The traditional brigade support area (BSA) consolidates the light support battalion (LSB) staff, distribution, maintenance, and medical companies, along with key nodes such as landing zones, maintenance collection points, and ammunition transfer points. When aggregated, the BSA spans several kilometers, creating a significant physical and electromagnetic signature. This concentration reduces survivability, limits rapid displacement, and places the brigade’s bulk sustainment capabilities at risk from a single precision strike.
As the Army transitions toward large-scale combat operations (LSCO), infantry brigade combat teams are transforming into mobile brigade combat teams (MBCTs), designed to increase operational tempo and collapse the kill chain through rapid maneuver enabled by Infantry Squad Vehicles. Sustainment formations must evolve accordingly, developing the ability to project support forward at comparable speed. This transformation aligns with the Army’s Transformation in Contact and broader doctrine, organization, training, materiel, leadership and education, personnel, and facilities modernization efforts.
Unique to the MBCT is the reduction of brigade-level enablers, with engineers and fires returning to division control and the deactivation of the cavalry squadron. As a result, the LSB assumes an expanded role, sustaining newly integrated formations such as the Multi-Function Reconnaissance Company (MFRC) and, in the 101st Airborne Division’s case, enabling air assault operations supporting joint forcible entry. These changes place sustainment at the center of operational reach and continuity.
Cluster Concept Development
The initial sustainment design explored a three-cluster model, with two forward clusters focused on agility and a rear cluster housing heavier, less mobile assets. Ultimately, the 526th LSB adopted a two-cluster concept to simplify command and control while retaining redundancy and survivability. This design preserved the intent of dispersion while enabling flexibility to shift assets rapidly in response to maneuver requirements.
The rear cluster (Blue) was responsible for receiving bulk resupply from the combat sustainment support battalion (CSSB), breaking down commodities, and preparing pre-configured loads. The forward cluster (White) received these loads and executed rapid distribution to combat logistics companies (CLCs), largely through container roll-in/roll-out platform exchanges. This construct allowed continuous sustainment during displacement, with one cluster operating while the other maneuvered.
One key deviation from the initial design was the decision for Role 2 medical operations to function independently from both clusters. While doctrine provides a framework for disaggregated BSAs, the execution revealed that sustainment flows are heavily influenced by Soldier-level processes and relationships across echelons.
Execution of the Cluster Concept — CbR 26-01
Each cluster integrated elements from all LSB companies to provide distribution, maintenance, medical support, and staff oversight in a single location. Asset and personnel allocation was deliberate, enabling sustainment over extended ground lines of communication while mitigating detection from enemy Unmanned Aerial Systems (UAS) and indirect fire. Large tactical vehicles were concealed within tree lines and camouflaged to reduce signature.
The Blue cluster operated under the Bravo Maintenance Company command team, while the White cluster was controlled by the Alpha Distribution Company command team. Although Bravo Company did not formally transition to a maintenance supply company for the rotation, it operated in that capacity for Combined Resolve (CbR) 26-01, integrating supply, maintenance, and distribution functions to support the rear sustainment node. Similarly, Alpha Company unofficially functioned as a headquarters distribution company for the duration of the rotation. Each cluster command team exercised full command and control over sustainment operations, base defense, and synchronization, functioning as the sustainment hub for their respective areas.
A critical enabling capability was the employment of small tactical UAS. Although not authorized on the modified table of organization and equipment (MTOE), each cluster leveraged a Skydio drone to provide real-time aerial reconnaissance, detect enemy movement, and inform dispersion and survivability measures.
Blue Cluster
The Blue cluster was distinguished by the presence of battalion-level leadership and staff. The battalion tactical operations center housed the battalion commander, command sergeant major, executive officer (XO), and primary staff sections. The support operations (SPO) section integrated commodity experts, enabling efficient coordination with the White cluster and subordinate units.
Key sustainment leaders included strategic support area leadership, distribution platoon leadership, fuel and water NCOICs, maintenance control personnel, and medical support teams. The cluster maintained robust distribution and maintenance capability, including load handling systems, fuel systems, Hippo water assets, forklifts, and recovery vehicles.
The distribution company received all classes of supply from the CSSB, maintained the authorized stockage list, and prepared pre-configured loads for forward distribution. The maintenance company operated the unit maintenance collection point, provided longer-term repairs, and employed 3D printing to fabricate parts. Maintenance elements also assumed responsibility for base defense, ensuring uninterrupted logistics package (LOGPAC) operations.
The Blue cluster served as the backbone of sustainment and command, providing continuity, survivability, and centralized oversight for the battalion’s sustainment enterprise.
White Cluster
The White cluster functioned as the forward sustainment node, executing distribution, maintenance, recovery, and medical operations closer to the fight. Half of the SPO section operated from White, managing the sustainment synchronization matrix (SYNCMAT) and coordinating directly with CLCs.
Staff enablers included S-2 intelligence support for route planning and displacement, S-6 communications support, and repurposed headquarters distribution company culinary specialists for casualty evacuation and mortuary affairs support. Distribution assets enabled rapid breakdown and redistribution of preconfigured loads, while maintenance teams provided recovery and limited forward repair capability. Medical assets established a casualty collection point to stabilize casualties.
Attached enablers included military police for security and convoy escort, human intelligence teams for detainee operations, chemical reconnaissance for decontamination, and MFRC leadership elements to enable proactive sustainment using organic transportation.
Operating closer to the forward line of own troops (FLOT), the White cluster extended sustainment reach while prioritizing flexibility, protection, and responsiveness under contested conditions.
Distribution Operations
One of the most significant advantages of the cluster concept was its flexibility to distribution operations. The CSSB sustained the Blue cluster while also being able to distribute directly to the White cluster without it being considered throughput distribution. This capability proved especially critical during cluster displacement, ensuring a continuous flow of supplies despite large-scale movements across the battlefield. Both the Blue and White clusters also demonstrated the ability to execute unit distribution when CLCs were unable to do so. The Blue cluster supported artillery units operating further from the FLOT, while the White cluster pushed supplies forward to combat trains command posts in support of maneuvering infantry units. Simultaneously, CLCs were able to leverage the clusters as supply points, enabling responsive and decentralized resupply operations. By introducing built-in redundancy and multiple distribution pathways, the cluster concept broke from the limitations of traditional BSA-based logistics. This approach allowed the supply chain to remain active and adaptable in response to rapidly shifting operational requirements across the battlefield.
ITN: Employment, Delineation, and Modernization
Effective command and control within a dispersed cluster-based sustainment construct depends on the deliberate employment and delineation of communications platforms across echelons. During CbR 26-01, the 526th LSB employed a layered communications architecture that balanced available Integrated Tactical Network (ITN) capabilities with the operational realities of extended distances, frequent displacement, and simultaneous convoy operations.
The primary means of communications within the convoys, per the internal primary, alternate, contingency, and emergency (PACE) plan, was the AN/PRC-163 handheld radio operating on tactical scalable mobile ad-hoc network (TSM) waveform. Each cluster maintained roughly 10 163s dedicated to convoy operations, and the remaining 163s were dedicated to base defense. While this allocation was sufficient for routine convoys, it proved inadequate during emplacements or displacements when all vehicles within a cluster were maneuvering simultaneously.
For convoy commanders, primary communication with the cluster command post (CP) was via the Android Tactical Assault Kit using MiFi pucks for network connectivity. MiFi was selected over the TSM waveform, because TSM’s effective range was insufficient for the convoy’s typical operating distances. The limited availability of MiFi pucks, typically only two to three per cluster, created a single-point constraint. Since one MiFi puck was kept at the CP, only a single convoy could maintain communications at any given time when multiple convoys were typically operating. The alternate system, the Mounted Mission Command, was also unreliable because higher echelons were focused on monitoring other forms of PACE, further restricting command and control during dispersed operations.
Proper delineation and emplacement of ITN platforms enabled the clusters to sustain operations under contested conditions, while misalignment or overextension of those assets directly increased operational risk.
Sustainment Key Leaders — Roles and Responsibilities
LSB Commander
The dispersed sustainment construct fundamentally alters how the LSB commander exercises command and control while advising the brigade commander. Continuous communication with cluster commanders and daily synchronization meetings are essential to maintaining alignment with brigade intent and maneuver plans. The commander articulates sustainment intent, establishes distribution triggers, and coordinates with maneuver battalion commanders to mitigate friction and deconflict terrain.
Brigade XO
As the principal integrator, the XO synchronizes maneuver and sustainment operations. The XO translates the commander’s intent into actionable sustainment guidance and ensures information flow between sustainment nodes.
Brigade S-4
The S-4 develops and maintains the sustainment common operating picture, analyzing logistics status (LOGSTAT) data and communicating requirements to the SPO. This linkage enables responsive, data-driven sustainment planning and informs LOGPAC development and synchronization.
SPO
SPO serves as the central hub for sustainment planning and execution, transforming LOGSTAT data into synchronized sustainment operations. Within the cluster construct, SPO develops LOGPACs, manages the SYNCMAT, and integrates CSSB resupply into brigade timelines through deliberate coordination with both clusters.
LSB Staff
The LSB staff bridges planning and execution, maintaining oversight of sustainment movements and enabling informed decision making. Integration between the S-3 and SPO is essential to align current and future operations within a disaggregated framework.
Cluster Commanders
The role of the cluster commander is critical and not formally defined in Army doctrine, making the deliberate establishment of authorities and responsibilities essential to sustainment synchronization and operational continuity.
Internally, cluster commanders oversaw base defense, force protection, and infrastructure management through deliberate engagement area development and continuous security assessments. Externally, they executed sustainment operations including LOGPACs, recovery missions, aerial resupply coordination, and emergency resupply.
Cluster commanders were empowered to make timely decisions to preserve force protection and mission continuity, including adjusting security postures, employing UAS to enhance situational awareness, and repositioning or displacing clusters as required. They also validated and refined SPO-generated missions, ensuring feasibility, resourcing, and alignment with cluster capabilities. Continuous bottom-up feedback to the brigade XO, brigade S-4, and SPO maintained synchronization between clusters and ensured sustainment plans remained grounded in real-time operations.
Given the operational importance of this role, cluster commanders must be afforded the autonomy and authority to execute decentralized decision making in dynamic and contested environments.
Lessons Learned and Recommendations
Sustainment Meetings and Systems
A single daily logistics synchronization proved insufficient. The implementation of daily SYNCMAT validation meetings improved alignment but lacked deliberate LOGSTAT integration. A two-meeting structure is recommended:
- LOGSTAT refinement meeting between battalion S-4s and brigade S-4.
- SYNCMAT mission meeting led by the SPO to finalize missions.
Internal cluster syncs and comprehensive personnel and equipment trackers enabled effective command and control and informed decision making.
SYNCMAT
The SYNCMAT is the brigade’s primary sustainment fighting product. Developed collaboratively, it aligns sustainment with maneuver by sequencing resupply from CSSB to Blue, Blue to White, and White to CLCs. Maneuver drives sustainment, and early integration is essential.
Information Flow Between Clusters
Formalized cluster-to-cluster updates are required to ensure shared understanding. Recurring, short-duration battle update briefs between cluster commanders and SPO planners improved synchronization and reduced friction.
UAS as a Sustainment Enabler
One of the most valuable enablers of the cluster-based sustainment construct during CbR 26-01 was the employment of small tactical UAS within sustainment formations. Although not formally authorized on the LSB MTOE, the integration of UAS at the cluster level significantly enhanced situational awareness, force protection, and decision making across dispersed sustainment nodes.
UAS employment enabled cluster commanders to monitor terrain surrounding sustainment nodes, detect enemy movement, and assess routes prior to convoy departure. This capability proved especially valuable during periods of limited visibility and heightened threat, allowing commanders to make informed decisions regarding convoy timing, route selection, and asset dispersion. In several instances, UAS provided early warning that enabled clusters to adjust security postures or reposition assets, directly contributing to survivability and mission continuity.
The exercise reinforced that sustainment formations operating in a dispersed environment face many of the same reconnaissance and protection challenges as maneuver units. Thus, UAS must be viewed as a core sustainment enabler. When integrated with cluster command and control processes, UAS improved responsiveness, reduced reaction time to emerging threats, and enhanced the commander’s ability to balance risk across multiple simultaneous operations.
Future implementations of the cluster concept must formally incorporate UAS into sustainment formations through MTOE authorization, training, and doctrine. Providing organic UAS capability to LSBs would institutionalize the benefits observed during CbR 26-01.
Conclusion
The 526th LSB’s execution of cluster-based sustainment during CbR 26-01 demonstrated that sustainment can be as agile and survivable as the maneuver force. Disaggregated clusters enhanced operational reach, maintained tempo, and reduced vulnerability in a contested environment.
Key lessons underscored the importance of deliberate synchronization, disciplined information flow, empowered cluster commanders, and technological modernization. Agile sustainment requires decentralized execution paired with centralized oversight, enabled by shared understanding and robust communications.
The cluster-based model provides a scalable framework for MBCT sustainment in LSCO. These lessons represent a foundation for the continued evolution of the Army’s tactical sustainment structure, ensuring sustainers remain active contributors to maintaining combat power and operational momentum in future conflicts.
