Over 300,000 Russian troops have been killed since the start of the Ukrainian invasion, according to Kyiv.
The General staff of Ukraine’s military announced Sunday that Russia had lost 318,570 soldiers and 7,744 artillery systems since February 2022.
Moscow has kept up a campaign of missile, drone and artillery strikes on the country, but is expected to launch a renewed campaign of missile strikes on Ukrainian targets.
This includes its energy infrastructure, as tougher winter conditions influence battle tactics.

These statistics of military losses cannot be independently verified and the Kremlin has yet to comment on the Ukrainian figures.
An update was published by Moscow claiming that 605 Ukrainian soldiers had been killed over the past 24 hours.
It did not provide a Russian estimate of the total Ukrainian losses sustained throughout the conflict.
According to Kyiv, Russia also launched missiles and 76 airstrikes against Ukraine over the previous 24 hours.

In his nightly address on Saturday, Ukrainian president Volodymyr Zelensky said: "As winter approaches, there will be more Russian attempts to make the strikes more powerful.
"It is crucial for all of us in Ukraine to be 100 percent effective."
Ukrainian officials said that fighting continues around the embattled Donetsk town of Avdiivka, which has spent months on the front lines.
Officials added that over 150 of its settlements in the north, east and south of the country came under artillery fire over the past day
Russia did not mention the town in its update, but said its southern grouping of forces had stopped six Ukrainian attacks around the town of Marinka in Donetsk and the villages of Klishchiivka and Shumy.
According to Moscow's Defense Ministry, over 100 Ukrainian troops were killed and three armoured vehicles destroyed in Zaporizhzhia in the south of the country.
The region has been annexed by the Kremlin, but this is not internationally recognized and Vladimir Putin’s forces do not control the entirety of the territory.
Some of the heaviest fighting of Ukraine’s counteroffensive, which began in June, has also been seen in the southern swathe of the country.

It comes as the Ukrainian army says it has pushed Russian troops between three to eight kilometres back on the banks of the Dnipro River.
If confirmed, it would represent the first meaningful one Kyiv’s forces have made months into a counteroffensive that has thus far failed to yield major territorial gains.
Army spokesperson Natalia Gumenyuk said: "Preliminary figures vary from three to eight kilometres, depending on the specifics, geography and landscape design of the left bank."
It was not specified whether the Ukrainian military had complete control of the area or if Russian forces had retreated.
