Russian Major General Anton Grunis, commander of the 4th Separate Guards Motor Rifle Brigade, was killed in a Ukrainian drone strike in the Russian-occupied Donetsk region, according to footage and statements released by Ukraine's Unmanned Systems Forces. Commander Robert Brovdi said the strike took place on the night of September 12, targeting Grunis at what he described as the general's nighttime hideout, with the operation carried out by the elite 427th Separate Unmanned Systems Brigade known as Rarog. Grunis led forces along the Bakhmut and Kostiantynivka axes and had personally briefed Vladimir Putin in July on Russia's claimed capture of Kostiantynivka. Brovdi says Grunis is now the seventh Russian commander at brigade, division or army level confirmed killed by his drone units.

The strike lands as a significant symbolic blow to Moscow, since Grunis had just weeks earlier been awarded Russia's prestigious Hero of the Russian Federation title, personally presented by Defense Minister Andrey Belousov in late August. Russian sources have offered conflicting details on his death, with a military alumni channel and a commander from Russia's Akhmat special forces both acknowledging he had died, though Russia's Defense Ministry has not issued an official confirmation. His killing follows closely on reports that a Russian lieutenant general commanding the 51st Combined Arms Army was also struck days earlier, adding to a string of high-profile losses among Russia's senior field commanders. Ukrainian officials have not independently verified every detail surrounding the circumstances of Grunis' death, but the drone footage and Brovdi's account point to a carefully planned and executed strike on a rising star within Russia's military command.
