical regiment.

Artillery Regiment

Concentrates multiple artillery battalions under regimental fire-control and support arrangements. Its establishment explicitly lists protective and mobile elements. Batteries and battalions can be allocated to supported commands as required; retaining regimental administration does not require every weapon to fire as a single mass.

CompForce Formations

CompForce Assault is COMPNOR's armed paramilitary reserve, organized into standardized formations under commissioned CompForce officers. Its units defend essential installations, protect relief operations, reinforce Imperial forces, and conduct stabilization duties requiring trained military force. Personnel receive instruction in weapons, small-unit tactics, communications, and first aid, with readiness assessed before military deployment.

When attached to an Army formation, CompForce units provide additional manpower for security, reinforcement, and combat operations under the receiving command's operational orders. They retain their CompForce identity and administration, with support and liaison arrangements established for the deployment.

Battlegroup

A high colonel commands a battlegroup, normally built around four regiments with headquarters and supporting elements. It is a major combined-arms formation. Its troop strength and total personnel must be calculated from its actual composition.

Line Battlegroup

Provides a sustained infantry-centered presence with mobile and supporting elements. Its role is broader than a single concentrated armored thrust, and its attached capabilities must be specified rather than presumed.

Reinforced Battlegroup

Also termed an assault battlegroup, it provides a stronger mix of combat capabilities for demanding operations. Its established regiment mix distinguishes it from a line battlegroup receiving a temporary extra unit; both permanent composition and temporary attachments are recorded.

Armored Battlegroup

Concentrates armor for successive attacks against defended concentrations. Maintenance, resupply, reconnaissance, and supporting infantry are essential parts of its employment, not incidental additions to a tank total.

Mobile Battlegroup

Emphasizes mechanized movement and rapid response across dispersed objectives. It is distinct from an armored battlegroup: maneuver and transport capacity, as well as tank firepower, determine its effectiveness.

Auxiliary Allocation

The auxiliary battlegroup designation describes a pool of supporting or attached resources rather than another interchangeable maneuver battlegroup. Actual command and support arrangements are specified for each allocated element. CompForce and externally supplied air support retain their service identities; the allocation does not create an additional duplicate force.

Corps

A major general commands a corps, normally coordinating four maneuver battlegroups together with headquarters and allocated support. Auxiliary resources are listed separately from those four formations. The corps headquarters directs operational priorities, intelligence, sustainment, and reinforcement.

Line Corps

Provides a general-purpose mixture of forces for sustained surface operations. Its capabilities depend on its actual subordinate establishments and support, not an assumption that no specialist equipment is needed.

Atrisian Corps

An assault-oriented corps designation, distinguished by its operational emphasis and assigned formations rather than a blanket claim that every soldier is superior to those in other corps. Its detailed establishment governs the strength available for concentrated offensive action.

Armor Corps

Concentrates armored formations and their supporting forces for heavy combat. Compared with a mobile corps, its establishment emphasizes armored striking power rather than treating speed and firepower as interchangeable qualities.

Mobile Corps

Emphasizes maneuver across a broad operational area, using mobile formations to concentrate or shift forces rapidly. Its transport, maintenance, and route requirements are explicit parts of the plan.

Army

A general commands a field army, normally combining four corps. A balanced establishment may include line, Atrisian, armor, and mobile corps. Actual totals include the army headquarters and all assigned support, and change with attachments and readiness. The title does not guarantee that a force can conquer or hold an entire star system.

Systems Army

A high general commands the Systems Army, primarily an administrative and coordination headquarters for its assigned field armies. It normally oversees one to three armies, with additional formations assigned as required. It coordinates reinforcement and access to supporting forces without personally directing every subordinate engagement.

Sector Army

A surface marshal commands the Sector Army, coordinating surface forces across a sector. It normally oversees two to four Systems Armies. Its strength is the sum of its actual subordinate commands and support, not a fixed sector-wide troop allowance.

Numbered Army

The twenty Numbered Armies are the Army's Oversector commands, retaining their historical identities from the earlier Sector Army organization. They are distinct from locally designated field armies such as a numbered army associated with a particular world or system. They range from the 1st Army headquartered at Anaxes to the 20th Army headquartered at Tallaan.

Attachments, support, and succession

Permanent establishment, temporary operational control, and support available on request are recorded separately. A tank platoon attached to infantry remains an accountable tank platoon. An artillery battery supporting several units cannot be counted at full availability in each. Requests for naval, Starfighter Corps, or siege support identify the responsible service and the supported command.

Transport plans count crews before passengers. Maintenance and medical support, ammunition, supply vehicles, and droids remain visible in returns even when they do not accompany the forward fighting element. A support element positioned at higher headquarters is not considered nonexistent.

Each command has a designated successor. Loss of an officer changes command responsibility without creating a new formation or eliminating its surviving personnel. Officers may participate directly in combat, but their position and responsibilities remain part of the existing establishment.
