Russian casualties in Ukraine are nearing 550,000, according to figures published by Ukraine's military, with reported artillery, vehicles and other equipment losses closing in on new milestones.

Ukraine's armed forces said on Wednesday that Russia had sustained around 546,270 casualties in Ukraine since February 2022, including 1,180 fighters killed or injured in the past day. Publishing updated figures, Kyiv also said Russia had lost 57 artillery systems in the previous 24 hours, bringing Ukraine's tally of Russia's total artillery losses close to 15,000.

According to Ukraine's numbers, Moscow has lost a combined total of nearly 20,000 vehicles, including fuel tanks. This does not include tanks and armored personnel carriers or infantry fighting vehicles, which are counted separately. Russian troops have also lost close to 2,500 items of what Ukraine's armed forces dub "special equipment," the updated count from Kyiv's military indicates. A broad term, "special equipment" covers losses of assets such as electronic warfare systems, radars and maintenance vehicles.

Newsweek could not independently verify Ukraine's numbers and has reached out to the Russian Defense Ministry for comment via email. Casualty counts and battlefield losses are murky during active conflicts, and experts urge caution when dealing with tallies offered up by either party in a war.

The British government estimated in late May that Russia's total casualties had likely reached 500,000. Throughout May 2024, Moscow's average daily casualty count stood at more than 1,200, the U.K. Defense Ministry said, marking the highest monthly average number of daily losses for Russia of the full-scale war.

Kyiv's Defense Ministry said on Monday that Moscow had sustained more than 35,000 casualties throughout June, marking the second-highest number of casualties in a single month since February 2022.

Russia has made slow but steady gains, particularly in the heart of the fighting in eastern Ukraine, in recent months, but at a huge cost to its personnel. Western intelligence and experts suggest many of the Russian soldiers currently on the front lines have limited training—often volunteers or convicts—and cannot carry out complex operations.

Ukraine has said Russia is able to pull up to 30,000 new soldiers each month into its ranks, propping up the bloody and casualty-heavy tactics Moscow has used against Kyiv's forces to make slow but consistent territorial gains.

In a separate statement, Ukraine's government said earlier this week that Russia had lost a "record" number of artillery systems in the last month, adding in a post to social media that "1,415 [R]ussian artillery systems were destroyed in June."
