But it’s not just deaths rankling Russia’s forces. Russia has been chipping away at its leadership ranks just by firing them outright, too. General-Colonel Aleksandr Chayko, the former commander of the Eastern Military District, was dismissed in May, according to British intelligence. Russia has likely replaced General-Colonel Aleksandr Zhuravlev with General-Lieutenant Vladimir Kochetkov to head up the Western Military District. General Aleksandr Dvornikov, who was heading up the operation in Ukraine, has also reportedly been dismissed.

The series of killings and firings could be an indication that Russia’s forces are still, nearly six months into the war, mismanaged from the inside out, according to Glen Howard, the president of the Jamestown Foundation.

“I see a lot of that was just kind of their own negligence, and sloppy generalship,” said Howard, who previously worked in the U.S. Embassy in Moscow.

The series of dismissals likely represents Moscow trying to find an approach that works for the war in Ukraine—but the continued hemorrhaging means President Putin probably just hasn’t figured it out yet.

“Putin is definitely adopting a strategy trying to find a fighting general that will succeed,” Howard said. “And luckily for us, he hasn’t found one yet.”
