Russia has removed Sergei Surovikin, nicknamed “General Armageddon”, as head of the air force after he vanished from public view during a Wagner mercenary mutiny against the top army brass, the RIA state news agency reports.

A recipient of Russia’s top military award, General Surovikin would be the most senior Russian military figure to lose his job over the June 23-30 mutiny, which President Vladimir Putin said could have tipped Russia into civil war.

Wagner boss Yevgeny Prigozhin, who spearheaded the revolt, remains at liberty and on Monday posted a video address he suggested was shot in Africa.

The two men Mr Prigozhin had wanted to topple – Defence Minister Sergei Shoigu and Valery Gerasimov, the chief of the General Staff – remain in their posts.

Once commander of Russia’s overall war effort in Ukraine when he was lauded by Russian and Western military experts as one of its most effective operators, General Surovikin has not been publicly fired but RIA cited an unnamed source as saying:

“Ex-chief of the Russian Air and Space Forces Sergei Surovikin has now been relieved of his post, while Colonel-General Viktor Afzalov, head of the Main Staff of the Air Force, is temporarily acting as commander-in-chief of the Air Force”.

Reuters could not independently verify the report and there was no immediate official confirmation.

General Surovikin’s reported removal and the appointment of an acting successor suggest the authorities found fault with his behaviour during the revolt.

United States officials told Reuters in June that General Surovikin had been supportive of Mr Prigozhin, but that Western intelligence did not know with certainty whether he had helped the rebellion in any way.

Given General Surovikin’s reputed competence, some Western military experts have suggested his removal from battlefield operations could hurt Russia’s campaign in Ukraine, something it calls “a special military operation”.

General Surovikin’s last public appearance was on June 24, the second and final day of the mutiny, when he appeared in what looked like a carefully stage-managed video.

Visibly strained and without insignia, he urged Mr Prigozhin to abandon his march on Moscow.

Since the mutiny, which was ended by negotiations and a Kremlin deal, some Russian news outlets and sources have said that General Surovikin, who was often publicly praised by Mr Prigozhin in the run-up to the revolt, was being investigated for possible complicity in it and being held under house arrest.

RIA’s report suggests he remains a member of the Russian military.

It said nothing about his future.

General Surovikin earned the nickname “General Armageddon” during Russia’s military intervention in Syria for the brutal tactics he employed there.

He was placed in charge of Russian military operations in Ukraine last October, but in January that role was handed to General Valery Gerasimov, the chief of the general staff, and General Surovikin was made a deputy to General Gerasimov.

Colonel-General Afzalov was previously deputy to General Surovikin and has been chief of staff of the Aerospace Forces for at least four years, according to British military intelligence.

Ukraine says he played a direct role in the planning and prosecution of Russia’s onslaught against it.

During General Surovikin’s absence from public view, Colonel-General Afzalov was shown on television briefing General Gerasimov last month.
