According to the BBC Russian Service, the conflict between Russia and Ukraine is entering a new phase. While Ukraine's production capacity of various types of drones is increasing, the quality and attack power of these vehicles are also rapidly rising. This situation affects not only the front line but also Russia's military and logistical infrastructure in depth. Ukraine's cost-effective and efficient attack tools enable regular strikes on targets such as factories and oil depots. The advance of the Russian army has generally slowed down. As of May 2026, the war largely continues in the form of trench warfare, with limited advances in the Donetsk and Zaporizhzhia regions by Russia. Although the Russian military command continues to present success reports, independent sources and military observers indicate that Russia's losses exceed the territories it has captured. The Russian army tries to protect experienced soldiers while generally reinforcing front-line units with less trained and contract soldiers. However, deep strikes carried out by Ukraine's drones threaten Russia's logistics and command points from distances of 100 kilometers or more. These new war dynamics make it difficult for the Russian army to continue advancing with current methods.
