The “Apachi” UAV unit of the 81st Airmobile Brigade reported repelling the most massive enemy motorcycle assault of the year. On March 31, Russian forces deployed 16 motorcycles carrying up to 48 infantry, with 2–3 assault troops on each bike. The assault groups moved in formations of 3–4 vehicles from the area of Siversk. A significant portion of the attacking personnel was eliminated on approach to Ukrainian positions. Those who managed to break through were later neutralized by airborne troops and adjacent units.
