Pravda: Катюша - Katyusha (Girls und Panzer)

The song is about a Russian woman called Katyusha. Standing on a steep riverbank, she sends her song to her lover, a soldier serving far away. The theme of the song is that the soldier will protect the Motherland and its people while his grateful girl will remain true to him. Its lyrics became relevant during the Second World War, when many Soviet men left their wives and girlfriends to serve in World War II, known in Russia as The Great Patriotic War.
