The Tired Army: Exhaustion, Recovery and the Human Limits of Ukraine’s War
By Matthew Parish
Saturday 24 October 2026
There is a peculiar mythology surrounding armies at war. Soldiers are imagined as reservoirs of courage from which a state may draw indefinitely. They may be frightened, wounded or killed, but somehow they are not supposed to become tired. Military communiqués speak of resilience, morale, combat effectiveness and rotation. They seldom use the simpler vocabulary heard among soldiers themselves: I have had enough; I cannot sleep; I cannot think; I no longer care; I want to go home.
Ukraine is now deep enough into its war with Russia for this distinction to matter enormously. The full-scale invasion began in February 2022, but many Ukrainian servicemen had already accumulated military experience during the preceding eight years of fighting in the Donbas. By late 2026, the Ukrainian Armed Forces are confronting something historically familiar but institutionally difficult to acknowledge: an army can remain courageous while becoming profoundly tired. Indeed, courage and exhaustion are perfectly capable of coexisting in the same person.
This is not merely a psychological problem. It is a strategic one. Ukraine’s shortage of combat-ready personnel has made adequate rotation increasingly difficult, and recent reporting describes soldiers remaining at or near the front for extraordinary periods because replacements simply do not exist in sufficient numbers. Analysts have also connected exhaustion, poor organisation, uncertain service duration and inadequate training with unauthorised absence and desertion. The problem is therefore better understood as a system of mutually reinforcing pressures than as evidence that Ukrainian society has suddenly lost the will to resist.
That distinction is essential because a tired soldier is not necessarily a demoralised soldier, and a demoralised soldier is not necessarily a coward. The human nervous system has limits, and no quantity of patriotic exhortation can abolish them.
The physiology of endless war
Combat exhaustion is sometimes discussed as though it were principally an attitude of mind. It is nothing of the sort, because the body participates in war just as surely as the intellect does.
A soldier exposed repeatedly to artillery, drones, explosions, death, interrupted sleep and the anticipation of sudden violence inhabits an environment in which the ordinary mechanisms of human stress are continually activated. Hypervigilance, which is extremely useful when an FPV drone may appear without warning, becomes destructive when maintained indefinitely. Sleep becomes shallow. Concentration deteriorates. Irritability increases. Memory becomes unreliable. Emotional responses may flatten. Decisions that would once have been obvious become difficult.
Eventually something more curious can happen. Fear itself may diminish, not because the soldier has become braver but because he has become exhausted. The nervous system cannot remain indefinitely at maximum alarm, and what looks from outside like extraordinary composure may sometimes be something closer to emotional depletion.
This condition is particularly dangerous because the resulting soldier may continue functioning. He walks, talks, cleans his weapon and performs his duties, yet his judgment may have deteriorated. He may become reckless about risks that once frightened him. Small frustrations can provoke disproportionate anger. He may cease maintaining equipment carefully or become indifferent to his own safety. The exhausted soldier can therefore appear outwardly competent while his margin for error is progressively disappearing.
The phenomenon is hardly unique to Ukraine. Every industrial war has rediscovered it under different terminology. What was once called shell shock, battle fatigue or combat exhaustion has subsequently been divided among more precise psychiatric and physiological categories. Yet military organisations repeatedly rediscover the same underlying fact: human beings cannot be exposed indefinitely to mortal danger without consequences.
The contemporary Ukrainian battlefield adds peculiar burdens of its own. Drones have enlarged the psychological geography of danger. Places that might once have constituted a recognisable rear can now be observed or attacked. Movement itself can be hazardous, and the distinction between being “in combat” and “away from combat” consequently becomes less clean. General Oleksandr Syrskyi has acknowledged that drone dominance has transformed the concepts of front line, rear and depth and made logistics and battlefield movement substantially more difficult.
Rest measured merely in kilometres from the front may therefore not be rest at all. A soldier who has moved twenty kilometres backwards but remains within the reach of drones, missiles and alerts has changed his geographical position without necessarily leaving the psychological battlefield.
The problem of infinity
There is another form of exhaustion that has little to do with sleep. It is the exhaustion produced by uncertainty, and in a prolonged war it can become almost as corrosive as physical danger itself.
A person can endure astonishing hardship when he knows when it will end. Ten days can be survived. Six months can be counted. Even a year can be marked upon a calendar. Indefinite service is psychologically different because there is no number against which suffering can be measured.
For much of the war this has been one of the most corrosive features of Ukrainian military service. A mobilised serviceman might know why he was fighting and remain utterly committed to Ukrainian independence while nevertheless having no reliable answer to a very elementary question: when will I be allowed to stop? That question should not be mistaken for cowardice.
A forty-year-old man may simultaneously believe that Russia must be defeated, love his country, wish to protect his children and desperately want to see those children again. Human beings routinely hold several truths at once, whereas military propaganda has an unfortunate tendency to permit them only one.
Ukraine has begun addressing precisely this problem. The Ministry of Defence’s 2026 reforms introduced contracts with defined periods of service and guaranteed periods outside military service afterwards. The underlying principle is one of predictability: those who undertake longer or more hazardous service should nevertheless be able to see some horizon beyond it.
This may prove psychologically almost as important as increased pay. Money compensates hardship, whereas a date on a calendar limits it, and human beings endure finite hardship differently from hardship that appears potentially endless.
Rotation is a psychological treatment
The most effective treatment for excessive combat exposure is not necessarily psychotherapy. Sometimes it is removing the soldier from combat, allowing him to sleep and placing him somewhere in which nobody is trying to kill him.
This sounds almost embarrassingly obvious, yet armies under manpower pressure have powerful incentives to obscure it. When there are insufficient replacements, resilience programmes become institutionally attractive because they promise to make the existing soldier endure more. Meditation, counselling, psychoeducation and breathing exercises are considerably easier to provide than another trained infantry battalion. They have their place, but no psychological technique abolishes biology.
Ukraine took an important step in April 2026 when Syrskyi ordered that personnel at forward combat positions should ordinarily remain there for no more than two months, followed by mandatory rotation within the following month. The order also required medical examinations and rest after combat tasks. The significance of such an order goes beyond personnel administration because it recognises that rotation is itself a medical and psychological intervention.
The difficulty is implementation. A commander cannot rotate a battalion with imaginary soldiers. If formations are understrength, every man withdrawn from the line creates another problem somewhere else. Ukraine consequently faces a vicious circle: manpower shortages prevent rotation; inadequate rotation produces exhaustion; exhaustion encourages absence and desertion; these reduce manpower further; and the soldiers remaining must carry still greater burdens.
Breaking that circle requires more than recruiting additional people. It requires using existing people intelligently and abandoning the assumption that the maximum immediate utilisation of every available soldier necessarily produces the maximum long-term military effectiveness.
Psychology close to the soldier
Ukraine has nevertheless developed increasingly sophisticated psychological machinery during the war. This matters because military psychology is most useful before a serviceman has suffered a complete psychiatric collapse, rather than afterwards when the damage may be much harder to reverse.
The Ministry of Defence’s mental-health programme for 2025–2030 envisages a unified support system, greater staffing by qualified military psychologists, training of military doctors, new psychotherapist and clinical-psychologist positions, suicide-prevention measures, peer-support training and methods for identifying psychological disorders earlier. Subsequent reforms have permitted civilian psychologists to participate directly in support for servicemen and formalised interventions including crisis assistance, counselling, decompression, peer support and psycho-education. They have also placed responsibility upon commanders to recognise signs of psychological maladaptation and obtain timely assistance.
This is broadly the correct direction because soldiers frequently do not present themselves to psychiatrists saying that they have developed a psychiatric disorder. They complain instead that they cannot sleep. They drink. They become angry. They quarrel with commanders or spouses. They stop speaking. They take unnecessary risks. They become physically exhausted by tasks they previously performed easily.
Hence the value of peer support. A fellow soldier may notice deterioration before a clinician ever sees it, precisely because he knows how the person behaved before something began to change. Ukraine’s emerging system accordingly begins with self-help and peer-to-peer support, proceeds through psychological personnel within units, and escalates towards specialist treatment where necessary. NATO-supported programmes operating in Ukraine have likewise concentrated upon combat stress, psychological recovery and restoring unit readiness.
There is also a specifically Ukrainian intervention known as Combat Path Debriefing, developed to help personnel process combat experience and restore readiness before returning to operations. Its designers situate it within the broader tradition of combat and operational stress control rather than treating every normal reaction to extreme circumstances as psychiatric illness.
That distinction is important. Grief after watching friends die is not insanity. Sleeplessness after months beneath drones is not evidence of defective character. Fear after nearly being killed is not a psychiatric aberration. The danger of over-medicalising combat exhaustion is that medicine can inadvertently be asked to make tolerable circumstances that ought instead to be changed.
Sometimes the correct prescription is sleep, while sometimes it is three weeks at home. Sometimes it is transfer to another duty, and sometimes it is simply the knowledge that one’s service has an end. The sophisticated military institution must be capable of distinguishing between these possibilities rather than prescribing resilience indiscriminately.
Administration as mental healthcare
This leads to a less fashionable proposition: some of the most important psychological reforms of the Ukrainian Armed Forces have nothing obviously psychological about them. A competent personnel office can occasionally do more for morale than a psychologist because many forms of military misery are administrative before they become psychiatric.
Soldiers become exhausted not only from Russian artillery but from pointless bureaucracy, arbitrary decisions, incompetent superiors, inexplicable transfers, delayed leave, uncertainty about pay and the sensation that nobody within the institution knows or cares what happens to them. Military organisations inevitably restrict individual autonomy, but they need not eliminate it altogether.
Ukraine’s Army+ system is therefore psychologically interesting. Electronic applications have increasingly replaced layers of paper bureaucracy for matters including leave and transfers. By late 2025 more than a million electronic reports had been submitted through the system, with annual leave, health matters and changes of duty station among the most common requests. The 2026 reforms have gone further by permitting qualifying personnel to obtain certain transfers within a corps through a more automatic process and by creating clearer routes for personnel absent without leave to return to service in a new unit.
These reforms restore a small quantity of agency, and agency matters enormously to exhausted people. One of the most psychologically destructive features of prolonged military service is the sensation that nothing one does affects one’s circumstances. If a serviceman knows that he can apply for leave, change an unsuitable unit, appeal an administrative decision, obtain treatment and eventually leave military service under comprehensible rules, then the army becomes an institution in which he participates rather than a machine inside which he is trapped.
That difference cannot readily be measured on a spreadsheet, but it can determine whether a person continues serving. Administrative reform is therefore not ancillary to morale; in a prolonged war it may be one of its foundations.
Ukraine also provides annual main leave under martial law, subject inevitably to operational restrictions, and qualifying combat veterans may receive additional leave. The challenge, as ever, lies not merely in creating rights on paper but ensuring that units possess sufficient personnel to honour them. A theoretical holiday does not cure exhaustion, because a right that can never in practice be exercised may ultimately intensify rather than alleviate frustration.
The commander as medicine or disease
There is another uncomfortable subject. Soldiers do not experience “the Armed Forces of Ukraine” as an abstraction; they experience their commander, their sergeant, their company and the handful of people with whom they share danger every day.
A good commander can make terrible conditions tolerable, while a bad commander can make tolerable conditions unbearable. Military leadership under prolonged warfare therefore becomes partly an exercise in conservation of human beings.
Commanders must know which soldiers are reaching their limits, distribute dangerous duties intelligently, prevent unnecessary exposure, permit rest where circumstances allow, suppress bullying and petty humiliation, listen to experienced non-commissioned officers and distinguish temporary psychological deterioration from indiscipline. Above all, commanders must resist the temptation to regard human beings as interchangeable entries on a staffing table.
This becomes harder as casualties accumulate. New soldiers arrive, old friendships disappear and units lose institutional memory. Commanders themselves become exhausted, so the officer deciding whether a soldier needs rest may not have slept properly for weeks either. Psychological support must consequently extend upwards as well as downwards.
The right to become tired
Perhaps the greatest psychological change required is cultural. Ukraine has understandably celebrated its soldiers as heroes, and heroism was indispensable in 2022, when the survival of the state was uncertain and extraordinary numbers of ordinary citizens performed extraordinary things. But heroism has a dangerous secondary effect: heroes are not supposed to complain.
Real soldiers do complain, because real soldiers are human beings rather than figures in patriotic sculpture. They become frightened, bored, furious, lonely and tired. They miss their wives and husbands. They worry that their children are growing up without them. They resent civilians drinking coffee in Kyiv or Lviv while they sit in mud. They may simultaneously understand perfectly well that civilian life is precisely what they are fighting to preserve.
None of these feelings constitutes betrayal. A mature military culture permits soldiers to say that they are exhausted before exhaustion expresses itself through alcoholism, violence, desertion, psychological collapse or suicide. It makes seeking help evidence of professional self-maintenance rather than weakness, and it teaches soldiers elementary techniques of emotional regulation and peer support while also teaching commanders that psychological resilience is a finite operational resource.
This is why the incorporation of psychological-resilience training into basic military preparation represents an important conceptual shift. Mental preparation becomes part of soldiering in the same way as first aid or marksmanship. Yet resilience must never become a euphemism for infinite endurance, because the purpose of resilience should be to preserve human beings through hardship rather than to provide an administrative justification for imposing unlimited hardship upon them.
An army must preserve what it spends
The Ukrainian Armed Forces have achieved something extraordinary. They have sustained resistance against a larger state through years of industrial warfare while simultaneously transforming doctrine, technology, organisation and training. Yet the very duration of that achievement creates its next danger, because Ukraine cannot manufacture experienced soldiers as it manufactures drones.
A serviceman who has survived two or three years of warfare possesses knowledge that cannot quickly be taught. He recognises sounds, patterns and dangers instinctively. He understands when a position is becoming untenable. He knows what inexperienced soldiers do when frightened. He has learned the peculiar ecology of the modern battlefield.
Allowing such a person to become psychologically destroyed through avoidable exhaustion is therefore not merely cruel; it is militarily wasteful. Ukraine’s demographic and strategic circumstances make the conservation of experienced personnel especially important because the country cannot assume an unlimited supply of replacements.
The future Ukrainian military must consequently think increasingly in terms of human sustainability. Frontline exposure must be measured and limited wherever operationally possible. Rotation must be planned before units reach collapse. Leave must become predictable. Personnel should have greater control over transfers and career paths. Psychological support must exist close to units and enjoy confidentiality. Commanders must be evaluated partly by how effectively they preserve their personnel rather than merely by whether they hold terrain.
Soldiers displaying early symptoms of combat exhaustion should likewise be treated before those symptoms become disabling, and families must be incorporated into the recovery process. Perhaps most importantly, military service must possess comprehensible horizons. None of this is sentimental; it is the arithmetic of a long war.
Russia possesses a much larger population. Ukraine cannot afford a personnel philosophy founded upon the proposition that exhausted soldiers can simply be replaced by other exhausted soldiers. Its comparative advantage must lie partly in treating trained servicemen as scarce human capital whose experience should be preserved.
There is an old military temptation to imagine morale as something commanders insert into soldiers by speeches, flags and exhortations. In reality morale emerges substantially from trust: trust that the man beside you will remain at his position; trust that your commander will not waste your life unnecessarily; trust that ammunition will arrive; trust that if you are wounded somebody will come for you; trust that if you begin to fall apart somebody will notice; and trust that the state for which you are fighting remembers that you remain a human being.
Ukraine’s developing system of rotations, defined service periods, psychological support, peer intervention, leave, administrative digitalisation and greater personnel choice suggests that this lesson is gradually being institutionalised. The reforms remain constrained by the brutal mathematics of manpower and by a war whose operational requirements cannot always accommodate humane administrative ideals, but the direction is important.
The ultimate purpose of military psychology should not be to teach a man how to endure indefinitely what no human being can endure indefinitely. It should be to recognise the limits of endurance early enough that courage is not consumed unnecessarily. Ukraine needs soldiers who can continue fighting, and to achieve that it must also permit them, periodically and without shame, to stop.
The strongest army is therefore not the army that never becomes tired, because no such army has ever existed. It is the army that recognises exhaustion without confusing it with cowardice, preserves its people before they are broken, and knows what to do when they become tired.
