Destruction battalions, colloquially istrebitels (истребители, "destroyers", "exterminators") abbreviated: istrebki (Russian), strybki (Ukrainian), stribai (Lithuanian), were paramilitary units under the control of NKVD in the western Soviet Union, which performed tasks of internal security on the Eastern Front and after it. After the Fall of the Soviet Union the battalions were deemed by the Riigikogu (Parliament of Estonia) to be a criminal organisation.Okupatsioonirežiimi kuritegudest Eestis [On Crimes of the Occupational Regime in Estonia] Riigi Teataja from 18 June 2002
