Table of organization and equipment
Table of organization and equipment
from Wikipedia

A table of organization and equipment (TOE or TO&E) is an originally U.S. Army term for the specified organization, staffing, and equipment of military units. The British Army often used the term "establishment," including the War Establishment, after mobilization.[1] Also used in acronyms as 'T/O' and 'T/E'. It also provides information on the mission and capabilities of a unit as well as the unit's current status.

The term was created when the War Department was preparing the Tables of Organisation and Tables of Equipment for 1943. In the process the two types of organisation documents were merged, creating TOEs.[2]

A general TOE is applicable to a type of unit (for instance, an infantry battalion) rather than a specific unit (the 2nd Battalion, 4th Infantry Regiment). Sometimes, all units of the same branch (such as Infantry) follow the same structural guidelines; much more often, there are a wide variety of TOEs to suit specific circumstances (Modified Tables of Organization and Equipment (MTOEs), in the United States Army, for example).

Soviet Union and Russia

[edit]
FM100-2-3 - The Soviet Army, Troops, Organization, and Equipment; this document contains a number of simplified Tables of Organization and Equipment

In the Soviet and the Russian Armed Forces the term used for TO&E since the 1930s is "Shtatnoe raspisanie" (Штатное расписание [3] literally translated as Shtat Prescription). It originates from the term "Shtat" (ru:штат) which literally means "assignment" and in a secondary meaning as the synonym for TO&E itself. Note that in the Soviet Union and modern day Russia the term "Shtatnoe raspisanie" applied not only to military unit, but also to state organizations such as ministries, agencies, universities, hospitals etc. and even to the corporate structure of private companies.

Many of the Red Army's rifle divisions at the beginning of Operation Barbarossa were operating on Shtat 04/400 of 5 April 1941.[4] This Shtat stipulated that an infantry division should consist of three infantry regiments, a light and a howitzer artillery regiment, other artillery units, a reconnaissance battalion, a combat engineer battalion, signals, chemical company (decontamination/flamethrower), transport, medical, and logistics train units, an aviation flight, and a division staff seemingly consisting of the division commander (1/0/0), division staff (70, including 12 horses and 13 vehicles), a quartermaster section of five officers (5/0/0), a military tribunal (military justice) of two officers, and a political section of 11 officers.

Soviet rifle divisions were often forced to operate at far below their authorised strengths. For example, in the middle of the fighting on the Eastern Front, on July 20, 1942, a report on the 284th Rifle Division lamented:[5]

In the division there are 3,172 military servicemen; a batch of replacements numbering 1,312 men has arrived and another 2,000... are expected, but in the division there are only a total of 1,921 rifles, 98 [semi-]automatic rifles and 202 PPSh submachine guns... There are 21 motorized vehicles in the division, but according to the shtat there should be 114. There are just 7 heavy machine guns, but according to the shtat 108 are necessary. 47 light machine guns, but according to the shtat there should be 350. 36 anti-tank rifles, but 277 according to the shtat. The division's separation from its supply base extends up to 100 kilometres and aggravates the supply [of] food.

The commissar, Tkachenko, went on to urgently request vehicles (including ambulances, of which there were none), small arms and support weapons, draught horses, and a closer supply base. After the first day of fighting he further reported that the lack of high-explosive shells forced the artillery to fire armor-piercing rounds at enemy firing points and troops; there were no cartridges for the submachine guns; many of the men's uniforms and footwear were worn out; and it was impossible to commit the replacements into the fighting because of the lack of weapons.

The actual personnel (field ration) strength of Red Army units and formations during the first 30 months of the Second World War seldom if ever met the specified shtat totals.[6] Manpower shortages were routine if not endemic. When Operation Barbarossa began, the average strength of divisions facing the Germans was about 67%; with enormous variations, the average totals began to rise before offensives as Stavka refilled the divisions in advance of operations, and then formations were ground down in battle. Several instances of divisions continuing to operate with only hundreds of men are recorded. On main attack axes in mid-1943, average personnel strengths reached 75-80% of the required shtat.[7]

After the Second World War, formations were held at a series of descending levels of strength, ("A," "Б," "В," "Г,") corresponding to the first four letters of the Russian Cyrillic alphabet.[8] The reason for the creation of reduced-strength (cadre) units and formations in the USSR Armed Forces was the need to reduce the Armed Forces while simultaneously maintaining officer personnel, stocks of military equipment, weapons and materiel.[9]

For example, in the 191st Motor Rifle Regiment of the "framed" (reduced-strength) 201st Motor Rifle Division at the beginning of December 1979, there were 12 (twelve) people (the regiment was held at a state “G” strength).[10] In connection with the deployment of the regiment to Afghanistan, in January 1980, the regiment's personnel were quickly increased to 2,200 people.

Army

[edit]

In the U.S. Army, there are four basic types of TOEs:

  • The Base Table of Organization and Equipment (BTOE)
    • An organizational design document based on current doctrine and available equipment. It shows the basics of a unit's structure and their wartime requirements (both for personnel and equipment).
  • The Objective Table of Organization and Equipment (OTOE)
    • An updated form of the BTOE, usually formed within the last year. It is a fully modern document and is up to date with current policies and initiatives.
  • A Modified Table of Organization and Equipment (MTOE)
    • A document that modifies a BTOE in regard to a specific unit. Used when a unit's needs are substantially different from the BTOE.
  • A Table of Distribution and Allowances (TDA)
    • A type of temporary TOE that is applicable to a specific mission. Used in an instance when there is no applicable TOE.

Each TOE has a unique number that identifies it. When changes are needed, a table is not modified, instead, a new table is drafted from scratch.

A table of organization (T/O) for the Pentomic Infantry Division as of 1 February 1960. It does not include equipment.

An example of an overall T/O change can be seen when the "Pentomic" organization was superseded by the Reorganization Objective Army Division (ROAD). During the 1950s, the Pentomic reorganization shifted the basic tactical unit from the regiment to the five-company battle group. Instead of brigades, an armored division had three Combat Commands designated: CCA, CCB, and CCC.

On 16 December 1960, the Army Chief of Staff directed a reappraisal of division organization. Resulting studies were carried out between January and April 1961, and fully implemented by 1965.[2] The resulting Reorganization of Army Divisions (ROAD) changed all division types (Mechanized, Airborne, Armor, Infantry and Cavalry) to an identical structure of three brigades of three (sometimes four) battalions. The ROAD division consisted of a mix of nine to twelve armour and infantry battalions based on its Mission, the likely Enemy, the Terrain/weather, and other forces available or Troops (METT). Each brigade would be assigned or attached the mix of battalions and companies based on the division commanders estimate based on METT. As operations continued, the division commander could task organize subordinate units as needed by the flow of the battle.

ROAD was superseded by the Army of Excellence Reorganization of the 1980s.

Marine Corps

[edit]

United States Marine Corps T/O&Es are based on a generic template for each specific type and size of unit, for example, a weapons company of an infantry battalion, or a heavy helicopter squadron. These templates are then modified as needed by the individual unit. The Marine Corps also relies on other documents to report what personnel and equipment a unit actually possesses.

The T/O section denotes every authorized billet within a unit by rank and Military Occupational Specialty required to fulfill the necessary duties. The T/E section denotes authorized equipment by Line Item Number and quantity.

A table of organization and equipment (TOE) is a term originally developed for the military, primarily the and Marine Corps, as a standardized document or system used to prescribe the authorized personnel strength, , mission requirements, and equipment allocations for deployable combat, , and units. Developed as a blueprint for wartime operational needs, the TOE ensures uniformity across similar units by balancing manpower, resources, and capabilities to meet doctrinal standards, while also serving as a baseline for assessing unit readiness and establishing an equipment database. In the , it forms the foundation for modified tables of organization and (MTOE), which adapt the TOE to specific regional, , or mission constraints for individual units, whereas tables of distribution and allowances (TDA) apply to nondeployable institutional support like centers or . The Marine Corps similarly publishes periodic TOE updates to align unit structures with evolving fiscal and operational priorities, often through change requests that refine personnel and equipment offsets. Historically rooted in War Department practices, the TOE system has evolved to support force design and transformation, distinguishing operational warfighting elements from fixed support functions. While TOE refers specifically to the U.S. system, analogous standardized tables of and are employed by other nations' militaries.

Fundamentals

Definition and Purpose

The Table of Organization and Equipment (TO&E), also known as , is a formal document that prescribes the , personnel requirements, and authorized for units to fulfill their designated missions. It specifies the number of positions, ranks, and duties for personnel, along with the of subunits, ensuring a standardized framework for unit composition. Additionally, it details mission-essential , including weapons, vehicles, and support matériel, tailored to the unit's operational role. The primary purpose of the TO&E is to promote operational readiness and efficiency by providing a doctrinal blueprint for unit design, which supports consistent , deployment, and across forces. It balances manpower needs with equipment authorizations based on mission demands, enabling commanders to assess and sustain operations in wartime scenarios. By standardizing like units and measuring full operational requirements, the TO&E facilitates budgeting, planning, and the evaluation of unit preparedness against established benchmarks. Originating in U.S. military practice, the term "Table of Organization" first appeared in the early to formalize unit structures, evolving from ad hoc designs prevalent before into a combined document with equipment allowances by 1943. This distinguishes TO&E from related concepts like Tables of Distribution and Allowances (TDA), which apply to non-combat or fixed installations rather than deployable combat units. The scope of a TO&E encompasses units at various echelons, from small elements like squads and platoons to larger formations such as companies, battalions, and divisions, but excludes temporary or mission-specific modifications that alter the baseline authorization. For instance, a platoon-level TO&E might outline 30-40 personnel with rifles, machine guns, and a light vehicle, while a division-level document could specify thousands of troops supported by , armor, and assets. This hierarchical approach ensures scalability while maintaining focus on core warfighting capabilities.

Historical Evolution

The concept of standardized military organizational tables emerged in 19th-century European armies as a means to enhance bureaucratic control and administrative efficiency amid growing army sizes and complexities. In , following defeats in the , reforms led by and August von Gneisenau in the early 1800s established a modern general staff system that emphasized precise , personnel allocations, and inventories to ensure rapid and coordinated operations. This Prussian model introduced formalized planning documents akin to early organizational tables, prioritizing merit-based staffing and doctrinal uniformity to transform the army from a rigid, aristocratic force into a professional, adaptable entity. The Prussian General Staff's innovations profoundly influenced global military practices, spreading through alliances, military academies, and advisory missions during the late 19th and early 20th centuries. By the , similar bureaucratic frameworks appeared in other European powers, such as France's état-major and Britain's imperial general staff, which adopted standardized tables for and division compositions to manage colonial garrisons and conscript forces. In non-Western contexts, colonial influences facilitated adoption; for instance, British and French models shaped organizational planning in and , while post-World War I alliances like of Nations military commissions promoted these concepts to emerging nations. In the United States, the table of organization and equipment (TO&E) was formalized during through General Staff reforms between 1917 and 1918, building on Prussian-inspired structures introduced by the 1903 General Staff Act. Pre-war efforts had produced initial tables of (TOs) in the 1905 Field Service Regulations and formalized them in for regiments and higher echelons, but wartime demands for rapid expansion led to comprehensive revisions that integrated staffing, , and tactical roles to support the . These reforms separated tables of organization from equipment allowances until their consolidation into TO&E documents by , enabling efficient mobilization of over 4 million personnel. World War II marked significant expansions of the TO&E system, particularly for mechanized units. In 1942, the U.S. Army adopted a new TO&E for armored divisions, reducing personnel from 14,000 to about 11,000 per division while emphasizing mobility with integrated tank, infantry, and artillery battalions to counter tactics observed in . This restructuring, part of broader doctrinal shifts under General Lesley McNair, prioritized lightweight, flexible formations suitable for global theaters, influencing subsequent Allied adaptations. During the Cold War, TO&Es evolved to incorporate nuclear deterrence strategies in the 1950s, reflecting the shift to atomic battlefields. The U.S. Army's "" division structure, introduced in 1957, reorganized infantry and armored units into five battle groups with reduced manpower (around 13,700 per division) but enhanced nuclear delivery capabilities, such as Honest John rockets and tactical atomic artillery, to counter Soviet massed armor under doctrine. This adaptation emphasized dispersed, resilient formations to survive nuclear strikes while maintaining conventional firepower. Post-1991, following the Soviet Union's dissolution, TO&Es transitioned toward flexible frameworks supporting joint operations, driven by lessons from the and the 1986 Goldwater-Nichols Act's emphasis on interservice integration. U.S. Army structures incorporated modular brigade combat teams by the early 2000s, allowing rapid reconfiguration for multinational coalitions and asymmetric threats, moving away from rigid hierarchies to prioritize adaptability in expeditionary contexts. This evolution extended globally through standardization and alliances, influencing partners like the and emerging powers. Soviet equivalents, known as "shtat" (staffing schedules), first appeared in the Red Army's 1920s reorganizations under and , standardizing rifle divisions and mechanized units post-Civil War to build a professional force from partisan roots. These tables, formalized by 1924, allocated personnel and equipment for deep battle doctrine, emphasizing and rapid offensives, and spread to allied communist states via military aid.

Key Components

Organizational Structure

The organizational structure in a Table of Organization and Equipment (TO&E) outlines the personnel framework, command hierarchy, and positional roles that form the backbone of units, enabling coordinated operations across echelons. This structure emphasizes a , allowing units to scale and adapt while maintaining clear chains of command from individual soldiers to higher formations. , for example, core principles focus on balancing , roles, and support functions to achieve tactical effectiveness, with national variations existing elsewhere. In the US military, units are typically organized into progressive echelons, starting with small tactical elements and building to larger operational commands. The smallest unit, a fire team, consists of 4 personnel led by a (NCO) such as a , responsible for basic maneuvers and direct engagement. A aggregates 2-4 fire teams, totaling 8-13 personnel under a , who directs . combine 3-4 squads, encompassing 20-50 personnel commanded by a , serving as the primary tactical subunit with integrated leadership from the . Companies unite 3-4 , with 100-200 personnel led by a , providing administrative and logistical oversight alongside direction. Battalions integrate 3-5 companies, ranging from 300-1,000 personnel under a , functioning as self-sufficient tactical entities capable of independent operations. Higher echelons include brigades (3,000-5,000 personnel, commanded by a ), divisions (10,000-20,000, ), and (20,000-45,000 or more, ), each adding layers of staff for planning and sustainment.

Note: Table illustrates typical echelons in US Army infantry units; sizes and structures vary by branch, unit type, and nation. This hierarchy promotes modularity, where subunits like platoons can be task-organized and attached to larger formations for specific missions, enhancing scalability without disrupting overall command flow. For instance, a rifle company often maintains 120-150 personnel to balance firepower and mobility, influenced by factors such as mission duration, terrain, and operational tempo. In the US military, personnel specifications are defined by occupational codes, such as Military Occupational Specialties (MOS), assigning roles like infantrymen (e.g., MOS 11B for riflemen and machine gunners), medics (MOS ), or engineers (MOS ) to ensure specialized capabilities within units. Chains of command follow a strict vertical structure: team leaders report to leaders, who report to leaders, escalating to commanders and beyond, with NCOs providing continuity and assuming command if s are unavailable. Typical ratios include 3-4 squads per for balanced and 1 per 20-40 enlisted personnel at the and levels, fostering efficient without overburdening commanders. Support roles, such as radiomen or forward observers, are integrated at levels to facilitate communication and coordination. Standardization principles underpin these structures to promote interoperability, particularly among allied forces, by adopting common echelons and ratios that allow seamless integration during joint operations. For example, the prevalent 3-squad platoon model, augmented by a weapons squad in some armies, ensures predictable scaling and mutual understanding of unit capabilities across nations. This approach minimizes friction in multinational contexts, as seen in frameworks like NATO's doctrinal guidelines, where hierarchical consistency supports combined arms effectiveness.

Equipment Authorization

Equipment authorization within a table of organization and equipment (TO&E) refers to the formal process by which units are assigned specific matériel to fulfill their designated missions, ensuring alignment with operational and resource constraints. In the Army, this process follows a structured framework, such as a multi-phase force development cycle that includes capability assessment, organizational design, model development, authorization determination, and documentation. Criteria for assignment prioritize minimum essential wartime requirements, evaluating the unit's role—such as assigning anti-tank guided missiles to formations for defensive capabilities against armored threats—while considering doctrinal guidelines and mission profiles. Approvals are channeled through higher command authorities, often requiring justification via updates or concept plans to adapt to evolving threats or technologies. Equipment is categorized into distinct types to match unit scale and function, with quantities proportional to organizational size; for instance, like rifles are authorized at the individual level, while heavy weaponry such as pieces is allocated at the battery or level. Common categories encompass end items (e.g., personal weapons, vehicles), support gear (e.g., communications systems, transport vehicles), and ancillary items (e.g., sets, kits, and outfits for specialized tasks). Sustainment items, including tools and protective equipment, are also included, excluding expendables like rations or fuels that fall under separate supply protocols. These authorizations are documented using standardized identifiers, such as line item numbers, to facilitate and tracking across services. Logistical integration ensures sustained operational readiness by incorporating , supply, and replacement provisions directly into the authorization tables. Maintenance requirements specify support , such as diagnostic tools or spare parts floats, managed through centralized commands to maintain equipment availability. Ammunition loads are scaled by role—for example, basic combat loads of 210 rounds per for units—and handled via dedicated class V storage and distribution systems. Replacement cycles are governed by requisition processes and distribution programs, with periodic reviews to identify excess or shortages, promoting pooling of assets in non-deployed units to optimize efficiency. Balancing factors in equipment authorization involve trade-offs among mobility, , and cost to achieve doctrinal objectives without overburdening resources. High-mobility units may prioritize lighter vehicles over heavier armored ones to enhance rapid deployment, while is scaled to threat levels, such as authorizing crew-served weapons for elements. Cost considerations include economic feasibility analyses for commercial alternatives, and is enforced through standards like NATO's Agreements (STANAGs), which promote compatible equipment across allied forces to enable operations. These guidelines ensure authorizations support both national doctrines and multinational frameworks.

National Implementations

United States

The Table of Organization and Equipment (TO&E) in the United States is managed by the Department of Defense, with the U.S. Army's framework outlined in Army Regulation (AR) 220-1, which establishes policies for unit status reporting and force registration based on the Modified Table of Organization and Equipment (MTOE). This regulation uses MTOE as the baseline for assessing personnel fill (P-level), equipment on hand (S-level), equipment serviceability (R-level), and training proficiency (T-level) to determine overall unit readiness (C-level) for missions. Equivalent directives exist for other services, such as the Navy's Table of Organization and Rates (TO&R) and the Air Force's Unit Manning Documents, ensuring standardized force structure across the joint force. The system emphasizes joint operations, as detailed in Army Field Manual (FM) 3-0 (March 2025 edition), which integrates landpower contributions to joint campaigns through scalable, multi-domain formations. The evolution of U.S. TO&E reflects adaptations to post-Vietnam challenges, shifting toward modular structures in the 1980s with the Army of Excellence program, which reorganized divisions into lighter, more flexible brigades to enhance deployability against Soviet threats. This modularity accelerated in the early 2000s under Chief of Staff General , creating self-sufficient Brigade Combat Teams (BCTs) with organic reconnaissance, sustainment, and fires capabilities to support rotations in and via the Army Force Generation (ARFORGEN) model. Current efforts under the 2025 Army Transformation Initiative (ATI) further promote adaptability by converting Infantry BCTs to Mobile BCTs, integrating long-range precision fires and unmanned systems, consolidating commands, and overhauling acquisition structures with six new Portfolio Acquisition Executives (as of November 2025) to streamline force design for contested environments. Cross-service integration occurs through the Universal Joint Task List (UJTL), a standardized library of joint tasks that aligns service-specific TO&Es with Joint Capability Areas for planning, training, and readiness reporting in systems like the Defense Readiness Reporting System (DRRS). A representative example is the Brigade Combat Team (SBCT), comprising approximately 4,500 personnel and over 300 vehicles, designed as a rapidly deployable, medium-weight formation within the modular structure to enable quick response in operations. Unique to reserves, TO&E allows for Tables of Organization and Rates (TO&R) adjustments to account for part-time manning and equipment drawdown, ensuring scalability for mobilization while maintaining core mission essentiality. Overall, the system prioritizes expeditionary capabilities, evolving from historical lessons like the Spanish-American War to support rapid with standardized logistics and agile units.

Russia

The Russian table of organization and equipment (TO&E) system, referred to as shtat (staff) tables, is administered by the Ministry of Defense and governs the personnel, , and armament allocations for military units. This framework inherits much from the Soviet-era TO&E&E (Table of Organization, Equipment, and Armament) model developed in the , which standardized unit compositions to support and combined-arms operations during . Post-Soviet adaptations have emphasized efficiency and mobility while retaining core elements like hierarchical command and heavy reliance on conscripts alongside contract personnel. Significant reforms began with the 2008 military modernization program, initiated after the , which shifted from large divisions to a brigade-based structure to enhance deployability and reduce overhead. This "New Look" reform eliminated most divisions in favor of permanent readiness brigades, streamlining the Ground Forces from approximately 1.2 million personnel in 2008 to a more agile force structure. Further updates following the 2022 invasion of incorporated lessons from the conflict by integrating unmanned aerial systems (UAS), including the establishment of dedicated drone units and swarm tactics within existing TO&E tables to bolster reconnaissance and strike capabilities; as of November 2025, Russia established a dedicated Unmanned Systems Forces branch to advance these integrations. A representative example is the motorized rifle , typically comprising around 4,000 personnel organized into combined-arms battalions that integrate , armor, and support elements for versatile operations. Such a brigade includes a tank battalion equipped with main battle tanks (approximately 31-41 vehicles), motorized rifle battalions using or infantry fighting vehicles (up to 130-150 per brigade), and supporting and air defense units to enable rapid maneuver. Distinctive features of the Russian TO&E include a pronounced emphasis on as the "God of War," with brigades allocating significant resources to and tube batteries—often outnumbering maneuver elements—for superiority in offensive and defensive roles. The system also prioritizes reserve , maintaining large stockpiles of equipment and personnel tables that allow for rapid expansion of units during conflicts, contrasting with the Soviet era's focus on oversized, less mobile divisions by favoring smaller, brigade-level formations since the reforms.

United Kingdom

The employs a structured approach to tables of organization and equipment (TO&E) through Equipment Tables (ETs) and associated schedules, which detail authorized personnel, vehicles, weapons, and support items for units based on their establishment. These are managed under the Defence Framework (DLF), where ETs align with unit manning requirements derived from form AF C8005, ensuring equipment entitlements match operational roles. Manning tables track trained strength against requirements, with supplements for specialist trades like the Royal Electrical and Mechanical Engineers (REME) to maintain equipment. This framework supports interoperability, emphasizing modular designs that allow rapid reconfiguration for operations. Historically, the UK's TO&E evolved from large imperial divisions during , where War Establishment Tables authorized up to 800 personnel per battalion with Bren guns, anti-tank weapons, and universal carriers for mechanized support. Post-war, structures focused on armored brigades, but the 1982 marked a shift to flexible battlegroups, such as 3 Commando Brigade's task-organized units combining , , and for amphibious assault, totaling around 5,000 personnel with light equipment like 81mm mortars and anti-tank missiles to enable rapid sea deployment over 8,000 miles. These ad hoc formations highlighted the need for scalable, expeditionary TO&E beyond rigid divisional models. Under current doctrine, such as Joint Doctrine Publication 0-20 UK Land Power (2023 edition), the adopts an adaptive campaigning approach to address hybrid threats, integrating conventional, irregular, and below-threshold activities like cyber and through multi-domain operations. TO&E emphasizes force types—heavy (e.g., tanks for high-protection roles), medium (Ajax vehicles for balanced mobility), and light ( for rapid insertion)—with whole-force manning drawing from 73,000 regulars and reserves for cohesion and sustainability. Post-Cold adjustments prioritize NATO-aligned scalability, as seen in the , to counter state adversaries blending military and non-military tactics. A representative example is the standard infantry battalion, authorized for approximately 700 personnel organized into a , three companies, and support elements like a mortar , equipped with 1,903 protected mobility vehicles (e.g., ) across the force and anti-tank guided missiles for dismounted operations. commando units, such as , maintain a similar scale of around 800 personnel in a , three close combat companies, and specialist troops (e.g., and anti-tank with six systems each), focused on amphibious assault with Viking all-terrain vehicles and L85A3 for littoral maneuver. These structures balance firepower, protection, and deployability within broader TO&E. Unique to the is the integration of TO&E with partners, facilitating combined operations through shared standards in exercises like those under the Five Power Defence Arrangements, where Australian and elements align with British light scalable forces for . The emphasis on light, scalable designs enables rapid deployment, as demonstrated by the 7th Light Mechanised Brigade's ability to generate a Very High Readiness battalion within days, using air-portable equipment for NATO's eastern flank reinforcement. This approach contrasts with heavier U.S. structures by prioritizing alliance-heavy, expeditionary agility over independent .

Other Nations

The of employs tables of organization and equipment (TO&E) that emphasize large-scale , drawing parallels to Soviet-era shtat structures in their detailed prescription of personnel, units, and assets for operations. A typical PLA group army, serving as a corps-level formation, comprises approximately 45,000 to 60,000 personnel, including multiple brigades, , air defense, and support elements designed for theater-level engagements. These TO&Es prioritize numerical superiority and integrated firepower, with each group army integrating infantry, armor, and to support rapid, high-intensity maneuvers. Major reforms initiated in 2015 under the Central Military Commission restructured the PLA from seven military regions to five joint theater commands—Eastern, Southern, Western, Northern, and Central—to enhance integrated operations across services. This shift decentralized administrative control while centralizing operational authority under theater commanders, allowing TO&Es to adapt more dynamically to scenarios, such as amphibious or border defense missions. The reforms reduced overall PLA strength by 300,000 personnel by 2017, streamlining TO&Es to focus on quality over quantity, with group armies now emphasizing modular brigades equipped for multi-domain threats. In the Israel Defense Forces (IDF), TO&Es are designed for high flexibility to accommodate a conscript-based force, enabling rapid mobilization and adaptation to asymmetric threats through scalable unit configurations. The exemplifies this approach, structured as an infantry formation with five battalions—including three (12th, 13th, and 51st), a unit (Gadsar), and support elements—that incorporate rapid mobilization kits for quick deployment in urban or border operations. These kits include modular equipment loads, such as IWI X95 assault rifles, machine guns, and Spike anti-tank guided missiles, allowing conscripts to transition from training to combat roles within weeks via phased instruction in close-quarters battle and anti-guerrilla tactics. The emphasis on technological asymmetry in IDF TO&Es prioritizes precision weapons and intelligence integration over mass, with brigade-level assets like armored personnel carriers enabling agile responses to threats from non-state actors. The Indian Army's (ORBAT) tables, which function similarly to TO&Es, retain a British colonial legacy in their hierarchical structure, specifying personnel, vehicles, and weaponry for terrain-specific operations. divisions, such as the 3rd or 8th, typically consist of around 15,000 personnel organized into three to five brigades, with a heavy emphasis on regiments equipped for high-altitude warfare, including 155mm howitzers and multi-barrel systems to counter rugged terrains along borders. These ORBATs integrate battalions with engineer and support tailored for sustained operations in regions like the , where mobility is limited, ensuring divisions can operate semi-independently with airlifted supplies and pack-mule transport. Comparative trends in developing nations reveal variations in TO&E adoption, often blending local needs with international standards for . In (AU) peacekeeping forces, such as those under the , equipment tables are standardized to UN norms, focusing on small arms, unarmored vehicles, and non-lethal tools to facilitate rapid deployment in stabilization missions. This approach emphasizes modular kits— including AK-pattern rifles, basic medical supplies, and communication gear—drawn from UN pre-deployment training modules, allowing multinational contingents from nations like or to integrate without heavy burdens. Such adaptations highlight a global shift toward expeditionary, resource-constrained TO&Es that prioritize sustainability over scale.

Variations by Military Branch

Ground Forces

The table of organization and equipment (TO&E) for ground forces emphasizes scalable structures optimized for terrestrial maneuver, direct and indirect fires, and sustained operations across varied terrains. These adaptations prioritize infantry as the core maneuver element, integrated with armored, , and support assets to enable operations. Common across many nations, ground forces TO&Es balance , mobility, and while allowing for mission-specific task organization. Infantry-centric models form the foundational building blocks of ground forces, scaling from to divisions. A representative example is the standard , consisting of 9 personnel organized into two 4-soldier fire teams and a ; each fire team includes a team leader, an automatic rifleman armed with an M249 (SAW), a with an M203 , and a , all primarily equipped with M4 carbines. These aggregate into of approximately 40 soldiers (three plus a weapons squad) and companies of 100-130 soldiers (three to four ), providing flexible maneuver elements for offensive and defensive tasks. variants adapt this structure by incorporating (), such as the , to transport and protect while enabling dismounted assaults; a typically fields four IFVs, each carrying a squad, to enhance mobility and survivability in open terrain. For comparison, use a 9-10 soldier motorized in IFVs, emphasizing heavier anti-tank integration per VDV doctrine. Armored and artillery elements integrate with infantry to deliver decisive firepower and protection. Tank platoons commonly organize into four main battle tanks, such as the , divided into two sections of two vehicles each for mutual support during advances. In battalion-level formations, a typical ratio approaches 1:1 for tanks to infantry companies, as seen in U.S. Army battalions with two tank companies and two companies, ensuring balanced maneuver without over-reliance on any single arm. Artillery integration often includes self-propelled guns, like the M109 Paladin howitzer, organized in batteries of six vehicles per to provide responsive indirect fires; these systems accompany maneuver units to suppress enemy positions and shape the battlefield. Logistics tails underpin ground forces , typically comprising about 20% of divisional personnel dedicated to supply, , and support. These elements include dedicated sustainment battalions with trucks, handlers, and ammunition bearers to maintain operational , often drawing from field manuals that outline equipment authorizations for 72-hour combat loads per . For instance, U.S. in ATP 3-21.8 specifies organic squad-level sustainment like rucksacks with 7 magazines per and 200-400 rounds for the SAW, scalable to divisional levels where support units ensure continuous resupply. Terrain adaptations present key challenges, particularly for airborne units requiring lighter loads to facilitate rapid deployment and extraction. Airborne TO&Es emphasize reduced equipment weights, such as paratrooper-configured M4 rifles and lighter anti-armor systems like the , to limit individual loads to under 100 pounds for jump operations; this contrasts with heavier mechanized setups but enhances agility in austere environments. Such modifications, informed by historical airborne doctrines, prioritize dismounted mobility over vehicular dependence to exploit surprise in restricted terrains. In naval forces, the Table of Organization and Equipment (TO&E) delineates the personnel structure, billets, and matériel allocations for sea-based units, emphasizing operational readiness for extended maritime operations, combat survivability, and integration across surface, subsurface, and amphibious domains. Unlike land-based units, naval TO&E prioritizes afloat hierarchies that account for confined spaces, damage control imperatives, and blue-water , with compositions tailored to vessel types and mission profiles. This framework ensures that ships and embarked forces maintain cohesive command chains while supporting multi-domain warfare, including anti-air, anti-submarine, and strike capabilities. For instance, Type 45 destroyers authorize crews of about 190 personnel, focusing on integrated air defense with fewer billets than U.S. equivalents due to . Shipboard organization under naval TO&E typically structures crews into departments such as , , weapons, and operations, with divisions and work centers handling specialized functions. For example, an Arleigh Burke-class destroyer (Flight IIA) authorizes approximately 329 personnel, comprising 32 officers, 27 chief petty officers, and 270 enlisted sailors, organized to operate advanced missile systems like the combat suite. Carrier air wings, embarked on carriers, involve over 1,800 personnel across nine squadrons, including units equipped with F-35C Lightning II aircraft for multi-role missions, enabling the projection of air power from the sea. These tables specify billets for roles critical to vessel sustainment, such as aviation maintenance and operations, ensuring the air wing's integration with the ship's crew for seamless deployment. Amphibious elements in naval TO&E incorporate Expeditionary Units (MEUs), which consist of about 2,200 and sailors organized as a Marine Air-Ground Task Force (MAGTF) for rapid crisis response. An MEU integrates ground combat elements with naval and amphibious ships, allowing for the seamless transition from sea to shore operations while aligning with broader ground TO&E for and support. This structure supports self-sustained operations for 15 days, including and components that enhance naval expeditionary capabilities. Equipment specifications in naval TO&E focus on sensors, weapons, and sustainment systems optimized for prolonged deployments. Aegis-equipped destroyers, for instance, feature 96 vertical launch system (VLS) cells capable of deploying Standard Missile-2/6 for air defense, land-attack missiles, and vertical launch anti-submarine rockets, complemented by radar for threat detection. Sustainment provisions include fuel, , and repair kits to enable independent operations for months, with redundancies in power generation and water production to counter attrition in contested environments. Doctrinally, the U.S. Navy's OPNAVINST 3120.32D establishes standard billets and organizational requirements for all units, mandating crew tables that balance operational efficiency with safety protocols. A key emphasis is on damage control teams, such as the Damage Control Training Team (DCTT) led by the Damage Control Assistant, which conducts drills in firefighting, flooding mitigation, and chemical, biological, radiological, and nuclear defense to enhance ship survivability. These teams train the entire crew, ensuring universal proficiency in emergency response as per the instruction's guidelines.

Air Forces

In air forces, the table of organization and equipment (TO&E) delineates the personnel, , and support assets required for aerial combat and sustainment units, with a primary emphasis on squadrons as the core operational building blocks. These structures ensure balanced capabilities for air superiority, , and logistical support, integrating pilots, maintenance crews, and specialized roles to maintain generation rates. For instance, organizational hierarchies typically place squadrons under groups within wings, allowing scalable deployment from fixed bases or expeditionary environments. In the Royal Air Force, squadrons similarly field 12-18 with ~250 personnel, adapted for interoperability. Fighter squadrons form the backbone of tactical air power, typically authorized 18 primary aircraft such as F-35A or F-16C models, supported by approximately 300 personnel including 24 pilots and dedicated flightline crews. Bomber groups, often comprising two to three squadrons, integrate heavy platforms like the B-52H Stratofortress with extensive maintenance detachments; a representative such as the maintains three squadrons across its operations and maintenance groups, totaling around 9,000 personnel to service its fleet of B-52s and ensure global strike readiness. These units prioritize robust ground support, with maintenance crews handling phased inspections and weapon system integrations to achieve high mission-capable rates. Support elements extend TO&E to airlift and unmanned systems for versatility in contested airspace. units, exemplified by C-130J squadrons, operate with 8 to 10 and roughly 150 personnel per deployed element, enabling tactical resupply and troop movement in austere conditions. (UAV) detachments, such as those for the MQ-9 Reaper, organize around 12 per squadron, with sensor operators and intelligence analysts comprising the core team to execute persistent surveillance and precision strikes. Equipment allocations in air force TO&E emphasize advanced avionics for beyond-visual-range engagements and standardized munitions loads to optimize sortie effectiveness. Aircraft like fighters are equipped with integrated suites including (AESA) radars and data links for . A representative munitions configuration includes two AIM-120 advanced medium-range air-to-air missiles (AMRAAM) per on platforms such as the F-16, complemented by short-range AIM-9X Sidewinders for close-in defense. Ground support ratios maintain operational tempo, with dedicated maintenance crews to cover pre-flight checks, refueling, and repairs. Operational doctrine shapes air force TO&E through mechanisms like the (ATO), a 24-hour directive issued by the to assign missions, call signs, and sequencing for all aerial assets, ensuring deconfliction and prioritization in joint environments. For rapid deployments, expeditionary wings incorporate kits such as the Air Rapid Response Kit (ARRK), a modular system deployable by 60 personnel in under six hours to establish command-and-control tents and housing for austere operations supporting fighters or bombers. These elements, often scaled to 100-150 airmen per team, facilitate quick setup of air bases in forward areas.

Modern Adaptations

Technological Integration

The integration of digital tools into the planning and development of tables of organization and equipment (TO&E) has transformed how military forces structure units to meet evolving operational demands. In the United States, the Joint Capabilities Integration and Development System (JCIDS) process employs simulation software to model and validate capability requirements, including force structure and equipment allocations, thereby streamlining the identification of gaps in TO&E designs. For instance, discrete-event simulations within JCIDS have been used to assess process efficiencies, such as combining initial and capability development documents to reduce documentation timelines while ensuring robust TO&E evaluations. Additionally, artificial intelligence (AI) applications are emerging to support predictive analytics in military decision-making, enabling faster assessments of unit readiness and resource needs that indirectly inform TO&E adjustments. Cyber and space capabilities have become integral to modern TO&E since the 2010s, reflecting the recognition of information dominance in multi-domain operations. The U.S. Department of Defense has incorporated cyber elements into force structures through the Cyber Mission Force, which includes teams dedicated to offensive, defensive, and support operations, influencing unit-level TO&E by adding specialized personnel for network protection and disruption. Satellite communications (SATCOM) systems have similarly been embedded in unit tables to enhance connectivity, with initiatives like the Defense Science Board’s 2017 task force recommending integrated tactical networking to support resilient, global command and control architectures across services. By the late 2010s, these elements were standardized in TO&E documents to ensure units maintain secure, high-bandwidth links for joint operations, as outlined in U.S. Strategic Command’s management of AEHF and other SATCOM assets. The incorporation of and unmanned systems is reshaping TO&E by augmenting human capabilities and reducing personnel requirements in high-risk roles. In the U.S. Army, reforms in the have prioritized equipping squads with small, expendable drones to enhance and precision strikes, with directives mandating one such system per by 2026 to boost lethality without expanding manpower. This integration, part of broader efforts to field over a million low-cost drones, allows for modular attachments to existing units, thereby optimizing TO&E for hybrid human-machine formations while minimizing exposure to enemy fire. Despite these advancements, integrating technology into TO&E presents challenges in balancing with elements to preserve operational effectiveness. Defense Science Board studies project that by 2030, innovations like AI-driven systems and autonomous platforms will require TO&E adaptations to maintain oversight, addressing risks such as over-reliance on tech that could degrade decision-making in contested environments. prototypes, such as those under the Prototype Resilient Operations Testbed for Expeditionary Urban Scenarios (), demonstrate tools for simulating urban operations that influence future TO&E by testing human-technology interfaces, highlighting the need for training and doctrinal shifts to mitigate integration hurdles. Emerging research further emphasizes adapting military practices to keep pace with these technologies, ensuring that TO&E evolutions prioritize warfighter resilience alongside technical superiority.

Modular and Expeditionary Designs

Modular designs in tables of organization and equipment (TO&E) emphasize interchangeable components that allow units to adapt quickly to diverse missions without extensive restructuring. In the U.S. Army, Brigade Combat Teams (BCTs) exemplify this approach through a plug-and-play structure, where heavy, infantry, or battalions can be swapped to tailor combat power for specific operational environments. This modularity, accelerated in the mid-2000s, enables BCTs to integrate organic enablers like fires, logistics, and intelligence, facilitating rapid deployment and flexibility across conflict spectra. Similarly, NATO's Response Force incorporates modular building blocks in its multinational logistics, using organizational templates that permit the addition, shifting, or deletion of functions to match operational needs, thereby enhancing responsiveness in non-Article 5 scenarios. Expeditionary TO&Es prioritize lightened structures optimized for air and sea lift, reducing logistical footprints while maintaining essential capabilities for initial entry operations. The U.S. Marine Corps' (MEU), a forward-deployed Marine Air-Ground Task Force (MAGTF), typically comprises about 2,200 personnel organized into a command element, reinforced landing team, composite squadron with up to 16 (including MV-22 Ospreys, F/A-18 Hornets, and CH-53E Super Stallions), and a combat logistics for sustainment. As of the 2025 Force Design Update, MEUs are being modernized with advanced systems such as the Navy-Marine Expeditionary Ship Interdiction System (NMESIS) and Marine Air Defense Integrated System (MADIS) to enhance multi-domain capabilities and lethality. This configuration supports crisis response within six hours and sustained operations for 15 days, with task-organized detachments like explosive ordnance disposal sections ensuring scalability from sea-based platforms. Scalability in modern TO&Es relies on task organization around mission-essential tasks, allowing units to expand or contract based on theater demands. Following the 9/11 attacks, the U.S. military shifted from a division-centric model to a -focused structure, enabling independent BCT operations over non-contiguous areas and rapid force tailoring with supporting brigades for sustainment and fires. This evolution supports deployment of a brigade within 96 hours, adapting to stability or high-intensity missions through modular attachments. Globally, the United Kingdom's Littoral Manoeuvre leverages Multi-Role Support Ships (MRSS) for amphibious , with up to six vessels designed to transport , vehicles, aircraft, and insertion craft for flexible littoral operations and rapid force projection starting in the early 2030s. In , Spetsnaz units under the Special Operations Command demonstrate adaptability through independent brigades that deploy small, mission-tailored detachments of 500 or fewer personnel, often combining elements from multiple sources for intelligence, sabotage, or in contested environments.
