In every conflict, someone must keep the force moving, fueled, armed, and able to fight. When that system fails, even the best maneuver plan can collapse.

In March 2003, Soldiers of the 507th Maintenance Company, 5th Battalion, 52d Air Defense Artillery Regiment, 11th Air Defense Artillery Brigade, learned that lesson the hard way near An Nasiriyah, Iraq.

A navigational error, fatigue, and friction across a long convoy left a small maintenance element isolated under heavy fire, resulting in 11 of 33 Soldiers killed and nine captured before U.S. Marine units from Task Force Tarawa rescued the survivors (Peters, 2004).

That convoy showed in brutal detail that sustainment is not a rear-area function, it is combat power, and NCOs often decide if it works when it matters most.

Sustainment only becomes combat power when NCOs treat it as a warfighting function by enforcing standards as combat tasks, anticipating requirements in contested environments, protecting sustainment nodes as critical terrain, and developing data-savvy, competent Soldiers from garrison through multidomain operations (MDO).

Sustainment as Warfighting, Not Rear-Area Support

The sustainment warfighting function consists of systems and tasks that provide support and services to ensure freedom of action, extend operational reach, and prolong endurance (Department of the Army [DA], 2019).

It links national resources to Soldiers at the point of contact. It includes logistics, personnel, and health support services that allow commanders to keep fighting after the first contact and the first mistake.

Army Doctrine Publication (ADP) 4-0, Sustainment (2026), states that commanders cannot maintain tempo or seize and hold the initiative without reliable sustainment that leaders plan, rehearse, and protect across the depth of operations.

In his NCO Journal December 2024 Muddy Boots article, “Sustaining Combat Readiness,” Command Sgt. Maj. Jimmy J. Sellers, Army Materiel Command, explained that sustainment NCOs stand at the forefront when generating readily capable combat formations in the joint strategic support areas and emphasized that excellence in the fundamentals is critical to warfighting readiness (2024). Sustainment effectiveness directly impacts combat readiness, not just back-office efficiency.

Similarly, in his July 2025 Muddy Boots article, “Sustaining the Fight Through MOS Competency,” Command Sgt. Maj. Marco A. Torres, U.S. Army Combined Arms Support Command, wrote that sustainment generates combat power and that technically proficient sustainment NCOs ensure the force remains mobile, resourced, and prepared for battle (2025).

In complex and contested environments, sustainment NCOs do more than manage supplies, they help commanders maintain endurance, tempo, and options under pressure.

Treating sustainment as a warfighting function starts in garrison. Every motor pool Monday, arms room layout, and training meeting is either building combat power or setting conditions for the future.

When NCOs keep status reports accurate, enforce disciplined maintenance, and conduct realistic field exercise supply planning, they are executing operational preparation rather than performing administrative tasks. They are rehearsing how their formations will fight for endurance under fire. If sustainment generates combat power, then NCOs must turn that responsibility into disciplined execution by enforcing standards as combat tasks.

Enforce Standards as Combat Tasks

The 507th Maintenance Company case highlights how small gaps in standards can create strategic-level consequences. It shows how navigational errors, fatigue, limited communications, and personnel friction left the convoy exposed to a determined enemy using ambush tactics with deadly results (Peters, 2004). Those conditions did not appear overnight. They accumulated over time based on the way leaders enforced planning, movement control, and force protection fundamentals.

ADP 4-0 emphasizes that sustainment extends operational reach and prolongs endurance when leaders enforce maintenance, discipline, and training standards consistently (2026).

Sellers contends that the expertise, leadership, and fundamentals mastery demonstrated by sustainment NCOs directly support equipment readiness and units’ overall well-being (2024).

According to Torres, military occupational specialty (MOS)-competent NCOs turn daily sustainment tasks into readiness by keeping vehicles rolling, gear flowing, and Soldiers supplied for the fight (2025).

At the NCO level, enforcing standards as combat tasks means deliberately connecting everyday actions to survival in a convoy or support area. Instead of conducting fake vehicle inspections or half-hearted crew drills, NCOs should ask themselves and their Soldiers, “Is this good enough in a real fight?”

This question reframes maintenance, weapons handling, and convoy rehearsals as warfighting requirements rather than administrative tasks.

Over time, NCOs can build a culture of combat-grade sustainment in which checklists, load plans, inspections, and rehearsals are designed for contact and friction, not convenience. Enforcing standards with discipline and consistency builds a foundation for NCOs to anticipate sustainment requirements before the first fragmentary order (FRAGO) forces reactive action.

Anticipate Requirements Before the First FRAGO

Anticipation is a core sustainment principle that allows operations to run seamlessly. ADP 4-0 defines it as the ability to foresee operational requirements and initiate actions that satisfy a response without waiting for orders (2026).

In practice, anticipation is how sustainers prevent the organization from pausing a combined arms breach or defense because fuel, ammunition, or critical repair parts arrived a day late. In large-scale combat operations (LSCO), sustainment planners must anticipate demand in environments where adversaries can disrupt ports, strategic lift, and intra-theater distribution at scale (Wilson, 2024).

In his article, “Adapting to the Expected LSCO Conflicts in the 21st Century,” published in the Spring 2024 issue of Army Sustainment, Maj. Thaddeus Wilson used the ongoing Russia-Ukraine war to illustrate how LSCO exposes weaknesses in logistics. Modern adversaries can bring long-range fires and deep strikes against sustainment nodes while forcing both sides to adapt distribution, stockpiles, and repair capacity under heavy attrition (Wilson, 2024).

That environment puts a premium on leaders who think several moves ahead about what their formation will need and what the enemy will likely disrupt. In this context, sustainment NCOs cannot afford to be reactive. They must help staffs anticipate consumption spikes, maneuver-driven demands, and the impact of contested lines of communication.

Tactically, NCOs can build anticipation into their formations. Platoon sergeants can require that every training meeting answer three sustainment questions: What will we run out of first, how will we know, and what is our backup plan?

Maintenance leaders can track patterns in deadline rates and recurring faults across weapon systems to order high-failure parts before the next operation, gunnery, or rotation. Distribution NCOs can use historical fuel and ammunition data from recent field problems to challenge optimistic consumption estimates.

These small anticipatory habits help ensure that when operations accelerate or routes shift, units have redundancy and resilience built into their sustainment plans.

If anticipation prevents operational pauses before contact, protection ensures sustainment can endure once contact begins, which requires NCOs to treat sustainment nodes as critical terrain rather than rear-area afterthoughts.

Protect Sustainment Nodes as Critical Terrain

Sustainment nodes are high-value targets. Ammunition supply points, refuel-on-the-move sites, maintenance collection points, casualty collection points, and convoys offer opportunities for adversaries to create significant effects with relatively small attacks.

In contested logistics environments, adversaries deliberately work across domains to deny, disrupt, destroy, or defeat logistics operations, facilities, and networks (King, 2024). In such environments, sustainment formations cannot assume their lines of communication or support areas are safe. They must expect adversaries to observe, target, and attack in the physical, digital, and information spaces.

In his article, “Contested Logistics Environment Defined,” published in the Winter 2024 issue of Army Sustainment, Maj. Jon M. King wrote that contested logistics include threats to infrastructure, distribution routes, and the data systems that command sustainment, from ports and railheads to forward supply nodes and convoys (2024).

This means sustainment units must be prepared not only to move and supply but also to fight for their own survival and for the endurance of supported forces.

It also means NCOs cannot treat fuel points, supply support activities (SSAs), or maintenance yards as static, rear-area locations. Instead, they must treat these sites as critical terrain whose loss would directly reduce the organization’s ability to fight tactically and strategically.

NCOs protect sustainment nodes by integrating survivability, force protection, and discipline into daily routines.

In garrison, that means designing sustainment field training exercises where SSAs, fuel, or maintenance collection points are designated enemy objectives leaders must plan to defend, camouflage, and displace under notional fire.

When deployed, it means enforcing dispersion, cover, and concealment, and guarding standards with the same seriousness applied to an infantry battle position.

NCOs can also lead simple red-team drills during rehearsals, asking Soldiers how they would attack their own sustainment site if they were the enemy and then adjusting layouts, guard plans, and reporting procedures based on their answers.

Protecting sustainment nodes as critical terrain preserves combat power in the present fight, but sustaining advantage over time requires NCOs to develop data-savvy, competent Soldiers who can integrate technology, analysis, and fieldcraft in contested environments.

Develop Data-Savvy, Competent Sustainment Soldiers

Future sustainment operations will be data-rich and time-compressed. Sellers highlighted that the Army Sustainment Enterprise employs robust logistics information systems that provide real-time equipment visibility and support predictive maintenance to keep formations ready (2024).

He argued that maintaining combat readiness demands integrating civilian education, MOS-specific technical skills, strong leadership, and combined arms proficiency (2024).

Torres reinforced this point, stressing that MOS-competent sustainment NCOs must command advanced systems, automation, and predictive technologies while leading effectively in field conditions as hands-on leaders (2025).

This combination of MOS mastery and data literacy cannot be incidental. NCOs must deliberately develop themselves and their Soldiers to understand both technical systems and the tactics they support.

Torres highlights programs such as training with industry (TWI) and project warrior, which expose sustainment NCOs to commercial logistics practices, advanced tracking systems, and observer-coach roles that strengthen their ability to translate data into actionable decisions (2025). These experiences produce NCOs who can move confidently between the motor pool, the SSA yard, and the main command post.

At the unit levels, platoon sergeants and first sergeants can cultivate data-savvy leaders by integrating real unit data into professional development. They can conduct sustainment-focused tactical-decision exercises that require junior NCOs to brief commanders on maintenance trends, consumption rates, and mission risk if sustainment nodes degrade.

Staff NCOs can coach Soldiers on updating logistics systems, validating reports against ground truth, and articulating sustainment risk clearly during rehearsals. Over time, these repetitions produce NCOs who translate system outputs into decisions that sustain formation endurance, aligning it with the commander’s intent.

Conclusion

NCOs transform sustainment from a support function into decisive combat power by treating it as a warfighting discipline. This combat-focused mindset turns daily garrison routines into conflict rehearsals.

By rigorously enforcing standards, NCOs build the fundamental discipline required to survive under fire. By anticipating requirements, they provide commanders with operational flexibility and prevent pauses in momentum. They protect the force’s endurance when they treat sustainment nodes as critical, defensible terrain.

Finally, they ensure future combat readiness by developing data-savvy and technically proficient Soldiers who can execute these tasks in contested environments. Ultimately, NCO leadership in motor pools, supply support activities, and command posts directly forge resilience and lethality, ensuring the force can not only begin the next fight but win it.
