The Special Night Squads (SNS) (Hebrew: "Plagot Ha'Layla Ha'Meyukhadot", פלוגות הלילה המיוחדות) was a joint British-Jewish counter-insurgency unit, established by Captain Orde Wingate in Mandatory Palestine in 1938, during the 1936–1939 Arab revolt. The SNS basically comprised British infantry soldiers, together with some men drawn from the Jewish Supernumerary Police. Total unit strength was 100 by 1938. Wingate selected his men personally, among them Yigal Allon and Moshe Dayan, and trained them to form small mobile striking units. Wingate also collaborated with the Jewish paramilitary formation, the Haganah, reinforcing his unit with some of Haganah's Fosh commandos. Given British opposition to the formal creation of Jewish military units, it is not clear to what degree the authorities were aware of the exact details of Wingate's operations in this regard.
