Protection Keeps Maneuver Fighting

Abstract

Operational campaigns lasting weeks or months require armies to keep fighting under constant enemy attack. Ukraine protected its command posts, supply lines, air defense, and maintenance capacity across four years of sustained defense. Armenia lost those same systems within three weeks in 2020. Commanders who estimate protection requirements, plan the shift from breakthrough to sustained operations, and build redundancy into critical systems are far more likely to campaign successfully against capable opponents.

Introduction

Winning a single battle differs fundamentally from sustaining a campaign. A commander concentrating forces for a decisive attack can defeat an enemy in days. An operational campaign lasting weeks or months requires something far more difficult: keeping an army functioning under constant attack from an enemy that can see everything.

Modern reconnaissance transformed the nature of vulnerability. Drones, long-range fires, and electronic warfare made logistical nodes, supply routes, command posts, and assembly areas targetable objectives. A unit that seized ground could culminate because the enemy destroyed supply trucks, jammed radios, disabled command centers, and delayed reinforcements. Armies that lose the systems keeping them alive severely degrade the ability to continue fighting. When those systems fail, soldiers become isolated regardless of their tactical skill.

Two recent conflicts demonstrate why armies should prioritize protection of critical systems. Ukraine preserved enough systems, including command centers, supply routes, air defense, and repair facilities, to sustain fighting across four years despite constant missile strikes and drone attacks. Armenia lost those systems within three weeks in 2020 and its campaign collapsed. Both conflicts show why armies must protect critical systems. Ukraine’s systems survived sustained attack. Armenia’s did not.

Commanders and their staffs should estimate how long the campaign can sustain operations before enemy forces degrade critical systems beyond recovery. If that estimate shows operations will take weeks or months, then protecting those systems should become the requirement that determines whether the army keeps fighting or exhausts its combat power.

Ukraine and Armenia Show the Operational Cost

Ukraine (2022–2026):

By late 2024, Ukrainian leadership formally framed continued defense as a national resilience problem spanning armament, energy, security, communities, and sustained military operations. Kyiv protected and reinforced the systems keeping the war effort functioning across the depth of the battlefield: command and control, ammunition stocks, aircraft, air defenses, maintenance areas, medical support, and movement routes.

Command and control infrastructure was among the opening targets of Russia’s missile and air campaign. The war demonstrated the vulnerability of large, concentrated headquarters to long-range precision fires, reinforcing the need to move command-post locations frequently, disperse key staff functions, and employ deception. Survival of the physical post mattered less than preserving the command function itself. A displaced post without communications does not provide command continuity.

Supply architecture adapted across the campaign. Before the invasion, Ukraine dispersed portions of its ammunition stocks. Russian forces failed to detect significant Ukrainian rail movements during the opening campaign. Rail transport moved forces and materiel across while avoiding some Russian targeting. As Russian reconnaissance improved, Ukrainian logistics shifted to smaller supply nodes, distributed caches, night movement, protected mobility, and short exposure windows. Unmanned systems delivered supplies near the front to reduce exposure of trucks and personnel.

Ukrainian air defense evolved across the campaign. Opening Russian strikes destroyed many stationary sites in the first 48 hours, but mobile systems survived at higher rates. By 2025, Ukraine developed dense networks of passive sensors, electronic-warfare systems, and networked radar guided by interceptor drones. By mid-2026, Ukrainian air defense operated in deep belts of low-cost short-range teams and interceptor drones spread geographically to attrit Russian attack drones before they reached defended targets, with medium- and long-range systems protecting priority assets and critical nodes.

Air defense enabled maneuver. A reserve unit without air protection became a target. An ammunition truck without protected airspace was destroyed. Ukraine dispersed air defense and retained freedom of movement for reserves and logistics. Ukraine aims to protect the entire air-defense system, not just singular air-defense batteries.

Casualty processing and maintenance protection required the same dispersed approach. Before the invasion, Ukrainian Air Force maintenance crews trained to prepare aircraft in field conditions and conduct maintenance and routine repair while aircraft dispersed from main airfields to operational locations. This distributed maintenance capacity contributed to aircraft survival and continued operations. Ground units faced the same problem as Russian reconnaissance: rear areas no longer in sanctuary. Medical nodes, logistics facilities, and recovery sites had to disperse, move frequently, harden, and reduce signatures. Front-line casualty recovery often required hours or days of movement during limited visibility. Units employed fires, obscuration, unmanned systems, and alternate vehicles to protect casualty evacuation teams and recovery sites. Damaged equipment recovery and maintenance became a protection problem because recovery teams and repair sites were targetable.

Brigades fought well tactically, but a larger protected system kept those brigades fighting. Protection extended campaign endurance from weeks into years.

Azerbaijan-Armenia War (2020):

Azerbaijan integrated drones, long-range fires, reconnaissance, and precision strike to attack Armenian systems from the opening day. The campaign shows what happens when those systems degrade under sustained pressure.

Azerbaijan prioritized Armenian air-defense systems, command posts, artillery, and reserves during the opening phase while ground forces began assaults. Azerbaijan targeted air defense, rear-area targets, and close-fight positions simultaneously. Azerbaijan combined unmanned intelligence, surveillance, and reconnaissance with loitering munitions, armed drones, rockets, ballistic missiles, and ground maneuver. Precision strikes reached Armenian assembly areas, command posts, logistics, and maneuver forces approaching the close fight. A missile destroyed a bridge over the Akari River, complicating movement between Armenia and Nagorno-Karabakh.

The sequence was cumulative degradation across interdependent systems, not the loss of one system followed by the next. During the first several days, Armenian fortified positions resisted ground assaults and inflicted losses on Azerbaijani forces. But as the campaign progressed, Armenian tactical competence at close range persisted while protection throughout the depth of the battlefield failed. Armenian losses accumulated across command, supply, ammunition, artillery, and maneuver systems. Forces continued to fight effectively at close range, but reinforcement and resupply were increasingly impaired by precision strikes.

The Lachin-Stepanakert Road was the critical artery linking Armenia with Nagorno-Karabakh. Azerbaijani ground forces cut the road south of Shushi after weeks of attrition and air-defense degradation. Once severed, Armenian forces could not move reinforcements or supplies. The road’s loss coincided with Azerbaijani assault on Shushi and accelerated Armenian operational collapse. Within weeks, Armenian forces still fought effectively at close range, but reinforcement and resupply were increasingly impaired by precision strikes. Protection of a single sustainment line determined whether the army could continue campaigning or collapse under pressure. It collapsed.

Both conflicts reveal an operational lesson through opposite timelines. Ukraine preserved critical supporting systems across years of sustained combat, while Armenian forces experienced rapid degradation of key systems. When armies protect critical systems through dispersion, redundancy, and rapid reconstitution, they sustain operations despite enemy pressure. When armies allow those systems to degrade without replacement, operational collapse follows regardless of tactical skill.

What Protection Means Operationally

Protection in large-scale combat operations comprises three specific functions: dispersion (spreading critical systems so a single strike cannot destroy them), redundancy (maintaining backup systems to replace what the enemy destroys), and hardening (enabling systems to survive enemy fires).

Ukraine pursued all three. Dispersed command centers meant one strike lost a part of, but not the whole, system. Redundant supply lines ensured that other supply lines would keep functioning if one were destroyed. Hardened positions meant reduced casualties and partial functioning if those positions were attacked. Ukraine did not immediately stop operations because it pursued these three functions.

Armenian forces entered the campaign with concentrated command infrastructure, highly constrained sustainment routes, and air-defense systems vulnerable to Azerbaijani reconnaissance and precision strike. Those vulnerabilities accelerated degradation across the force as the campaign continued.

Ukraine built greater resilience and redundancy into critical systems. Armenian forces entered the war with vulnerabilities in air defense, dispersion, and lines of communication that Azerbaijan exploited throughout the 44-day campaign.

Critical Systems and Their Interaction

Operational campaigns depend on protecting five critical systems. The loss of one cascades through all the others. Each of these five systems is protected through dispersion, redundancy, and hardening. Ukraine maintained all five because protecting air defense enabled supply movement, which enabled command post displacement, which enabled maintenance operations, which sustained fighting. Azerbaijan targeted Armenian air defenses at the outset, gained local air superiority within days, then attacked forces and lines of communication. The loss of effective air defense exposed Armenian reserves, reinforcements, and supplies to continued attack. One system failing created vulnerability in all others.

The first critical system is command and control. Higher echelon units cannot fight without lower echelon units, but lower echelon units can fight without higher headquarters. A brigade can fight without a division headquarters. A corps cannot fight without brigade headquarters. A corps losing command posts, especially the ability to move and communicate those posts while under fire, loses the ability to sequence brigades and coordinate operations. Armies lose campaigns when the system coordinating army action disappears. Ukraine kept command posts functioning by dispersing them across the country. Armenia lost that capacity within weeks.

The second: supply lines. Armies advance only as far as supply lines can sustain them. A corps can seize terrain 200 kilometers away but cannot hold it if it cannot continue to supply the forces there. Armenia could not protect trucks, depots, and the routes carrying fuel, ammunition, and water. Without protected logistics, brigades could not sustain operations. Ukraine protected its logistics through dispersion, alternate routes, and other measures that helped sustain operational reach under continued attack.

Third, air defense. In transparent battlefields where drones see everything, air defense determines what can move and what cannot. A reserve unit attempting to move without air defense becomes a target. Armenia lost air defense and lost the freedom to move reserves or supplies. Ukraine dispersed air defense and retained freedom of movement. Air defense is protection that enables maneuver.

Fourth, maintenance and casualty processing. A damaged brigade loses combat strength even if soldiers survive the engagement. Vehicles need maintenance, soldiers need medical attention, and weapons need their ammunition replenished. Brigades require protected space to repair equipment and reintegrate replacements without interference from enemy fires. Ukraine protected those areas. Armenia could not. Without protected reconstitution, brigades cannot regenerate combat power.

Fifth, movement routes and crossing sites. Congestion at crossing sites and routes carrying traffic from multiple brigades creates vulnerabilities. Armenia lost the ability to protect movement routes and river crossings. Forces attempting movement became targets. Ukraine protected those routes and retained flexibility in maneuvering. Protecting routes enables maneuver.

Command, supply, air defense, reconstitution, and movement routes form the infrastructure needed to sustain a campaign. Armies protecting those systems are far more likely to campaign successfully. Armies losing those systems are far more likely to collapse regardless of tactical victories.

How Protection Changes as Campaigns Evolve

Understanding the shift from initial assault to sustained operations illuminates the necessary cognitive shift.

Phase One—Initial Assault (Weeks One and Two): Breakthrough is the critical moment of any campaign. Protection concentrates around breach sites, crossing points, and assault formations. Engineers and assault headquarters need protection. The objective is clear: break through enemy defenses and create operational maneuver room. During the initial assault, brigades accept losses because operational opportunity justifies the cost.

Phase Two—Sustained Operations (Week Three Onward): Once breakthrough succeeds, a campaign enters a different challenge: sustaining operations across the depth of the battlefield while the enemy attacks everywhere. Protection shifts from concentrating around assault formations to distributing across supply lines, movement corridors, reserve areas, and command posts. The objective changes from breakthrough to endurance.

Commanders maintaining Phase One protection priorities into Phase Two are likely to lose the campaign because supply lines become vulnerable, reserves cannot move, command posts cannot displace, and maintenance areas become targets. Armies often stop advancing because the system supporting the advance fails.

The Critical Transition Problem

Shifting from Phase One to Phase Two requires deliberate effort. An army that does not plan transition discovers it has optimized protection for the wrong phase when the campaign shifts. Concentrated protection around breach sites leaves supply lines exposed once breakthrough succeeds. Armies focused on assault protection will suddenly discover that the protection architecture no longer fits the problem. Commanders should understand the transition before the campaign begins. Rehearsals are required before executing the shift under fire. A headquarters that waits to reorganize protection until brigades are moving can lose coherence. The support system changes while operations continue. Transition from Phase One to Phase Two protection is just as difficult as the breakthrough itself.

What Commanders and Staffs Should Address

Commanders and staffs should address four concerns before planning an operational campaign against a capable opponent.

First: Identify the critical systems the campaign depends on, not terrain objectives or enemy formations alone. A logistics hub can matter more than a town 20 kilometers forward because logistics can determine whether the army advances or stops. A maintenance area can matter more than a patch of terrain because maintenance determines whether brigades regenerate. Commanders should identify critical systems before assuming terrain seizure.

Second: Determine the protection requirement for each system. A logistics corridor may require air defense, route security, redundancy, repair capacity, and alternate distribution methods. A supply chain may need enough depth to absorb disruption without stopping the advance. A command post may need to move often enough to survive but remain concentrated enough to coordinate the force. These requirements determine whether the campaign can sustain operations or will collapse under pressure.

Third: Plan the protection priority shift as the campaign moves from assault to sustained operations. Week three protection differs from week one protection. Planning the transition from concentrated to distributed protection, and rehearsing that shift, are required. Armies that plan transitions keep protection aligned with the campaign phase before units enter sustained contact.

Fourth: Estimate how long critical systems can survive enemy attack. Ukraine’s systems lasted four years. Armenia’s lasted weeks. Commanders and their staffs should estimate the timelines where their systems can no longer survive and aim to achieve campaign objectives before systems fail. If they cannot achieve those campaign objectives before the systems break, the plan most likely will fail.

Commanders cannot predict campaign duration with certainty. The enemy determines speed as much as friendly forces do, and sound planning must account for both rapid collapse and extended operations rather than betting on one outcome.

Building Protection Across Duration Uncertainty

Building protection architecture that functions across duration uncertainty is an efficient approach that matches operational reality. Such architecture can sustain dispersed operations whether the campaign lasts two weeks or two years. Redundancy survives extended pressure. Capacity needs to remain to shift protection from assault to sustained operations and adjust again as conditions change.

This approach costs more initial time and positioning than betting on rapid breakthrough. But it means an army can continue fighting across weeks or months. Ukraine developed a more dispersed and redundant system able to absorb sustained attack. Armenian forces entered the war with more concentrated, vulnerable systems and limited redundancy. Ukraine’s campaign lasts into its fifth year. Armenia’s ended in three weeks.

Conclusion

The choice is between building a system that can sustain an operational campaign and betting on rapid victory. Against capable opponents in large-scale combat operations, betting that the enemy will collapse after breakthrough creates risk the force may not be built to absorb.

Commanders and staffs should estimate protection requirements matching their campaign concept, resource those requirements, train the force to execute protection under pressure, and build enough redundancy that the system survives through an extended enemy attack. Protection becomes the decisive factor determining whether an army can campaign successfully or if it will run out of the ability to continue fighting.
