Russia Adapts Military Tactics Four Years into Ukraine Invasion Amidst High Casualties

Four Years of Conflict Mark Tactical Evolution

As the full-scale invasion of Ukraine enters its fifth year, the Russian Federation's armed forces have demonstrated a notable evolution in their military tactics. This adaptation, particularly evident in the domains of artillery, electronic warfare, and drone deployment, comes amidst significant casualties on both sides. Since February 24, 2022, Russian forces have reportedly suffered approximately 1.2 million casualties, including killed, wounded, and missing, with as many as 325,000 killed. Combined Russian and Ukrainian casualties could reach 2 million by spring 2026. Civilian casualties have also been substantial, with at least 15,172 killed and 41,378 injured since the invasion began.

Artillery Remains a Central Pillar of Russian Strategy

Artillery continues to be a primary form of lethality for Russian forces in Ukraine, central to their ability to maintain positions against Ukrainian advances. Russian adaptations include the refinement of the 'reconnaissance-fire system,' which integrates tactical intelligence, surveillance, and reconnaissance assets with precision strike artillery in real-time. The Strelets system exemplifies this, connecting sensors to artillery for rapid engagement. Unmanned Aerial Vehicles (UAVs), such as the Orlan-30, are frequently used for target designation, guiding precision munitions like the 2K25 Krasnopol 152mm laser-guided round. Russia has also increased the production and supply of precision-guided artillery munitions, including the Krasnopol-M2 and Gran. Tactics like 'shock-fire,' which involve using UAVs and artillery-locating radars to provoke and then counter enemy fire, have been noted. Russian forces are estimated to be firing around 10,000 artillery rounds daily.

Electronic Warfare Capabilities Show Enhanced Effectiveness

Russia has heavily invested in electronic warfare (EW) capabilities, deploying sophisticated systems designed to disrupt enemy communications and targeting. Systems like Krasukha-4 for radar jamming, Leer-3 for cellular network disruption, and Murmansk-BN for strategic electronic disruption have been utilized. EW is considered integral to Russian efforts to degrade Ukrainian command and control (C2) and intelligence, surveillance, and reconnaissance (ISR) capabilities by targeting radio, satellite communications, radars, and Global Navigation Satellite System (GNSS) signals. Experts suggest that Russian EW systems have been effective, reportedly causing up to '90% of guided missile and drone systems supplied by the U.S. to Ukraine to miss their target,' including HIMARS. These systems have also adapted to jam new U.S. and NATO weapon systems and are proving increasingly effective against Ukrainian air defense systems such as Patriot and Hawk missiles. The disruption of Ukrainian forces' ability to coordinate, collect intelligence, and launch drone attacks, including interference with Starlink internet capabilities, has been attributed to Russian EW.

Drone Usage Transforms Battlefield Dynamics

The role of drones in the conflict has undergone a significant transformation, evolving from peripheral reconnaissance tools to a strategic component of Russia's warfighting strategy. Initially, Russia lagged in drone capabilities but has since acquired thousands of units and technology, notably from Iran, and developed its own production. By the third year of the war, drones were being integrated with AI technologies to enhance evasion of air defenses and improve target identification, marking a shift towards semi-autonomous, EW-resilient drone warfare. The use of SuperCam reconnaissance drones, equipped with radio detectors for threat sensing, has also been observed. A key innovation is the widespread deployment of fiber-optic drones, which are immune to jamming technologies due to their wired control, making them difficult to intercept. These were notably used in late 2024 to push Ukrainian troops out of Russia's Kursk region. Russia's 'Rubicon' drone unit has emerged as a significant force, focusing on disrupting Ukrainian supply lines and expanding kill zones. First-person view (FPV) drones are extensively used, including for striking civilian targets in near-rear areas, and 'mothership drones' are employed to extend the range of smaller FPV drones, overcoming limitations and EW interference.

Conclusion

The ongoing conflict in Ukraine has spurred significant tactical adaptations within the Russian armed forces. The enhanced integration of artillery with advanced reconnaissance, sophisticated electronic warfare capabilities, and a rapidly evolving drone program underscore Russia's efforts to gain an advantage on the battlefield. These adaptations reflect a continuous learning process in response to battlefield realities, even as the conflict continues to incur a heavy human toll.
