Russia lost territory in Ukraine in April for the first time since 2024, according to the Institute for the Study of War (ISW), which reported Ukrainian forces had gained approximately 116 square kilometres across several frontline areas, including Sumy north of Kharkiv and parts of Zaporizhzhia province. Huseyn Aliyev, a specialist on the war at the University of Glasgow, noted that while Russian advances have slowed significantly since November 2025 and remain sluggish in 2026 compared to the previous year, Moscow has increasingly relied on infiltration tactics to create the illusion of progress. The ISW stated that these infiltrations do not equate to control, as the areas remain within contested "gray zones" interspersed with Ukrainian positions. Erik Stijnman of the Dutch Clingendael Institute described recent movements not as a strategic retreat but as tactical withdrawals, with both sides probing enemy defences along the front. Ivan U. Klyszcz of the International Centre for Defence and Security in Tallinn observed that Ukraine's gains reflect a strategy focused on harassment and disruption rather than static defence. Will Kingston-Cox of the International Team for the Study of Security (ITSS) Verona highlighted Ukraine's deepening strikes on Russian infrastructure, which are forcing Moscow to divert resources to homeland defence. Aliyev added that Russia's recruitment struggles, including aggressive conscription from universities, are reflected in declining troop quality on the battlefield. Despite Ukraine facing even greater challenges in manpower due to its smaller population, Kingston-Cox noted that drone-dominated frontlines have made offensive operations exceptionally dangerous. A key technological shift emerged in February when Starlink cut off Russian access to its satellite network, severely hampering Russian military communications, followed by Kremlin restrictions on Telegram, previously used for tactical coordination. The ISW cautioned that while Ukraine's April gains could have long-term strategic value if expanded, they may prove meaningless if Russia succeeds in dismantling Ukrainian defences over time.
Russia's reliance on infiltration tactics rather than measurable territorial gains suggests its advances are more about perception than military reality. The loss of 116 square kilometres in April exposes the fragility of Moscow's frontline control despite information operations aimed at projecting strength. Ukraine's use of harassment tactics and drone warfare has offset manpower disadvantages, turning technological disruptions like Starlink's cutoff into battlefield consequences for Russian units. Any territorial gain means little if defensive lines collapse later, and right now, attrition favours no one.
