T-34. T-34/76 „Sotka“. In: Finnish Army 1918–1945: T-28 and T-34 tanks. jaegerplatoon.net, abgerufen am 21. Februar 2015 (englisch): „Finnish soldiers gave already first captured T-34 tank a nickname „Sotka“ (pochard) and this nickname spread becoming a commonly used nick-name for all T-34/76 tanks. Several more or less varying stories exist about origin of this nickname, but most seem to have that in common, that apparently the inspiration for it originated from a steamboat with that name.“
