GoKawiilUkraine airdrops explosive ground robots behind Russian lines in Vivaldi push
Ukraine's Third Army Corps used heavy bomber drones to air-drop explosive ground robots more than six miles behind Russian lines on September 21, 2026, targeting supply routes as part of Operation Vivaldi. Separately, ground robots cleared antipersonnel mines from over 18 miles of routes, a task that would normally require two sapper companies, according to Militarnyi and United24.
