"White Tights" (also "White Pantyhose" or White Stockings; the "beliye kolgotki", Russian: белые колготки ; Latvian: "baltās zeķbikses" ; Estonian: "valged sukkpüksid" ) is a Russian urban myth surrounding the alleged participation of female sniper mercenaries in combat against Russian forces in various armed conflicts from late 1980s.
 The myth describes these women as blond Amazon-like nationalistic biathletes turned anti-Russian mercenaries.
 They come predominantly from the Baltic states, but subsequent variations of the myth have diversified the ethnic composition of the snipers, including Ukrainian, Russian women in their midst.
 The name "White Tights" originates from the white-coloured winter sports attire these snipers were wearing and was first coined during the Nagorno-Karabakh War.
