Ukraine Illustrates How To Win A War Of Attrition

Work around your own weaknesses while exploiting the enemies. This strategy increasingly favors Ukraine as Russia's logistics, battlefield capabilities, troop strength and leadership falter. JL

Lawrence Freedman reports in Comment Is Freed:

Attrition works by persuading enemy forces and their political leadership that their position is untenable and likely to get worse. Ukraine is following a strategy that works round its weaknesses while exploiting those of Russia. Conditions on the ground should increasingly favor Ukraine because of the quality of the systems entering service and the effectiveness with which they are being used. There is something increasingly desperate about Russian rhetoric and behavior. The Russian military is deteriorating and the West’s backing for Ukraine has yet to slacken. The trends favor Ukraine. Putin and his cronies have to work out how long they can continue to pretend they have a credible path to victory.

From the start the course of this war has been charted in two ways. The first is on maps. Progress has been measured by territory acquired; prospects identified by territory in contention; challenges described by territory still to be taken. We will know the war has ended when either Russia has made sufficient gains to satisfy Putin or else Ukraine has taken back Russia’s past gains. The second is by losses. Claims have been made about how many people have been killed and wounded and how much equipment has been destroyed, damaged and abandoned. We will know the war has ended when either Russia or Ukraine has exhausted its capabilities and can no longer continue with the fight. These two measures are related. The consequences of exhaustion are assumed to be most likely felt in the battle for territory. For now, neither measure appears to point to a clear victor. To see where this war is tending, therefore, it is necessary to look beyond both the maps and the lists of losses.

Defence Dominance

But let us start with the maps from the past four months of fighting. What is most striking is how little territory has changed hands. The Russians completed the capture of Mariupol and moved forward with an enormous effort in Luhansk, while Ukraine has been nibbling away at their positions in the Kharkiv and Kherson Oblasts and pushed the Russians off Snake Island. Other than that, not much. So far in this war the defence has been dominant. This could be seen when Russia failed to take Kyiv and then withdrew from northern Ukraine.

But if the defence remains dominant then how can the war end? The Russians remain frustrated that they have not even achieved their minimal objective of taking all the Donbas, while the Ukrainians still have some twenty percent of their country under an increasingly brutal occupation. Even the much-vaunted Ukrainian offensive to retake Kherson appears to be thwarted for the moment because the Russians have moved thousands of troops to boost their defences - in the process making it less likely that their own anticipated offensive in Donetsk will make much headway.

The impression therefore is of a stalemate. In the gloomiest commentary, the two sides are presented as punch-drunk boxers, trading jabs and uppercuts yet unable to land a knockout blow. Because, unlike boxing, there is no referee able to bring the fight to an end and let the judges call a winner, the two appear doomed to keep on punching until one drops from sheer exhaustion. Such commentaries often lead to proposals for the United States to impose a conclusion. To sustain the analogy, Washington might be sitting in Ukraine’s corner but can see the pain being inflicted and is urged to step in and throw in the towel. Otherwise the two are doomed to slug it out until eventually one can fight no more or else, as the logic of the situation is recognised, an uneasy truce is agreed, perhaps a cease-fire that settles nothing but allows the two armies an opportunity to refresh and recuperate before picking up again where they left off.

A war of the sort that we are currently witnessing, with the defence dominant and not much territory changing hands, is one of attrition. Attrition is normally described an alternative type to a war of manoeuvre, which offers the more enticing prospect of a decisive battlefield victory. The only prospect with attrition is of a series of encounters with the cumulative effect of leaving the enemy depleted and exhausted. Generals prefer to think about winning through manoeuvre rather than attrition, through bold offensives rather than stubborn defences. Manoeuvre should be both quicker and less costly, concluding with a clear military victory that creates conditions for a clear political victory. Successful offensives lead to territory being seized and so an outcome imposed; successful attrition requires the enemy giving up.

For understandable reasons therefore attrition is disparaged as an inferior and undesirable form of warfare, requiring patience and an ability to absorb pain, without necessarily offering a plausible route to victory. It is often the result, as in this case, of the aggressor failing to achieve an early victory through manoeuvre. It is chosen largely because it is the only alternative to acknowledging defeat.

But while wars of attrition may open with a stalemate and lack the dash and drama of those of manoeuvre they can still lead to victory. This may be because they create the conditions for a return to manoeuvre warfare or it may be because the losing side recognises that its position can only get worse and needs to find a way out. Moreover there are different ways of fighting an attritional war, and some strategies can be more effective than others.

Attritional Warfare

The word ‘attrition’ derives from a Latin word for rubbing away which came to refer to repressing a vice and an imperfect form of contrition. This led to its original – theological - English meaning as a lesser form of repentance that had a worldly instead of a spiritual motive, lacking the sincerity of true contrition. So from the start it connoted something second-best. It eventually came to refer to a process by which anything from body parts to social conventions might be worn down over time. By the late 19th century attrition was discussed as a military strategy, though it was only during the First World War that it became prominent. After the initial German offensive failed in 1914 the trenches were dug and thereafter both sides struggled to mount successful offensives, taking heavy casualties when they tried. Military thinking after this war concentrated on ways to prevent similar deadlocks in the future, whether through armoured warfare or air power or a combination of the two.

Attrition was therefore established as a form of warfare to avoid, as second best to beating the enemy in a decisive battle. Exhausting an enemy through constant sniping, skirmishing and harassment took time, and increasingly made victory dependent less on the conduct of military operations and more on the underlying economic and social resilience of the nation. In addition, the process worked both ways. One’s own forces also faced attrition, turning war into a contest of endurance.

This view of attrition as an inferior strategy has been a prominent feature of contemporary military thought. Part of the US Army’s own critique of its performance in Vietnam revolved around its reliance on killing as many enemy soldiers as possible so that eventually the communists would be unable to sustain their campaign. This led to a preoccupation with ‘body counts’ as a measure of success, to the point where every Vietnamese killed was assumed to be an enemy combatant, leading to the observation that the Communists had been eliminated many times over.

Those looking for a more intelligent way to fight wars soon identified ‘manoeuvre’ as the superior form. The aim was to rely on speed, surprise and mobility to catch out, disorient and thus defeat the enemy. Generals were encouraged to relearn the art of operations, liberating themselves from dependence on simply throwing firepower at enemy lines. The model was the German blitzkrieg of 1940, although the eventual outcome of that war might have warned of the problem with military breakthroughs that led to incomplete victories and so did not end the fighting.

In practice the manoeuvre/attrition dichotomy can be too sharp. It may well be that commanders have to resort to more attritional methods after failing to secure an early victory, but that does not preclude a later return to a more dynamic approach. Indeed inflicting attrition on your opponent can be a sensible precursor to battle. Instead of rushing an attack, exploiting surprise, it might make more sense to opt for a more methodical approach, taking out enemy capabilities and undermining morale, before embarking on an offensive – what the Americans call ‘preparing the battlefield’.

There is thus a difference between attrition as a way of wearing down an enemy before embarking on an offensive, which might have the additional benefit of persuading the enemy that it is in a hopeless position, and attrition that reflects a situation of stalemate when both sides can resist offensives. In these circumstances, wider economic and social resilience will matter, as both sides try to produce more equipment and ammunition and find more personnel to make up losses. Once one side falters in this effort then they might lose as a result of unrest at home or a progressive inability to fight effectively. The First World War ended because German forces had been weakened due to  the impact of the allied economic blockade as well as constant fighting. In 1918 first they mounted an offensive of their own which they could not sustain and then failed to cope with the counter from the allies.

Attrition and the Russo-Ukraine War

Although the war is going through an attritional stage this does not mean that there is a stalemate. Certainly both sides face the problem of defence dominance: it is hard to dislodge troops who are well dug in and prepared to fight. Large-scale counter-offensives risk exposing concentrated formations in the open to enemy fire. Russia’s recent offensives involved little manoeuvre. Attempts to encircle Ukrainian forces largely failed, except for Mariupol. Instead intensive artillery barrages were used to force Ukrainian defenders to back away. These made possible some small gains at high cost for both sides. This stage of the war is coming to an end. Russia is now struggling to make any significant territorial progress, although it hasn’t stopped trying, while Ukraine aims to seize the initiative so that the fighting is more on its terms. How well it can do so depends on whether it can develop a strategy to fight an attritional war.

Attritional warfare encourages assessments of its progress in terms of comparative losses in both equipment and personnel. With both sides, these assessments are often no more than guesses, especially when it comes to casualties. In practice, much of what we can glean about the extent of their comparative losses comes from their efforts to replace what has been lost. Attrition is not just a question of which side is suffering most but also who is best able to regenerate their combat capabilities. In this respect we can note some of this war’s fundamental asymmetries that continue to shape its conduct:

  • Ukraine is fighting for its sovereignty and territorial integrity and Russia is not. Russia has presented the war as a place to take a stand against both local and distant enemies, including NATO. But it has offered multiple versions of a desirable end state for this war.

  • Russia is a far larger country that has been building up its armed forces. It is clear from current efforts at recruitment that it has suffered extensive losses. It is unlikely to run out of manpower but there are issues of quality, motivation and leadership. Because of its early mobilisation Ukraine has the troops and motivation is high, but because many of its best units have been badly hit it needs to train more before throwing them into a fight for which they are unprepared.

  • Russia has vast stocks of weaponry but it is now having to dig deep into these stocks having used up its more modern equipment. Ukraine lacks the numbers but is now fighting with more modern and effective equipment. In terms of crude firepower - artillery, aircraft and missiles - Russia has the advantage, although not as substantial as the one with which it started. But its ability to wage manoeuvre warfare is now hindered by limitations with its armour and infantry. Ukraine’s capabilities may be improving but they appear to have some way to go. Thus both sides are stuck with attritional strategies for the moment.

  • The war is being fought almost entirely over Ukrainian territory. With a few exceptions close to the border, Ukraine has not attacked targets inside Russia and has actively been discouraged by Washington from doing so.

  • Russia can therefore target vital infrastructure as well as civilian homes inside Ukraine on a regular basis. This has had devastating effects on the Ukrainian economy and everyday life. Ukraine is unable to respond in kind.

  • To cope with this core asymmetry favouring Russia, Ukraine depends on external assistance. Western support is vital both to keeping its economy afloat and also hurting Russia’s economy through sanctions.

  • While Ukraine can produce some of its own war materiel it has also become increasingly dependent on external suppliers for its most effective systems. Russia has few external sources – it is acquiring some drones from Iran – yet its defence production is suffering as a result of sanctions. This is why it is increasingly having to make do with vintage equipment. But Ukraine has been denied systems that can strike Russian territory, notably modern aircraft as well as long-range rockets.

Two conclusions emerge from these asymmetries. First Russia has identified Ukraine’s dependence on external support as its greatest vulnerability and has been looking for ways to undermine this support, largely by aggravating the economic crises facing the West. The debates in the West on whether support for Ukraine will drain away as the economic pain intensifies and ‘war fatigue’ steps in have acquired a routine quality but all one can say is that so far this has not happened. The same is true of direct Russian attacks on the Ukrainian population. The effect has been to reinforce Kyiv’s conviction that it has little choice but to carry on and challenge those, who might argue for a more conciliatory approach to Moscow, to explain why this sort of barbarity should be rewarded.

The second conclusion is that conditions on the ground should increasingly favour Ukraine because of the quality of the systems now entering service and the effectiveness with which they are being used. The Russians are finding new recruits to send to their front (including press-ganging individuals in the occupied territories) but they can no longer be fussy when it comes to their age, education, background, or training. Life at the front for ill-prepared troops is becoming more desperate.

The most striking feature of the fighting since late June has been the demonstrable vulnerability of ammunition dumps, command posts, air defence units and now airfields. The strike against the Saki air base in Crimea was an enormous blow not only to Russian capabilities – with at least nine and possibly as many as 27 aircraft and helicopters destroyed along with airport facilities and ammunition – but also to Russian self-confidence. The Ukrainians are being very coy about how they mounted the attacks, preferring to leave the Russians guessing, (and the guesswork continues on social media). They have said it was not a foreign-supplied system. Was this a one-off operation or a new long-range capability? If the latter then it warns of many ways in which Crimea, Putin’s great gain from 2014, might now be in play. It also serves as a reminder of the curious ineptitude of Russian tactics, constantly underestimating their opponent. The Ukrainians dispersed their aircraft from the start so that they were not caught at their bases.

What we have not seen is Ukraine mounting comparable attacks to those mounted by the Russians in the Donbas in May and June. In this respect defence remains dominant. Ukraine is having to follow a strategy that works round its weaknesses while exploiting those of Russia. This was dubbed back in May as ‘corrosion’ by General Mick Ryan. Ukraine, he noted, has sought to hollow out ‘the Russian physical, moral, and intellectual capacity to fight and win in Ukraine, both on the battlefield, and in the global information environment.’ This is essentially a form of attrition, broadly framed. This strategy has recently been sharpened as Ukraine makes the position of the Russian defenders more parlous, threatening to cut them off completely from their supplies as well as their means of escape, leaving them more exposed to accurate artillery and air strikes. This is the potential risk Russian commanders have accepted by sending extra troops into Kherson. The increased partisan activity from within the occupied territories is tying down Russian troops and adding to their anxiety. Moreover, the spectacular nature of some of the recent strikes eases the need to impress external suppliers by demonstrating the equipment that has been donated is being used to good effect.

There are still reasons for Ukraine to take land. Until territory changes hands and the maps are amended it is hard to convince doubters that the tide of war has turned in Ukraine’s favour. And while the referendums supposedly being prepared in occupied territories to enable residents to vote to be part of Russia will lack both credibility and legitimacy, there are strong humanitarian reasons for seeking to liberate them as soon as possible.

The official Ukrainian line is that the counter-offensive is still on its way. Nonetheless the importance of the damage being inflicted on Russian forces is also being emphasised. In an address on 10 August President Zelensky, using the classic language  of attrition, argued that it was Russian losses that would bring the war to an end:

‘This is a question that worries absolutely everyone: when will the war end? Someone says – months, someone – a year, someone – even more. But the question of time actually directly depends on the question of the losses that Russia will suffer. The more losses the occupiers suffer, the sooner we will be able to liberate our land and guarantee Ukraine’s security. This is what everyone who defends our state and helps Ukraine should think about: how to inflict the greatest possible losses on the occupiers so that the time of the war gets shorter.’

The problem with attrition is that it does not force a decision on the enemy. It works by persuading enemy forces and their political leadership that their position is untenable and likely to get worse. So long as they believe that they are only facing temporary difficulties and can turn the situation around, or at least must show that they have put up a decent fight before folding, then the war will continue. It is easy to understand why Ukraine feels that it has no choice but to carry on fighting and why it is now confident that it is slowly taking the initiative.

Moscow appears to wish to incorporate seized territory into Russia, for which they are preparing some dubious procedures that will impress nobody but themselves. Deep down for Moscow the war may now be all about denying NATO the satisfaction of a Ukrainian victory and saving Putin’s face. There is nonetheless something increasingly desperate about Russian rhetoric and behaviour. The Russian military position is deteriorating and the West’s backing for Ukraine has yet to slacken. The trends therefore favour Ukraine. At some Putin and his cronies will have to work out how long they can continue to pretend that they have a credible path to victory.
