Almost every day since the beginning of the war, Russian officials shout from the stands that the West is "pumping" Ukraine with heavy weapons.

The last such statement was made on October 5 - the Russian ambassador to the USA said that the "decision to prolong the pumping of Kyiv" with heavy weapons makes the USA a party to the conflict. Interestingly, at the same time as this statement, a study by The Wall Street Journal was published, which indicated that the number of weapons left by the Russians during the last "regroupings" now makes Moscow the largest supplier of heavy weapons to Ukraine.

For example, the West supplied Ukraine with 320 tanks - and Russia kept 460; The West provided 210 BMPs, and Russia - 448. Moreover, there are even 40 units of missile systems, while Western supplies provide 70 units.

However, the researchers write, not all equipment is caught on video, so the real number of Russian (working) weapons may be more.
