Ukrainian assault troops suffered more than 10 times fewer casualties than Russian forces during Operation Vivaldi, a Ukrainian military veteran said on 9 October, describing the ratio as unprecedented and highlighting Ukraine’s improved ability to protect its soldiers during offensive operations.
The counteroffensive has been a significant Ukrainian success, reclaiming territory in northern Donetsk Oblast and disrupting Russia’s plans to advance toward Sloviansk and Kramatorsk. The reported casualty ratio points shows Ukraine’s ability to make offensive gains while reducing the human cost of assaulting fortified positions.
Yevhen Dykyi made the remarks in an interview with Radio NV, saying the results showed how Ukrainian forces had learned to limit losses while attacking defended Russian positions.
Protecting troops during offensive operations
Dykyi said the casualty ratio was one of the operation’s most important outcomes.
He said that Ukrainian assault troops suffered more than 10 times fewer casualties than Russian forces during the counteroffensive.
“That speaks volumes. We have learned how to protect our people, and that is extraordinarily vital,” he added.
Operation Vivaldi disrupted Russia’s advance in Donetsk
The Third Army Corps launched Vivaldi in mid-September in northern Donetsk Oblast, near Lyman, where Russian forces had spent months trying to advance toward Ukraine’s fortified cities of Sloviansk and Kramatorsk.
The operation aimed to clear Russian troops from positions north of Lyman and disrupt Moscow’s plans to encircle the remaining Ukrainian-held parts of Donetsk Oblast. Ukraine’s Third Army Corps announced the counteroffensive on 15 September, initially reporting that its forces had cleared Russian infiltrators from several settlements and liberated Serednie.
By 30 September, Ukraine had regained 176 square kilometers of territory during the operation, according to figures cited by the Ukrainian presidential office. Ukrainian authorities also reported that their forces had captured around 250 Russian soldiers and inflicted more than 5,000 Russian casualties, including killed and wounded.
The counteroffensive also disrupted Russia’s effort to advance behind Ukraine’s fortified defensive line. By threatening Russian positions north of Lyman, Ukrainian forces complicated Moscow’s plans to encircle the Sloviansk-Kramatorsk area rather than attack its defenses head-on.
Unmanned systems help limit casualties
A key feature of Vivaldi has been the use of unmanned systems to attack fortified Russian positions before Ukrainian infantry moves in. Ukrainian forces deployed ground robots carrying grenade launchers to fire into Russian shelters, while explosive ground vehicles were used to destroy bunkers and strongpoints.
In one reported tactic, heavy drones delivered kamikaze ground robots more than 10 kilometers behind Russian lines, allowing Ukrainian operators to attack positions without exposing infantry to direct fire.
