The assessment follows two FPV strikes on civilian buses in Dnipropetrovsk Oblast on 7 April — part of a pattern that the UN has previously confirmed as crimes against humanity.
ISW assessed on 21 March, adding that Russian forces are unlikely to seize the Fortress Belt in 2026 but will likely make some tactical gains at significant cost.
Ukrainian forces conducted 365 mid-range strikes between March 2025 and March 2026, a third of them in the last three months alone, using domestically produced drones.
ISW's 4 March assessment identified Russian forces pushing Shahed drones into the 0–20 km frontline strip normally dominated by tactical FPVs, citing their heavier payloads as the reason.
