Тачанка! Tachanka!

'Tachanka' (Russian: Тачанка) or 'Song of the Tachanka' (Russian: Песня о Тачанке) is a Soviet revolutionary song written in 1937 by Mikhail Ruderman. While it was wrote several years after the war's conclusion, the song happily commemorates the Tachankas that were used by the Red Army during the Russian Civil War.
The Tachanka consisted of a machine-gun cart drafted by horses, which was quite common due to Russia's lack of heavy machinery at the time.
