The initial phase of the Russian invasion of Ukraine
On 24 February 2022, Russian forces crossed the Sumy and Chernihiv regions of Ukraine and entered Pripyat from Belarus. (see Figure 1). The initial assessment of the Russian commanders was that Russia would take control of Ukraine in 10 days. Despite the odds, Ukraine re-configured its forces and adopted the North Atlantic Treaty Organisation (NATO) practices in its operations since the conflict in Donbas in 2014. Other factors, such as familiarity with the terrain and better intelligence networks, helped Ukrainians push Russian forces back from Sumy, Chernihiv, and Kharkiv. Russian forces achieved some gains in the early days by seizing southern Zaporizhzhia and Kherson. The Russian offensive was slowed down because of an initial shortage of manpower. Ukrainian forces outnumbered Russian forces, having implemented a general mobilisation across Ukraine on the day of the invasion. Further, Kyiv’s capabilities were bolstered by Western support in the form of weapons and intelligence. For instance, Space X’ universal internet service, Starlink, was provided to the Ukrainian Armed Forces (UAF), enabling troops to share real-time data anywhere combined with high-precision weapons such as the Multiple Launch Rocket System (MLRS) and High Mobility Artillery Rocket System (HIMARS) launchers (see Table 1). This helped Ukraine gain the tactical edge early on in the conflict. Three months into the war, in May 2022, the US Congress also passed the Lend-Lease Act for Kyiv, which granted Ukraine access to American weapons.

As a result of Western assistance, Russia withdrew from Kherson city, fearing their supply lines being cut off due to Ukrainian bombings of the trans-Dnieper bridges, which was a major victory for Kyiv. The West increased military aid to Ukraine in the form of tanks. Additional units were created and troops were replenished. Kyiv could have inflicted maximum damage on Russian forces during this period, but it missed the opportunity to begin its offensive from Zaporizhzhia to the Sea of Azov to cut Russia’s access in Kherson or continue its offensive in Luhansk. The reason for not doing so was likely Washington's hesitation regarding Ukraine’s capabilities to undertake such an operation.

Ukraine’s summer offensive
The Ukrainian forces delayed the launch of their offensive in early 2023 awaiting weapons deliveries from the West. On 8 June, Ukraine finally launched their offensive in the direction of Zaporizhzhia and Donetsk. Ukraine’s delay in launching its offensive resulted in Russia recovering and consolidating its gains further. Russian satellites could track and counter Ukrainian forces' movement. The Russian armed forces began building a network of field positions and fortifications and added more troops. Further, Russian forces were able to make some gains in Soledar and Bakhmut, and by July, after the Wagner mutiny, Moscow began their offensive towards Kupiansk.
A key reason for the difficulty in making territorial gains by both sides is due to technological advances. The use of Unmanned Aerial Vehicles (UAVs) and First Person View (FPV) drones and surveillance of the frontline rendered traditional approaches ineffective, as amassing troops at a single point would expose them to drone attacks. Drones have been the game changer in this conflict. In some instances, drone operators reported more enemy fatalities than artillery. Drones are marginally cheaper and easily deployable, and they have come to aid both sides. Moscow was able to turn the tide with the help of drones; the Russian forces began to advance in 2023-2024, capturing Avdivika and then pushing towards Kupiyansk in Lugansk. Ukraine, in response, increased its drone attacks inside Russia, targeting energy infrastructure such as oil processing facilities and military facilities.

Yet Russian forces were able to make gains with their ‘multiple cuts’ strategy deploying forces across the conflict line limiting Ukraine’s options. However, with the US$61 billion aid package announced in May 2024 and Ukraine securing permission from the US to use the Army Tactical Missile System (ATACMS), Kyiv continued cross-border strikes and attacked two early warning nuclear radar stations in Krasnodar and Orsk.
Ukraine’s Kursk incursion
On 6 August 2024, Ukrainian troops crossed into Kursk and later into the Belgorod region. Moscow declared a state of emergency in Kursk a day after the incursion and later in Belgorod as Russia began deploying troops to counter the Ukrainian forces. Kyiv’s advance broke the momentum of the Russian armed forces early this year. Ukrainian General Oleksandr Syrskyi’s tactful move has resulted in Russia repositioning itself to manage a two-front challenge in Eastern Ukraine and its territory. The Ukrainian advance was to consolidate as much territory as possible before entering peace talks.
As Russia advanced Westward, Ukrainian forces moved in from Sumy, where the Russian border is covered by vast forests, camouflaging armed formations near the border with Kursk. (See Fig 1.4). Ukrainian forces exploited the gaps and preserved the element of surprise till the very end. At the end of the first week of the incursion, Ukraine seized control of a Sudzha, which is a crucial hub for the transit of Russian natural gas to Europe and reportedly blew up three key bridges over the Seim River, cutting off Russia’s supply lines. The calculations of this incursion were likely to force Russia to the negotiating table, create a buffer zone, and shift the focus of the conflict from Eastern Ukraine to Western Russia to relieve the pressure of Ukrainian forces fighting in Eastern Ukraine. In response, Moscow announced the establishment of troop groups in Kursk, Bryansk, and Belgorod Oblasts to defend settlements along the border with Ukraine. Russian forces began the construction of defensive lines and fortifications near Lgov and Kursk Oblast and were able to slow down the Ukrainian advance. In September, Russia launched a counter-attack regaining control of several settlements in the Kursk region.

However, contrary to the expectations of Ukrainian commanders, the Russian advance in Eastern Ukraine did not slow down nor were the Russian troops fighting in Donetsk re-directed to Kursk. Rather, Russian forces have made considerable gains reaching the gates of Pokrovsk city and successfully encircling the city of Vuhleder, both in Donetsk. The speed of the Russian advance and its quick recovery from the Ukrainian incursion in Kursk has limited options for Ukrainian forces.

As NATO countries deliberate on giving consent to Ukraine to strike deep inside Russia, the Kursk incursion, despite effective execution, has not yielded the results Ukraine foresaw. The coming months are crucial, as the elections in the United States could be the biggest determinant of the conflict.
