The ongoing conflict in Ukraine has prompted questions regarding the effectiveness of Western-supplied weapons. Despite the assertion that these systems are technologically superior to their Russian counterparts, a decisive victory for Ukraine has not yet materialized. This report aims to provide a comprehensive analysis of the multifaceted reasons behind this situation, moving beyond a simplistic comparison of weapon quality to explore the complex interplay of quantitative disparities, training and tactical adaptation challenges, logistical burdens, Russia's evolving military doctrine and countermeasures, the influence of strategic goals, and the critical role of non-material factors.

The assumption that superior technology automatically translates to battlefield victory is a common oversimplification in the analysis of armed conflicts. History offers numerous examples where technologically advanced forces have failed to achieve their objectives against adversaries employing less sophisticated weaponry but leveraging other advantages such as terrain familiarity, asymmetric tactics, or strong national will. The conflicts in Vietnam and Afghanistan serve as pertinent reminders that the effectiveness of a weapon system is not absolute but is heavily influenced by the specific context of its deployment, the proficiency of its operators, the overarching military strategy, and the adversary's response. Modern warfare, in particular, emphasizes the concept of system integration, where the true power of a military force lies not in individual "game-changer" weapons but in the synergistic combination and effective employment of diverse arms, including artillery, armor, infantry, air power, electronic warfare capabilities, and robust logistical support, all underpinned by well-trained personnel and sound strategic planning.1

A crucial aspect to consider when evaluating the impact of Western weaponry is the quantitative balance of forces and the respective production capabilities of both sides. While precise, real-time data on weapon quantities remains elusive due to the ongoing nature of the conflict and understandable information security measures, certain disparities are evident. In terms of manpower, Russia maintains a significant numerical advantage, with approximately 1.3 million military personnel compared to Ukraine's estimated 900,000.2 This numerical superiority can be particularly relevant in a protracted war of attrition, allowing Russia to absorb substantial losses and continue to generate fighting power. While reports indicate that Russia has suffered considerable equipment losses, particularly in tanks and armored vehicles 2, its larger initial inventory and its capacity to refurbish and redeploy older, Soviet-era equipment have allowed it to partially offset these losses and sustain combat operations.5 Conversely, Ukraine remains critically dependent on the continued supply of weapons and munitions from its Western allies 2, a reliance that introduces a strategic vulnerability to fluctuations in international political will and the production capacities of donor nations.

Beyond the immediate quantities of deployed weapons, the ability of each side to replenish its arsenals and sustain the flow of essential supplies is paramount. In this regard, a significant disparity exists in artillery shell production. Reports indicate that Russia has dramatically increased its annual artillery shell production to approximately three million rounds since the start of the conflict, including a five-fold increase in the production of 152mm shells.8 This substantial production capacity provides Russia with a significant advantage in a conflict characterized by intense artillery duels. In contrast, the combined production capacity of the United States and its NATO allies for 155mm artillery shells is projected to reach approximately two million rounds per year by the end of 2025, following efforts to ramp up production.8 This future projection highlights a current shortfall, especially when considering the historical decline in US artillery ammunition production capacity since the Cold War era.8 Furthermore, Russia has reportedly increased its production of precision-guided artillery rounds 8, suggesting an effort to enhance the quality of its firepower alongside its quantitative advantage. Russia's ability to operate its large Soviet-era factories around the clock underscores its commitment to maintaining a high tempo of production across various categories of military equipment.8 Meanwhile, the Western defense industrial base faces challenges in meeting Ukraine's immediate needs and replenishing its own stockpiles, including long lead times for critical components and a reluctance from some suppliers to commit to long-term contracts.7 This disparity in production capacity for essential munitions can significantly impact the battlefield dynamics, potentially negating the qualitative advantages of some Western weapon systems in a prolonged conflict.

The effective employment of advanced Western weaponry is not solely dependent on its technical specifications but also on the proficiency of the personnel operating it and its seamless integration into existing military doctrines and tactics. While the United States, NATO allies, and partner nations have provided significant training to Ukrainian military personnel on various Western weapon systems, including maintenance and logistical aspects 13, concerns have been raised about the effectiveness of this training in the context of the specific realities of the war in Ukraine.15 Some argue that NATO-style training, often conducted in European settings, may not adequately prepare soldiers for the intense artillery barrages, prevalent drone warfare, and other unique challenges of the Ukrainian battlefield.15 Reports have also emerged suggesting that Ukrainian soldiers are sometimes misusing advanced Western weaponry, such as employing NLAWs in a manner akin to standard RPGs, indicating a potential lack of understanding of the intended NATO tactics emphasizing precision strikes and coordinated maneuvers.16 This "training-reality gap" is further highlighted by observations from Ukrainian soldiers themselves, who note that foreign training may cover basic skills but often misses crucial knowledge for survival, such as effective camouflage, countering enemy drones, and coordinating with comrades under experienced command.15 Moreover, domestic basic military training in Ukraine has reportedly declined in intensity compared to Soviet-era standards 15, potentially impacting the foundational skills necessary for operating any weapon system effectively.

Integrating advanced Western weapons, designed for NATO's combined arms approach, into Ukraine's existing military doctrines, which have historically leaned towards Soviet-era mass and attrition tactics, presents another significant challenge.1 The fundamental differences in these approaches to warfare require not just individual weapon proficiency but also a shift in operational thinking and organizational structures. Instances of newly formed, NATO-trained Ukrainian brigades equipped with modern armored vehicles underperforming compared to experienced units using older equipment underscore the importance of combat experience and established unit cohesion, factors that training and equipment alone cannot fully compensate for.15 The concept of "system integration" and "combined arms warfare" emphasizes that battlefield success hinges on the effective synchronization of various military branches and weapon systems.1 Ukraine may still be in the process of developing the necessary command and control mechanisms and coordination capabilities to fully leverage the potential of Western equipment within a cohesive and effective combined arms framework. Furthermore, a leadership crisis in newly formed Ukrainian brigades, with many commanders lacking significant battlefield experience, can hinder the effective command and control of units equipped with advanced weaponry.15 The allocation of advanced weapons to untrained units while experienced brigades lack such gear further compounds this issue.15

The provision of Western weaponry to Ukraine entails a substantial logistical undertaking, encompassing delivery, maintenance, repair, and the sustained supply of compatible ammunition. While Western nations have provided considerable military assistance 2, the long-term sustainability of this support is subject to various political and economic factors, including potential shifts in donor government priorities and the capacity of their defense industries.2 Maintaining and repairing complex Western weapon systems in an active war zone poses significant challenges, as these systems often require specialized knowledge, tools, storage conditions, and a reliable supply of proprietary spare parts.19 While Ukraine has demonstrated some capacity for domestic repair of certain systems like the M777 howitzer 20, reliance on external suppliers for more complex repairs and spare parts can lead to delays and reduced operational availability.19 The rapid consumption of ammunition for various weapon systems, particularly air defense systems and artillery, places immense pressure on supply chains.5 The difficulties encountered in fulfilling the EU's pledge to supply Ukraine with a million artillery shells highlight the broader challenges in scaling up production and coordinating international deliveries.19

Russia's military has demonstrated a notable ability to adapt its doctrines and tactics in response to the evolving battlefield dynamics and the introduction of Western weaponry. Initially facing challenges in its command and control and reconnaissance capabilities, Russia rapidly incorporated vast numbers of short- and medium-range Unmanned Aerial Systems (UAS) to improve real-time situational awareness and target acquisition.22 Tactically, Russia shifted away from the use of cumbersome Battalion Tactical Groups (BTGs) towards more flexible formations like infantry storm battalions and mechanized breakthrough units, better suited for the terrain and the nature of the conflict.24 The increased use of guided glide bombs has allowed Russian aircraft to strike Ukrainian defenses with greater precision from safer distances.24 Furthermore, Russian forces have shown improved effectiveness in defensive operations, employing a combination of maneuver and well-fortified positional defense to counter Ukrainian offensives.26 This adaptability extends to directly countering Western weapon systems. Russian troops have had the opportunity to study captured or destroyed Western equipment and have actively learned how to counter their effectiveness, particularly in electronic warfare.21 The effectiveness of key Western precision-guided munitions like Excalibur and HIMARS has reportedly been significantly reduced due to Russian countermeasures, including jamming and improved air defense practices.8 Russia has also developed and deployed its own advanced electronic warfare systems to disrupt Ukrainian communications and neutralize drones.21 Despite the influx of Western technology into Ukraine, Russia continues to rely heavily on its traditional strengths in massed artillery fires and infantry-heavy assaults, particularly in offensive operations.17 Russian military doctrine emphasizes artillery as a crucial maneuver element, capable of overwhelming enemy positions with firepower.17 Given its superior production capacity for artillery shells, this strategy of attrition remains a core element of Russia's approach.8

The strategic goals and objectives of both Russia and Ukraine significantly influence the way military force, including Western-supplied weapons, is employed and the overall effectiveness of these efforts. Russia's initial aims of regime change and the subjugation of Ukraine have seemingly evolved towards consolidating control over occupied territories in the east and south, securing a land bridge to Crimea, and potentially exhausting Ukraine's capacity to continue fighting.31 This strategy of attrition aligns with Russia's strengths in manpower and conventional weapons production. Ukraine's primary strategic objectives include preserving its sovereignty and territorial integrity, liberating all occupied territories, and integrating with Western institutions.34 Achieving these ambitious goals requires significant offensive capabilities, and while Western weapons are intended to bolster these capabilities, the scale of the Russian military presence and their defensive fortifications present considerable challenges. Restrictions imposed by Western allies on the use of certain long-range weapons against targets within Russia have also limited Ukraine's ability to disrupt Russian logistics and command structures.36

Russia has actively adapted to the deployment of specific Western weapon systems by developing targeted countermeasures. For instance, the initial effectiveness of the HIMARS rocket system was countered by Russia through the dispersal of ammunition depots, improved camouflage, and the use of electronic warfare to jam GPS guidance.21 The effectiveness of Excalibur guided artillery shells has reportedly plummeted due to Russian electronic warfare capabilities.8 Russia has also significantly increased its own drone production and deployment, alongside developing electronic warfare systems to neutralize Ukrainian drones.21 Modifications have been observed on Russian tanks and armored vehicles to enhance their protection against Western anti-tank missiles and drone attacks.21 There are also reports of Russia learning to target and destroy Ukrainian Patriot air defense systems.23 The increased use of guided glide bombs by Russia allows their aircraft to strike from distances beyond the reach of many of Ukraine's air defense systems.24

Beyond the material aspects of weaponry, non-material factors such as troop morale, leadership effectiveness, and intelligence capabilities play a critical role in determining battlefield outcomes. Initially, Ukrainian forces exhibited high morale and determination 13, which contributed significantly to their initial successes in defending against the Russian invasion. However, the protracted nature of the war and the heavy casualties sustained by both sides can impact morale.36 Reports suggest potential morale issues within some Russian units 38, while Ukraine faces the challenge of replacing battlefield losses and maintaining the morale of its troops.2 Effective leadership at all levels is crucial for maximizing the potential of any military force, regardless of the quality of its weapons.15 Ukraine has faced leadership challenges in newly formed brigades 15, and while it has adopted Western-style mission command in theory, scaling it up effectively has proven difficult.41 Intelligence capabilities are also paramount. The United States has provided significant intelligence support to Ukraine 40, but initial Western overestimations of Russian military strength highlight the complexities of intelligence assessment.43 Russia has also improved its intelligence gathering through the increased use of UAS.22 Potential disruptions in US intelligence sharing with Ukraine could have a significant impact on Ukraine's ability to effectively target Russian forces.40

In conclusion, the lack of a decisive Ukrainian victory despite the provision of Western weaponry stems from a complex interplay of factors. While Western systems may offer technological advantages in certain areas, Russia's quantitative superiority in manpower and its robust production of conventional arms, particularly artillery, provide a significant advantage in a war of attrition. Challenges in training Ukrainian forces to effectively utilize and integrate these advanced weapons, coupled with logistical burdens and Russia's successful adaptation of its military doctrine and development of targeted countermeasures, have further limited the impact of Western technology. The differing strategic goals of both nations and the critical role of non-material factors such as troop morale, leadership effectiveness, and intelligence capabilities also contribute significantly to the current protracted nature of the conflict. Ultimately, the war in Ukraine underscores the reality that modern warfare is a dynamic and adaptive environment where technological superiority alone does not guarantee victory, and a comprehensive understanding of the multifaceted factors at play is essential for analyzing its trajectory.
