Anka the Machinegunner. A famous WWI Red Army folk heroine and sex symbol. Anecdotes of her and her commander Chapayev and friend in arms Petka count by the hundreds, and very few of them (if at all) are not R rated.
Sorry if I am being boring, but Anka's story is a bit different. She never fought in WWI and in fact she never even existed. Anka was first introduced in famous 'Chapayev' movie by Vasilyev brothers which was released in 1934 and immediately became a big hit in the USSR. In the movie, Anka joined the Chapayev's regiment during the Russian Civil War and became a machinegunner. She also fell in love with Chapayev's aid Pyotr (Petka). Anka was portrayed by Varvara Myasnikova. Originally, Anka was meant to be a strong and independent woman, a role model for Soviet women. Later on, in 1960-1970s, Anka, Petka and Chapayev became heroes of countless anecdotes (funny stories) which often was quite NSFW. After 1991, their image undergone further change in this direction, especially in computer games.
