Putin last week used the word "war" to describe the conflict, the start of which he dates to 2014.
Moscow: Some Russian officers fighting in Ukraine are unhappy with the military top brass and President Vladimir Putin because of the poor execution of the war, an influential nationalist Russian blogger said after visiting the conflict zone, Reuters reported.
Nearly 10 months since Putin ordered troops into Ukraine, there is no end in sight to the deadliest conflict in Europe since World War Two.
In modern Russia, direct public criticism of Putin is rare though nationalist bloggers have been outspoken about the conduct of the war, especially the costly Russian defeats in Ukraine's Kharkiv region in September.
Igor Girkin, a nationalist and former Federal Security Service (FSB) officer who helped Russia annex Crimea in 2014 and then organise pro-Russian militias in eastern Ukraine, said there was some discontent with the top brass, Reuters reported.
In a scathing 90-minute video analysing Russia's execution of the war, Girkin said the "fish's head is completely rotten" and that the Russian military needed reform and an intake of competent people who could lead a successful military campaign.
Some at the mid-levels of the military, Girkin said, were open about their dissatisfaction with Defence Minister Sergei Shoigu and even Putin.
"It is not just me... people are not blind and deaf at all: people at the mid-level there do not even hide their views which, how do I put it, are not fully complimentary about the president or the defence minister," Girkin said.
Russia's defence ministry did not comment on the remarks from Girkin who has repeatedly criticised Shoigu, a close Putin ally, for the battlefield defeats Russia has suffered in the war.
Both Ukraine and Russia say the other side has sustained devastatingly high casualties, though neither gives clear data on their own losses.
The United States' top general estimated on Nov. 9 that Russia and Ukraine had each seen more than 100,000 of their soldiers killed or wounded. The civilian death count is unknown.
Russia passed laws shortly after the invasion which allow prison terms of up to five years for actions interpreted as discrediting the armed forces, or up to 15 years for disseminating deliberately false information.
'1917'
Putin last week used the word "war" to describe the conflict, the start of which he dates to 2014 when a pro-Russian president was toppled in Ukraine's Maidan Revolution and Russia annexed Crimea, with Russian-backed separatist forces fighting in eastern Ukraine.
Putin casts what he calls Russia's "special military operation" as a watershed moment when Russia finally stood up to the arrogant West, led by the United States, after decades of humiliation since the 1991 fall of the Soviet Union.
Russia, Putin says, is defending Russians in Ukraine against a decadent West that ultimately wants to carve up Russia's vast resources and eradicate Russian civilisation. The West denies such a plot.
Ukraine and the West say Putin has no justification for what they cast as an imperial-style war of occupation. Ukraine says it will fight until the last Russian soldier is ejected from its territory.
The West, Girkin said, wanted to foment a revolutionary situation in Russia akin to the February Revolution in 1917 when Tsar Nicholas II abdicated amid popular and elite anger over Russian failures in World War One.
Russia, he said, had a lack of effective tactical missiles and it was unclear if it could produce enough while Russia had failed to establish air superiority due to Ukrainian air defences.
"Our Ministry of Defence has simply slept through the fact that the whole world has moved to new tactical aviation," he said.
Girkin was convicted in absentia by Dutch judges for murder over his role in the shooting down of Flight MH17 over Ukraine in 2014 with the loss of 298 passengers and crew. Russia, which has repeatedly denied downing the jet, rejected the verdict.
